BACKGROUND Field

The present disclosure relates to cooling and ventilation systems for building structures.

Description of the Related Art

Heating and cooling the space in residential and commercial buildings accounts for a primary share of building energy consumption. Occupants or persons otherwise associated with building heating and cooling may either not know when it is optimum to use a heating and cooling system or otherwise not properly utilize the heating and cooling system.

SUMMARY

When the outside ambient air temperature is lower than the internal air temperature, outside ambient air can instead be used to effectively cool the home or building structure, reducing the need to run a costly air conditioning system. Further, air conditioning systems merely circulate air located within a building structure, and do not bring any outside air, so any harmful environmental elements (e.g. dust, disease, chemicals) may remain within the building structure.

A whole house fan can be used to move air through the building structure when desired outside and/or inside conditions allow. Whole house fans include one or more high cubic feet per minute (cfm) fans, typically placed in the attic of a building structure, and function by creating a negative static pressure inside of the building structure to draw air in from the outside. The outside air is moved through the ceiling into the attic where the air is exhausted out through a vent by positive static pressure in the attic or upper floor. Louvered shutters can be placed over the vent to prevent cooled or heated air from escaping when the whole house fan is not in use. Whole house fan systems move large amounts of air and allow for the entire building structure air volume to be recycled with multiple air exchanges per hour, removing latent heat within the building structure. Advantageously, whole house fan systems typically require less energy than air conditioning systems and can reduce the need for air conditioning, therefore reducing energy consumption while providing a comfortable space for building occupants. The systems and methods disclosed herein provide a more efficient and cost effective cooling and ventilating of interior spaces of a building structure while improving the indoor or interior air quality.

In some embodiments, a fresh air cooling and ventilating, fresh air cooling, fresh air ventilating, or fresh air system disclosed herein may use open windows to serve as intake air vents. In some embodiments, the user may manually open the windows to allow for airflow into the building structure. The fresh air cooling and ventilating system can control for and/or notify a user when a whole house fan may not be effective at cooling the building structure such as, for example, when the outside temperature is higher than the inside temperature. The fresh air cooling and ventilating system may also be connected to a thermostat and an air conditioning system to avoid, for example, the air conditioning system running (being activated or operating) while the whole house fan is running (activated or operating), mitigating possible energy savings. The air conditioning systems discussed herein can include systems with a vapor compression refrigeration cycle.

In some embodiments, the fresh air cooling and ventilating system can determine the temperature of the interior and/or exterior of the building structure and other parameters such as humidity. The fresh air cooling and ventilating system can use these input parameters to control activation of a whole house fan system and/or air conditioning system. The fresh air cooling and ventilating system can be connected to and at least partially control an air conditioning system. The fresh air cooling and ventilating system can be connected to an automated or automatic window system. The fresh air cooling and ventilating system can control one or more automated window(s) to automatically open or close window(s) to, for example, serve as intake air vent(s) for the whole house fan system.

The fresh air cooling and ventilating system can include one or more controller(s) that provides for automatic and/or manual control of certain parts of the system. The controller(s) can operate in various modes ranging from automatic operation of the system to substantially manual operation of the system. For example, in an automatic mode, the controller(s) can collect a variety of information from temperature sensors, humidity sensors, air quality sensors (such as for example sensors for detecting volatile organic compound (VOC) gases, carbon dioxide, carbon monoxide, smoke, particulates, and/or pollen), weather information, and/or other information via a variety of input sources, including sensors and the internet via cloud services. The controller(s) can determine when conditions permit for operation of the whole house fan system or the air conditioning system. For example, the fresh air cooling and ventilating system can turn off the air conditioning system and operate the whole house fan if it is cooler outside than in the interior space of the building structure. Alternatively, if it is hot outside, the fresh air cooling and ventilating system can allow the air conditioning system to operate. The fresh air cooling and ventilating system can also operate the whole house fan if there are undesired air pollutants (based on AQI levels) inside the building structure by bringing in fresh air from the outside.

Accordingly, the fresh air cooling and ventilating system can be operated in a variety of modes. An automatic mode allows the system to operate with minimal or no user input after, for example, selection of the automatic mode. The fresh air cooling and ventilating system can be operated in a semi-automatic mode, which may prompt the user for certain input before, during, and/or after operation. The fresh air cooling and ventilating system can be operated in various selectable modes ranging from automatic to manual (including semi-automatic) depending on the user input for desired operation and/or devices, such as automated windows, connected to the fresh air cooling and ventilating system.

The fresh air cooling and ventilating system can be controlled by the user utilizing a variety of methods. In some embodiments, one or more user devices are positioned within the building structure from which the user can control the system. The user device can display information about the fresh air cooling and ventilating system to the user. In some embodiments, the user can use a smart phone application or a web application connected to the fresh air cooing system over the internet or via a Bluetooth connection to control the fresh air cooling and ventilating system. Similar to the user device, the smart phone application or web application can display information about the fresh air cooling and ventilating system to the user.

DETAILED DESCRIPTION

Embodiments of the present disclosure provide for a fresh air cooling and ventilating system. The fresh air cooling and ventilating system can include a motorized whole house fan, a vent system, motorized automatic window(s), user device(s), connection(s) to thermostat(s) or other devices that control an air conditioning system, and/or controller(s) that control the fresh air cooling and ventilating system and/or air conditions system. The use of a fresh air cooling and ventilating system in a building structure presents several advantages over the use of a traditional air conditioning system, including decreased energy usage and greater circulation of fresh ambient air, thereby reducing the amount of dust and contaminated air in the building structure.

In some embodiments, the fresh air cooling and ventilating system can include motorized automatic window(s) (automatic window(s)), that can be connected to the one or more controllers. The one or more controllers can open and close the motorized automatic windows when the fresh air controller detects desired or predetermined conditions discussed herein. Automated window(s) can help increase utilization and ease of use of the fresh air cooling and ventilating system. For example, in order to run the whole house fan, a user may not need to manually open windows to allow for fresh air to be drawn into the building structure.

The one or more controllers can include a fresh air controller that can be connected to a whole house fan controller (motorized fan controller), which operates the whole house fan. The fresh air controller can also be connected to a thermostat controller of a thermostat. The thermostat controller can control an air conditioning system that can maintain a desired temperature inside the living/interior space of the building structure. In some embodiments, the fresh air controller and all associated controls, algorithms, and/or modes of the fresh air system as discussed herein can be incorporated into the thermostat as a separate controller in the thermostat or as thermostat controller itself. Accordingly, the controls, algorithms, and/or modes that are part of and/or executed by the fresh air controller can be part of and/or executed by the thermostat controller. For example, the controls, algorithms, and/or modes of the fresh air controller discussed herein can be part of the thermostat controller in new home/building installations, and/or an existing thermostat controller can be updated and/or upgraded with the controls, algorithms, and/or modes of the fresh air controller as discussed herein.

Coordination between utilization of the whole house fan system and the air conditioning system can mitigate running the whole house fan system when conditions are better for running an air conditioning system (for example, the outside temperature is hotter than the inside temperature) or running the air conditioning system when conditions are better for running the whole house fan system (for example, the inside temperature is hotter than the outside temperature). The fresh air controller can receive information via a connection to the internet in addition to receiving input from temperature and other kinds of sensors both inside and outside of a building structure. In some embodiments, the fresh air controller can be connected to a ventilation fan, which can be positioned in the attic area of the building structure. The ventilation fan can help draw the exhaust of the whole house fan from the attic.

In some embodiments, the fresh air controller can receive data associated with an outside temperature value corresponding to ambient temperature around the building structure and an inside temperature value corresponding to temperature inside the living space. The fresh air controller can receive temperature data via temperature sensors connected to the fresh air controller. The temperature sensors can be located in and around the building structure, including in the attic space, the living/interior space, and the ambient environment outside the building structure. In some embodiments, the fresh air controller can receive temperature data corresponding to an outside temperature value from an online source via a connection to the internet. In some embodiments, the fresh air controller can receive any temperature data discussed herein via a temperature sensor and/or the internet. The temperature sensors can be connected via any wired or wireless connection discussed herein.

In some embodiments, the fresh air controller can receive a humidity value corresponding to the humidity level inside the building structure and/or in the ambient air outside of the building structure. The fresh air controller can receive the humidity value either from a humidity sensor in wired or wireless connection with the fresh air controller or from an online source via a connection to the internet. The humidity sensor(s) can be located in and around the building structure, including in the attic space, the living/interior space, and the ambient environment outside the building structure. In some embodiments, one or more humidity sensors maybe part of and/or positioned in a user device.

In some embodiments, the fresh air controller can receive an air quality value corresponding to the air quality level inside the building structure and/or in the ambient air outside of the building structure, including information about and/or levels of volatile organic compound (VOC) gases, carbon dioxide, carbon monoxide, smoke, particulates, and/or pollen. The fresh air controller can receive the air quality value either from an air quality (AQI) sensor in wired or wireless connection with the fresh air controller or from an online source via a connection to the internet. The AQI sensor(s) can be located in and around the building structure, including in the attic space, the living/interior space, and the ambient environment outside the building structure. In some embodiments, one or more AQI sensors maybe part of and/or positioned in a user device. In some embodiments, one or more AQI sensors may standalone devices that are plugged into the electrical system or plug of a building structure. For example, carbon dioxide, carbon monoxide, and/or smoke detectors may be plugged into a plug of the building structure and connected (e.g., wirelessly) with the fresh air controller.

As used herein, humidity is used in its broad and ordinary sense and includes, for example, a measurement of the concentration of water vapor in the air. A relative humidity or humidity value as used herein falls between 0-100% (percent). High humidity in the interior air of a building structure can cause water damage to the interior of a building structure as well occupant discomfort. For these reasons, it can be advantageous to run the fresh air cooling and ventilating system when there ambient air outside the building structure is below a certain level of humidity.

In some embodiments, the fresh air controller can receive an air quality index data corresponding to the air quality index value in the ambient air outside of the building structure. As used herein, an air quality index is used in its broad and ordinary sense and includes, for example, a value that corresponds to the level of pollution in the air. For example, an air quality index can be utilized to convey the level of risk a person will encounter by breathing the ambient air. Air quality index is usually provided on a scale of 1-1000. Air quality index values in a range of 1-50 are considered excellent with no health implications. Air quality index values of 51-100 are considered good with only slight effects on individuals who are very sensitive to pollutants. Air quality index values between 101-150 are considered lightly polluted, and healthy people may experience slight irritation. Air quality index values between 151-200 are considered moderately polluted, and it is recommended the general population moderately reduce outside activity with those more at risk being advised to avoid outdoor activity. Air quality index values between 201-300 are considered heavily polluted, and the general population is advised to reduce outdoor activity. Air quality index values above 300 are considered severe pollution, and it is recommended that the general population should avoid outdoor activity.

In some embodiments, the fresh air controller can control the operation of the whole house fan and/or the air condition system based on a comparison between the inside and outside temperature values as well as comparing other data values including the outside temperature data, inside temperature data, attic temperature data, humidity data, and/or air quality index data.

The fresh air cooling and ventilating system disclosed herein can have the flexibility to be installed in several different building structure environments to provide an energy and cost savings. For example, the fresh air cooling and ventilating system can be installed in a building structure without an air conditioning system, retrofitted to be installed in a building structure with an existing air conditioning system, or installed as part of a new air conditioning system installation.

Fresh Air Cooling and Ventilating System Installations

In some aspects, the fresh air cooling and ventilating system 100 can include a motorized fan or whole house fan (WHF) 102 mounted in an attic space 104 of a building structure 106. A motorized fan or whole house fan controller 200 can control operation of the motorized WHF 102, as described herein. A user device 201 as discussed herein, which can include or house for example a fresh air controller, can be mounted on an interior wall anywhere in the building structure 106, as shown. The user device 201 can be connected to and at least partially control the whole house fan controller 200 as discussed herein.

The user device 201 can include the fresh air controller 300 (FIGS. 2 and 3) as discussed herein. In some embodiments, the user device 201 can be a thermostat controlling the air conditioning system of the building as discussed herein. In some embodiments, the fresh air controller 300 can be in or be part of the thermostat controller as discussed herein (for example, as a separate controller in a thermostat device or be part of the thermostat controller itself in the thermostat controlling the air conditioning system). In some embodiments, the fresh air controller 300 can comprise the thermostat controller. In some embodiments, the thermostat controller can comprise the fresh air controller 300. In some embodiments, a control unit or device that controls the fresh air system 100 and/or building air condition system, such as the user device 201 or a thermostat control unit for controlling the building air condition system, can include the thermostat controller and/or the fresh air controller 300, with the thermostat controller and the fresh air controller 300 being separate controllers or being provided as a single, same controller in the control unit or device.

FIG. 1 depicts the fresh air cooling and ventilating system 100 operating to draw air into the building structure 106. The direction of air flow through the building is shown as flow lines 122 in FIG. 1. As shown in FIG. 1, the fresh air cooling and ventilating system 100 can include one or more WHFs 102 that are high-capacity fans that can rapidly draw a large volume of air out of the interior or living space 108. Outside air can be drawn into the interior space 108 through open windows 110 and/or damper 111 of the building structure 106 to replace the air that is drawn from the interior space 108 by the WHF 102.

As shown in FIG. 1, the building structure 106 can be a two-story building structure depicted with one or more WHFs 102, one or more windows 110, one or more dampers or air intakes 111, and/or one or more user devices 201. However, the type of building structure is not limiting, and the disclosed system can be used in, for example, a one, two, three, four, or any story residential home, apartment complexes, office buildings, and warehouses.

In some embodiments, the fresh air cooling and ventilating system 100 may use other types of devices such as dampers 111 installed on exterior walls of the building structure 106 that provide fluid communication between interior space 108 and the ambient environment.

In some embodiments, the dampers 111 can use or can have an air filter. In some embodiments, the dampers 111 do not use or do not have an air filter. In some embodiments, the dampers 111 do not have or do not include a motorized fan that draws air into the damper 111 from the environment to be directed into the interior space 108.

In some embodiments, the dampers 111 shown in FIG. 1 can be motorized automatic dampers that can be automatically opened and closed as discussed herein. The dampers 111 can be positioned in the exterior wall of the building structure 106 separating the interior space 108 from the ambient environment of the building structure 106. When open, the damper 111 can permit the flow of ambient air into the building structure 106 and when closed, can inhibit the flow of ambient air into the building structure 106. Motorized automatic dampers can be in connection with a fresh air controller 300. The fresh air controller 300 can control the operation of the motorized automatic dampers. In some embodiments, the fresh air controller 300 can send a command signal to close one or more or all of the automatic dampers in any of the operating modes or control logic flows discussed herein, including when sending a command signal to turn off the WHF 102 as discussed herein.

The motorized automatic dampers can open fully, close fully, or be positioned somewhere in between, for example, via a command signal from the fresh air controller 300. For example, in some embodiments, the motorized automatic dampers can open half way between fully closed and fully open, a quarter way between fully open and fully closed, or three quarters of the way between fully closed and fully open.

The fresh air cooling and ventilating system 100 shown in FIG. 1 depicts four dampers 111. In some embodiments, the fresh air cooling and ventilating system 100 can have 1, 2, 3, 4, 6, 12, 15, or more dampers 111. Any number of the dampers 111 can be motorized automatic dampers. For example, the fresh air cooling and ventilating system 100 can have 1, 2, 3, 4, 5, or more motorized automatic dampers. In some embodiments, one or more of the dampers 111 may be non-motorized and have one or more movable flaps or leafs that open under creation of negative pressure within the interior space 108 as discussed herein (for example, the WHF being activated) and that close with gravity, spring mechanisms, or other suitable mechanisms upon the WHF being stopped.

In some embodiments, the fresh air cooling and ventilating system 100 may use motorized automatic windows in combination with other types of devices such as skylights installed on the roof of the building structure 106 that provide fluid communication between interior space 108 and the ambient environment. In some embodiments, the fresh air cooling and ventilating system 100 may use other types of devices such as skylights installed on the roof of the building structure 106 that provide fluid communication between interior space 108 and the ambient environment.

In some embodiments, skylights can be motorized automatic skylights that can be automatically opened and closed as discussed herein. In some embodiments, the motorized automatic skylights can function similar to automated windows as discussed herein.

In some embodiments, the skylights can be positioned in the roof of the building structure 106 such as in location depicted by vents 114. The vents 114 depicted in FIG. 1 may represent skylights. The skylights may be positioned such that the skylights separate the interior space 108 from the ambient environment.

In some embodiments, the skylight may be a natural tubular skylight In some embodiments, the motorized automatic skylights can function similar to automated windows as discussed herein that has an air inlet 126 (e.g., a vent) to the ambient environment. When the WHF operates as discussed herein, the skylight, and in particular the air inlet 126 of the skylight, may function as an open window and/or damper as discussed herein to allow ambient air 107 into the interior space 108. When open, the vent of the skylight can permit the flow of ambient air 107 into the building structure 106 and when closed, can inhibit the flow of ambient air into the building structure 106. The air inlet 126 may be motorized to open and close and function similarly to an automated window as discussed herein. When the air inlet 126 is in an open position, the negative static pressure can draw outside air 107 into the building structure 106 as the exhaust 124 from the WHF 102 is expelled into attic of the building structure with air being drawn and directed through the air inlet 126, the duct 127, and air outlet 128. Operating the WHF 102 can create a positive static air pressure in the attic space 104, which can expel air 120 out of the building structure 106 to the outside through vents 114 located in the attic space 104.

The skylight 125 may be mounted in the attic 104 and connected to an air outlet 128 in the ceiling or wall separating the attic space 104 from the interior space 108 to create a negative static pressure in the interior space 108. The air outlet 128 can be an opening that allows ambient light into the interior space 108. In some embodiments, the air outlet 128 can be a diffuser, a register, or any other similar device. The skylight 125 can have a duct 127 connecting the air inlet 126 to the air outlet 128. The duct may be a tubular structure or reflecting tube that reflects and/or directs ambient light into the interior space 108.

In some embodiments, the duct 119 depicted in FIG. 1 may represent the tubular ducting of the skylight. The duct of the skylight may ricochet natural light into the interior space 108. The duct of the skylight may function as the duct 119 as discussed herein to provide fluid air communication between the exterior of the building structure 106 and the interior space 108 through the attic space 104.

In some embodiments, the skylights 126 may be a window-type of skylight installed in the roof of the building structure 106. When open, the skylight can permit the flow of ambient air into the building structure 106 and when closed, can inhibit the flow of ambient air into the building structure 106. The window-type of skylight may have a side that is pushed up/down or open to permit in ambient air into the interior space 108. The window-type of skylight may rotate on a hinge point to permit ambient air into the interior space 108. The window-type skylight may be motorized to open and close and function similarly to an automated window as discussed herein.

In some embodiments, the air inlet 126 in FIG. 1 can be or be at least partially replaced by the side of the window-type skylight that is pushed up/down or open to permit ambient air into the interior space 108. The duct 127 of the window-type skylight can be formed from surfaces or walls similar to that of the interior space 108 to create a flow path for ambient air between the air inlet 126 and air outlet 128, as well as permit ambient light into the interior space 108.

Motorized automatic skylights and/or air inlets 126 can be in connection with a fresh air controller 300. The fresh air controller 300 can control the operation of the motorized automatic skylights and/or air inlets 126. In some embodiments, the fresh air controller 300 can send a command signal to close one or more or all of the automatic skylights and/or air inlets 126 in any of the operating modes or control logic flows discussed herein, including when sending a command signal to turn off the WHF 102 as discussed herein.

The motorized automatic skylights and/or air inlets 126 can open fully, close fully, or be positioned somewhere in between, for example, via a command signal from the fresh air controller 300. For example, in some embodiments, the motorized automatic skylights can open half way between fully closed and fully open, a quarter way between fully open and fully closed, or three quarters of the way between fully closed and fully open.

In some embodiments, the fresh air cooling and ventilating system 100 can have 1, 2, 3, 4, 6, 12, 15, or more skylights. Any number of the can be motorized automatic skylights. For example, the fresh air cooling and ventilating system 100 can have 1, 2, 3, 4, 5, or more motorized automatic skylights. In some embodiments, one or more of the skylights may be non-motorized and be opened by the user manually.

In some embodiments, the fresh air cooling and ventilating system 100 can include one or more ventilation fans 118 as shown in FIG. 1. The ventilation fan 118 can be positioned in the attic space 104 of the building structure 106. The ventilation fan 118 can be positioned near or proximate to a corresponding vent 114 providing fluid communication between the attic space 104 and the ambient environment around the building structure 106. The ventilation fan 118 can be in communication with the fresh air controller 300 as discussed herein. In some embodiments, the ventilation fan 118 can draw air 120 from the attic space 104 through the vent 114 to facilitate the function of the WHF 102 as discussed herein. In some embodiments, the fresh air controller 300 can cause the ventilation fan 118 to operate with the WHF 102 being operated as discussed herein. In some embodiments, the fresh air controller 300 can operate the ventilation fan 118 independent of the WHF 102.

The ventilation fan 118 can be in communication with a ventilation fan or attic fan controller 224 (see for example FIGS. 2-5) which can control the operation of the ventilation fan 118 through a wired or wireless connection. In some embodiments, the ventilation fan controller 224 can be in communication with the fresh air controller 300 and receive a command/operation signal from the fresh air controller 300. The ventilation fan controller 224 can be connected to the fresh air controller 300 via a wireless and/or wired connection utilizing, for example, a Bluetooth connection, Wi-Fi connection, and/or any other connection suitable connection such as Ethernet cables. The fresh air controller 300 can send a command/operation signal causing the ventilation fan controller 224 to operate the ventilation fan 118 or to send a command/operation signal causing the ventilation fan controller 224 to cease operation of the ventilation fan 118. As discussed herein for the WHF 102 and the ventilation fan 118 can be operated at different speeds. The fresh air controller 300 can determine and select a desired speed for the ventilation fan 118 based on, for example, the speed of the WHF 102.

In some embodiments, the WHF 102 as discussed herein can be installed in place of the ventilation fan 118. The air inlet 112 and the WHF 118 installed in a vent 114 can be connected by a flexible, sound insulating duct 119. The duct 119 is illustrated in dashed lines in FIG. 1. In some embodiments, the WHF 118 can be used with or in an unvented or sealed attic (sometimes referred to as high-performance or conditioned attics). In an unvented attic, air-impermeable insulation is applied directly to the underside of the structural roof deck and is tied into the insulation located in the walls so that the roof system becomes part of the insulated building enclosure. In some embodiments, the WHF 118 can be used in an attic space 104 that is sealed with or without the duct 119.

The fresh air cooling and ventilating system 100 can be installed in several different heating, ventilation, HVAC (heating, ventilation, and air conditioning) and/or air conditioning building environments/systems to provide an energy savings and cost savings. Air conditioning system or air conditioning as used herein may include one or more systems of a building structure used for heating, cooling, ventilating, and/or any other type of conditioning/thermal management and/or movement of air within and/or through the building structure. In some embodiments, the fresh air cooling and ventilating system 100 can be installed in a building structure 106 without an existing air conditioning system. In such an installation, the fresh air controller 300 can make control decisions on whether to activate the fresh air cooling and ventilating system 100 based on the external and internal building temperature and/or humidity conditions. If the user device 201 has received an input or is set for cooling, the fresh air controller 300 can determine whether the outside air temperature is cooler than the inside and turns on the WHF (including opening windows or dampers if included). If the outside temperature is warmer than the internal temperature, the fresh air controller 300 does not activate the system 100 but can continue to monitor the temperature and/or humidity parameters periodically until the outside temperature is cool enough to cool effectively.

In some embodiments, the fresh air cooling and ventilating system 100 can be installed in a home with an existing air conditioning system. In a home with existing air conditioning, the fresh air controller 300 can control the air conditioner as well as the fresh air cooling and ventilating system 100. In such an installation, the fresh air controller 300 can use signals received from the internal and external temperature, humidity, and/or AQI sensors 230 to make control decisions about whether to activate either the fresh air cooling and ventilating system 100 or the existing air conditioning. If the user device 201 has received an input or is set for cooling, the fresh air controller 300 first can consider whether the fresh air cooling and ventilating system has the capacity to efficiently cool the building structure 106. As discussed herein, the fresh air controller 300 can send a signal to activate the fresh air cooling and ventilating system 100 over the existing air conditioning whenever the ambient temperature and humidity conditions allow in order to realize a cost and energy savings over running the air conditioner. The fresh air controller 300 can be set to default to use the fresh air cooling and ventilating system 100 whenever possible instead of the air conditioning system to provide a cost savings. If the fresh air controller 300 determines that the fresh air cooling and ventilating system 100 can effectively cool the building structure, the fresh air controller 300 can send a signal to activate the fresh air cooling and ventilating system 100 until the desired temperature is reached. If, while the WHF 102 is running, the fresh air controller 300 determines that the WHF 102 is providing inadequate cooling and cannot cool the building structure 106 to the desired temperature, it can send a command/operation signal to the whole house fan controller 200 to turn off the WHF 102 and can turn on the air conditioner. The fresh air controller 300 then can continue to monitor the situation and can send a command/operation signal to the thermostat to turn off the air conditioner and send a command/operation signal to the whole house fan controller 200 to turn back on the WHFs 102 when conditions are optimal for the fresh air cooling and ventilating system 100.

In some embodiments, the fresh air cooling and ventilating system can be installed in a building as part of a new air conditioning installation. In such an installation, the user device 201 functions substantially the same as in installations retrofitted to function with existing air conditioning systems. The user device 201 may also fully control the operation of the air conditioning system, in particular when the system 100 installed as part of a new air conditioning installation.

The fresh air controller 300 can analyze data (for example, API data) to more efficiently operate the system 100 and increase the automation of the system 100. The data utilized by the system 100 either can be generated locally within a single fresh air cooling and ventilating system or can come from a larger set of fresh air cooling and ventilating systems provided to the fresh air controller 300 via an internet connection through cloud services 204. In some embodiments, data analysis can occur remotely from the fresh air controller 300. Data can be collected and analyzed through a cloud based online system, formatted for use by a fresh air controller 300, then transmitted to the fresh air controller 300 via the internet through cloud services 204. For example, in some embodiments, the fresh air controller 300 could utilize historical usage data to determine patterns of usage and predict when a user may want to use the system 100. In some embodiments, usage and weather data can be combined to determine when a particular user is or set of users are most likely to utilize the fresh air cooling and ventilating system 100.

In some embodiments, the recommended usage in the summer season is to turn on the fresh air cooling and ventilating system 100 when the outside temperature is equal to or below the inside temperature and then keep them on until late in the evening to remove most of the latent heat that can be stored in the structure and mass of the building structure and/or the attic. In some embodiments, the system 100 can be kept on until three hours after sunset. In some embodiments, the system 100 can be kept on three or more hours, including 4, 5, 6, 7, or 8 or more hours, including being kept on all night. This method can prolong the cooling effects of the fresh air cooling and ventilating system 100 into the subsequent day, thus reducing demand of the air conditioner. By following this procedure, a typical building structure in a desert climate zone, such as in the Inland Empire area of Southern California, may only need the air conditioner to be run for two to three hours per day instead of the normal 8 to 10 hours in the heat of the summer typically required by existing air conditioning systems. The fresh air cooling and ventilating system 100 may use a fraction of the energy of the air conditioning system, and therefore results in a significant energy and cost savings compared to traditional air conditioning systems.

In some embodiments, the fresh air controller 300 can be in two-way communication with a smart phone or device application 220. The fresh air controller 300 can be in wireless communication with the smart phone application 220 using Bluetooth, Wi-Fi, and/or any other suitable wireless communication protocol to send and receive communication signals. Such communication protocols may be used when the user with the smart phone or other smart device is in or proximate the building structure having the system 100.

In some embodiments, the smart phone application 220 can be in two-way communication with the fresh air controller 300 through the cloud services 204 to provide one or more of the control functions discussed herein. The smart phone application 220 can utilize cloud services 204 when the user with the smart phone or other smart device is not in or proximate the building structure having the system 100. For example, when the user is not within Bluetooth or Wi-Fi range of the fresh air controller 300, the smart phone application 220 may connect to fresh air controller 300 through the cloud services 204. The smart phone application 220 may also connect to the cloud services 204 to send and receive communication signals with the fresh air controller 300 even when in range for Bluetooth or Wi-Fi communication with the fresh air controller 300. The fresh air controller 300 is in communication with the cloud services 204 as discussed herein, allowing for communication with the smart phone application 220 through the cloud service 204.

As used herein, a smart phone or device application 220 can be used with any portable electronic device, such as a smart phone or tablet. The smart phone application 220 can allow a user to view information about and input information/commands to the fresh air cooling and ventilating system 100 and operate the system 100. The fresh air controller 300 and/or any other parts of the system 100 can receive control inputs or a command signals from the smart phone application 220. For example, smart phone application 220 can be used to turn on and off the system 100, open and close windows 228A-C, switch the modes of operation of the system 100, turn on or off the WHF 102, turn on or off the ventilation fan 118, and/or any other operation that the fresh air controller 300 can perform as discussed herein. Such integration through smart phone application 220 allows for easier use of the system 100.

As shown in FIG. 2, in some embodiments, the smart phone application 220 can be in two-way communication with the automatic windows 228A-C. The smart phone application 220 can control the operation of the automatic windows 228A-C without the use of the fresh air controller 300. For example, the user may use the smart phone application 220 to open or close the automatic windows 228A-C to provide fresh air to the interior space 108 without the fresh air system 100 operating or running, such as the WHF 102 not operating or running.

As shown in FIG. 2, in some embodiments, the smart phone application 220 can be in two-way communication with the ventilation fan controller 224. The smart phone application 220 can control the operation of the attic ventilation fan 118 through the ventilation fan controller 224 without the use of the fresh air controller 300. For example, the user may use the smart phone application 220 to vent the attic space 104 without the fresh air system 100 operating or running, such as the WHF 102 not operating or running.

In some embodiments, the smart phone application 220 can be used to set the speed of the WHF 102 based on the temperature within the interior space 108. For example, the smart phone application 220 can be used to set a WHF to operate at low speed when the temperature in the interior space 108 is 70° F. to 75° F. or 65° F. to 75° F., to operate at high speed when the temperature in the interior space 108 is above 75° F., and to turn off when the temperature in the interior space 108 is below 65° F. The system 100 can be programmed that if the inside temperature warms from 65° F. to 66° F., the WHF 102 will turn on at low speed. Each WHF 102 controlled by the smart phone application 220, web application 236, smart home connection 208, and/or user device 201 can have controls for fan speed, timer mode, display mode, and temperature set points. The smart phone application 220, web application 236, smart home connection 208, and/or user device 201 can have a speed control that allows the selection of a speed on a multi-speed (e.g., 2-speed or 3-speed) WHF 102. The smart phone application 220, web application 236, smart home connection 208, and/or user device 201 can allow a user to select the duration (e.g., 12 hours) of the timer. The smart phone application 220, web application 236, smart home connection 208, and/or user device 201 can allow a user to select to operate the WHF 102 in continuous on mode. The smart phone application 220, web application 236, smart home connection 208, and/or user device 201 can allow a user to select modes of operation as discussed herein, for example with reference to FIGS. 8-13.

The smart phone application 220, web application 236, smart home connection 208, and/or user device 201 can perform a factory reset on the fresh air controller 300 and/or other components of the system 100 discussed herein. The smart phone application 220, web application 236, smart home connection 208, and/or user device 201 can initiate or coordinate the pairing process for pairing devices. For example, the one or more automatic windows 228A-C and/or smart home devices may be initially paired with the system 100 via the smart phone application 220, web application 236, smart home connection 208, and/or user device 201. The smart phone application 220, web application 236, smart home connection 208, and/or user device 201 can allow a user to configure the system to automatically open select automatic windows when the WHF 102 is turned on. The smart phone application 220, web application 236, smart home connection 208, and/or user device 201 can allow a user to select how far to open particular windows. The smart phone application 220, web application 236, smart home connection 208, and/or user device 201 can allow a user to select the ventilation fan 118 to turn on and at what speed when the WHF 102 is turned on.

As shown in FIG. 2, the fresh air controller 300 can send a push notification 216 to the smart phone application 220, via cloud service 204 and/or API connections 212, alerting the user with various information about the system 100. In some embodiments, the push notification service 216 may be associated and depend on information from API connections 212. For example, the smart phone application 220 may receive information from API connections 212 as discussed herein without the fresh air controller 300 providing such information. The push notification service or push notification 216 may include a push notification on the smart phone application 220 based on the information from the API connections 212. In some embodiments, the web application 236, smart home connection 208, and/or user device 201 can utilize the push notification service 216 as discussed herein directly in connection with the push notification service 216 or cloud services 204 to provide push notification or prompts as discussed herein.

A push notification 216 can be an alert that a smart phone application 220 displays to the user via a smart phone or device. For example, the fresh air controller 300 can send a push notification 216 to the user indicating it is an ideal time to run the system or WHF, the system or WHF is running, the system or WHF is turning on, or the system or WHF is turning off, or any other information about the system as discussed herein. Push notifications 216 can prompt the user for input. For example, in some embodiments, the fresh air controller 300 can prompt a user with a question such as “is there a window open in the home?” through a push notification 216.

In some embodiments, the fresh air controller 300 can send a push notification 216 or prompt to the smart phone application 220, web application 236, smart home connection 208, and/or the user device 201.

Fresh Air Cooling and Ventilating System Operating Modes and Controls

FIG. 7 depicts an embodiment of a control diagram of the logic for controlling the fresh air cooling and ventilating system 100. FIG. 7 depicts a control diagram of the logic the fresh air controller 300 can utilize when the user places the fresh air cooling and ventilating system 100 in an automatic mode using, for example, the smart phone application 220, web application 236, smart home connection 208, and/or user device 201. In some embodiments, the logic depicted in FIG. 7 can run iteratively at a range of different intervals including every minute, every five minutes, every 10 minutes, every 30 seconds, every 1 second, anytime in between, or anytime beyond 10 minutes. The interval at which the fresh air controller 300 can operate the control logic can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.

As depicted in FIG. 7, in some embodiments, fresh air controller 300 can first determine whether the WHF 102 of the fresh air cooling and ventilating system 100 is already operating, running, activated, or turned on 701. In some embodiments, depending on whether the WHF is operating in step 701, the fresh air controller 300 will follow either a WHF on logic flow path 703 or a WHF off logic control flow path 702.

As depicted in FIG. 7, in some embodiments, if the fresh air controller 300 determines that WHF is already operating in step 701, the fresh air controller 300 can proceed to step 715. For step 715 in the WHF on logic flow path 703, the fresh air controller 300 can determine whether the temperature in the attic of the building structure is within the operating parameters of the system. The fresh air controller 300 can receive a temperature value corresponding to the temperature in the attic of the building structure from a temperature sensor located in the attic of the building structure. The fresh air controller 300 can compare the attic temperature value with a predetermined attic temperature value. The fresh air controller 300 can determine that if the attic temperature is higher than the predetermined attic temperature value, the fresh air controller 300 can send a command/operation signal causing the whole house fan controller to turn off the WHF 102 and signal the automatic windows to close, as shown in step 785. The fresh air controller 300 can determine that if the attic temperature value is below the predetermined attic temperature, the fresh air controller 300 can continue on the WHF on logic flow path 703 to step 725.

The predetermined attic temperature, in some embodiments, can be 182 degrees Fahrenheit. A temperature of 182 degrees Fahrenheit or above may indicate that there is a fire in the building structure. In such a scenario the fresh air cooling and ventilating system 100 is designed to shut down to prevent air from being drawn into the building structure and further feeding any fire that may be occurring in the building structure. The predetermined attic temperature is not limited to 182 degrees Fahrenheit, but can be set at any temperature value, including 160, 165, 170, 170, and 180 degrees Fahrenheit. For example, under typical operating conditions, the attic temperature may reach between 120 and 140 degrees Fahrenheit.

For building structures positioned in excessively hot conditions, such as a desert, the attic temperature may reach up to 160 degrees Fahrenheit. In some embodiments, the smart phone application 220, web application 236, smart home connection 208, and/or user device 201, can allow the user to modify the predetermined attic temperature, for example, depending on the location of the system 100. The system 100 may automatically modify the predetermined attic temperature depending on the location of the building structure within which the system 100 is installed. This feature is advantageous because it can prevent the system from exacerbating a fire that may be occurring in the building structure.

In some embodiments, as depicted in FIG. 7, if the attic temperature is determine to be lower than the predetermined attic temperature in step 715, the fresh air controller 300 can determine whether the outside air quality index value is within predetermined parameters for operation of the fresh air cooling and ventilating system 100 as shown in step 725. In some embodiments, the fresh air controller 300 can receive an air quality index value corresponding to the air quality index for the ambient air outside the building structure through a smart home connection 208, API connection 212, sensors 230, and/or over the internet as discussed herein. The fresh air controller 300 can compare the air quality index value for the ambient air outside the building structure to a predetermined operating parameter for the air quality index.

In some embodiments, the predetermined operating parameters for air quality index value or predetermined air quality index value can be set by the user via the smart phone application 220, web application 236, smart home connection 208, and/or user device 201. In some embodiments, the predetermined operating parameters for the air quality index can be set by the manufacturer, the installer, or some other entity during or prior to installation of the system 100. In some embodiments, the predetermined air quality index value can be 100. In some embodiments, the predetermined air quality index value can be 50, 60, 70, 80, 90, 110, 120, 130, 140, or 150. It is advantageous to check the air quality index value of the ambient air outside the building structure prior to operating the WHF because operating the WHF when the air quality index is high may cause highly polluted air to be pulled into the building structure, potentially negatively affecting its occupants.

In some embodiments, as depicted in FIG. 7, if the air quality index value is determined to be outside the air quality index operating parameters such as being greater than the predetermined air quality index value, the fresh air controller 300 send a command signal to turn off the WHF 102 and send a command signal to close the automatic windows as shown in step 785.

In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines that air quality index value is within the air quality index operating parameters such as being less than the predetermined air quality index value in step 725, the fresh air controller 300 can determine whether the outside humidity is within the parameters for operation as shown in step 735. The fresh air controller 300 can receive a humidity value corresponding to the humidity of the ambient air outside the building structure. In some embodiments, the fresh air controller 300 can receive the ambient humidity value from a smart home connection 208, API connection 212, sensors 230, and/or through the internet or from a humidity sensor in communication with the fresh air controller 300.

In some embodiments, the fresh air controller 300 can compare the ambient air humidity value to a predetermined humidity operating parameter or value. In some embodiments, the predetermined humidity operating parameter can be set by the user utilizing the user device, smart phone application, smart home connection, and/or web application, or by the manufacturer or the system or the person installing the system or any combination of the above.

In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines that the ambient air humidity value and the predetermine humidity operating parameters is outside the predetermined humidity operating parameters such as the humidity value being greater than the predetermined humidity value, the fresh air controller 300 can send a signal to turn off the WHF 102 and send a command signal to close the automatic windows as show in step 785. In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines that the ambient air humidity value is within the operating parameters such as humidity value being less than the predetermined humidity value, the fresh air controller 300 continues to the next step in the WHF on flow path 703 to step 735.

In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines the ambient air humidity value to be within the operating parameters in step 735, the fresh air controller 300 can determine whether the outside air temperature is within the parameters for operation in step 745. The fresh air controller 300 can receive an ambient air or outside temperature value corresponding to the temperature of the air outside the building structure. In some embodiments, the fresh air controller 300 can receive an ambient air or outside temperature value from a temperature sensor in communication with the fresh air controller 300. In some embodiments, the fresh air controller 300 can receive an ambient air or outside temperature value from a smart home connection 208, API connection 212, sensors 230, and/or over the internet to a weather service.

In some embodiments, the fresh air controller 300 can compare the present or current outside temperature value to a predetermined ambient temperature operating parameter. In some embodiments, the predetermined ambient temperature operating parameter can be set by the user utilizing the user device, smart phone application, smart home connection, and/or web application, or by the manufacturer or the system of the person installing the system or any combination of the above.

In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines that the present ambient air or outside temperature value is not within the predetermined ambient temperature operating parameters such as the present or current ambient air or outside temperature value is greater than the predetermined outside temperature value in step 745, the fresh air controller 300 send a command signal to turn off the WHF 102 and send a command signal to close the automatic windows as shown in step 785. In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines that the outside temperature value is within the operating parameters such as the present or current ambient air or outside temperature value is less than the predetermined outside temperature value, the fresh air controller 300 continues to the next step in the WHF on flow path 703, step 755.

In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines that the outside air temperature value is within the operating parameters in step 745, the fresh air controller 300 can determine whether the air temperature inside the building structure (inside temperature value) is higher than the air temperature outside the building structure (outside temperature value) as shown in step 755. The fresh air controller 300 can receive a temperature value corresponding to the temperature of the air inside the building structure (inside temperature value) from a smart home connection 208, API connection 212, sensors 230. In some embodiments, the fresh air controller 300 can receive a temperature value corresponding to the temperature of the ambient air outside the building structure (outside temperature value) from a smart home connection 208, API connection 212, sensors 230. In some embodiments, the fresh air controller 300 can receive the inside temperature value from a temperature sensor in communication with the fresh air controller 300.

In some embodiments, the fresh air controller 300 can compare the inside temperature value to the outside temperature value. If the fresh air controller determines that the outside temperature value is greater than the inside temperature value in step 755, the fresh air controller 300 send a command signal to turn off the WHF 102 and send a command signal to close the automatic windows as shown in step 785. In some embodiments, as depicted in FIG. 7, if fresh air controller 300 determines that the outside temperature value is less than the inside temperature value, the fresh air controller 300 can continue to the next step in the WHF on flow path 703 to step 765.

In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines the inside temperature value is greater than the outside temperature value in step 755, the fresh air controller 300 can determine whether the outside air temperature has increased by more than 1 degree Fahrenheit, as shown in step 765. The fresh air controller 300 can compare the current or present outside temperature value to a stored previous outside temperature value.

In some embodiments, the stored previous outside temperature value can correspond to the outside temperature received by the fresh air controller 300 during the most recent iteration of the WHF off control logic flow path 702. In some embodiments, the stored previous outside temperature value can correspond to the outside temperature received by the fresh air controller 300 during the most recent iteration of the WHF on control logic flow path 703. In some embodiments, change in temperature is not limited to 1 degree Fahrenheit and the fresh air controller 300 can determine whether the outsider temperature has increased by more than 2 degrees Fahrenheit, 3 degrees Fahrenheit, 5 degrees Fahrenheit, or any other temperature increase.

In some embodiments, if the fresh air controller 300 determines there has been an increase in the outside temperature of more than 1 degree Fahrenheit in step 765, the fresh air controller 300 send a command signal to turn off the WHF 102 and send a command signal to close the automatic windows as shown in step 785. In some embodiments, the fresh air controller can delete or clear the stored previous temperature value in step 785. In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines there has not been an increase in the outside temperature of more than 1 degree Fahrenheit the fresh air controller 300 can continue to the next step in the WHF on flow path 703 to step 775.

In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines that the outside temperature has not increased by more than one (1) degree Fahrenheit or any other predetermined temperature increase in step 765, the fresh air controller 300 can adjust the WHF 102 speed based on the inside temperature value, as shown in step 775. The fresh air controller 300 can compare the previously determined inside temperature value to a set of predetermined inside temperature values.

In some embodiments, the fresh air controller 300 can send a command/operation signal causing the whole house fan controller 200 to adjust the WHF speed based on the inside temperature value, as shown in step 775. The fresh air controller 300 can send a command/operation signal causing the whole house fan controller 200 to adjust the WHF speed as discussed herein.

In some embodiments, the fresh air controller 300 can compare the inside temperature value to a first, second, and third predetermined inside temperature values. For example, if the inside temperature value is between the first and second predetermined inside temperature values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a first speed. If the inside temperature value is between the second and third predetermined inside temperature values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a second speed. If the inside temperature value is greater than the third predetermined inside temperature value, the fresh air controller 300 can send a command signal to operate the WHF 102 at a third speed.

In some embodiments, the first, second, and third fan speeds correspond to a low, a medium, and a high speed respectively. In some embodiments, the WHF is not limited to three speeds, but instead can have 1 speed, 2 speeds, 4 speeds, 6 speeds, or any number of speeds. In some embodiments, the number of speeds corresponds to the number of predetermined values to which the fresh air controller 300 can compare the inside temperature of the building structure such that, for example, the number of speeds is equal to the number of predetermined temperature values.

In some embodiments, the first predetermined inside temperature to which the fresh air controller 300 can compare the inside temperature to is the lowest predetermined temperature. In some embodiments, the fresh air controller 300 can send a command signal to turn off the WHF and close the automatic windows when the inside temperature value is lower than the lowest predetermined inside temperature value. In some embodiments, the first predetermined inside temperature can be the predetermined inside temperature value for WHF operation discussed herein with reference to step 760. In some embodiments, the predetermined inside temperature values to which the inside temperature is compared to can be set by the user utilizing the user device, smart phone application, smart home connection, and/or web application, or by the manufacturer or the system of the person installing the system or any combination of the above. This can help to not turn on, activate, or keep running the WHF if the building structure is already cooler than the user would like it to be.

In some embodiments, when the fresh air controller 300 determines that the WHF 102 should be turned off while progressing through the WHF on logic flow path 703, the fresh air controller 300 can delete or clear the store outside temperature value as part of step 785. In some embodiments, as part of step 785 for any of the logic steps discussed herein, the fresh air controller 300 can send a signal to the home thermostat to resume or continue operation of the air conditioning system when it is not ideal to run the WHF.

In some embodiments, when the fresh air controller 300 sends a signal to close the automatic windows, as shown in step 785, the fresh air controller 300 can perform a check to determine or verify whether the automatic windows have been closed. The fresh air controller 300 can perform this check by determining the number of automatic windows connected to the fresh air controller 300 or the system 100. The fresh air controller 300 can retrieve or receive a status signal from each window indicating whether or not the any of the particular window(s) are open. If one or more of the windows are open, the fresh air controller 300 can send a command signal to close the corresponding window. If all of the windows are closed, the WHF on control logic flow path 703 can be complete. If the fresh air controller 300 receives a signal indicating there is an error with one or more windows that cannot be closed automatically, the fresh air controller 300 can cause an error notification to be sent to the user through a push notification 216 or prompt sent via the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201 indicating that one or more particular windows could not closed automatically. If there is more than one automatic window connected to the system, the fresh air controller 300 can repeat the same steps for each automatic window.

In some embodiments, the when the automatic mode is turned off manually from either the switch 432, the user device 201, smart phone application 220, smart home connection 208, and/or web application 236, the fresh air controller 300 can clear the stored outside temperature value, send a command signal to close the automatic windows, and verify the automatic windows are closed as discussed herein.

As depicted in FIG. 7, in some embodiments if at the fresh air controller 300 determines the WHF is not running in step 701, the fresh air controller 300 can follow the logic of the WHF off control flow path 702. In some embodiments, as depicted in FIG. 7, the logic of flow path can be the same or similar to the logic of the WHF on flow path 703 up until step 760. Thus, steps 710, 720, 730, 740, and 750 can correspond to steps 715, 725, 735, 745, and 755 described above, respectively. The fresh air controller 300 can perform steps 710, 720, 730, 740, and 750 in substantially the same manner as described above for steps 715, 725, 735, 745, and 755, respectively, with steps 710, 720, 730, 740, and 750 leading to step 792 or continuing in the logic sequence to, for example, step 790 similar to steps 715, 725, 735, 745, and 755, leading to step 785 or continuing in the logic sequence to, for example, step 775 as discussed herein.

After determining that the inside temperature is greater than the outside temperature in step 750, in some embodiments, as depicted in FIG. 7, the fresh air controller 300 can determine whether the present or current inside temperature value is greater than a predetermined inside temperature value for operation of the WHF as shown in step 760 on the WHF off logic flow path 702. The fresh air controller 300 can compare the inside temperature value to a predetermined inside temperature value for operation. The predetermined inside temperature value for operation can be set by the user utilizing the user device, smart phone application, smart home connection, and/or web application, or by the manufacturer or the system of the person installing the system or any combination of the above. This feature allows setting a minimum temperature below which the WHF is not activated, thus preventing the building structure from getting too cold. The predetermined inside temperature value can equal or correspond to the minimum temperature below which the WHF is not activated or turned on.

In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines that the present or current inside temperature value is less than the predetermined inside temperature value in step 760, the fresh air controller 300 will not send a command signal to turn on or activate the WHF 102 or open the automatic windows, as shown in step 792. If the fresh air controller 300 determines that the present or current inside temperature value is greater than the predetermined inside temperature value in step 760, the fresh air controller 300 can proceed to the next step in the WHF off logic flow path 702 to step 770.

In some embodiments, as depicted in FIG. 7, if the fresh air controller 300 determines that the inside temperature value is greater than the predetermined inside temperature value in step 760, the fresh air controller 300 can send a command signal to not operate or activate to a home or other system connected thermostat(s) that can control air condition system(s) of the building structure, as shown in step 770. The fresh air control 300 can send a command signal to one or more connected thermostats as discussed herein to set the operating mode to off, for example, for an air conditioning system. The fresh air controller 300 can verify that the connected thermostat(s) are in the off mode. In some embodiments, the connected thermostat(s) are set to an off mode to prevent the air conditioning system in the building structure from operating at the same time as the WHF.

In some embodiments, as depicted in FIG. 7, after setting the connected thermostats to off in step 770, the fresh air controller 300 can send a command signal to the automatic windows connected to the fresh air cooling and ventilating system 100 to open, as shown in step 780. The fresh air controller 300 can verify whether the automatic windows opened. If the fresh air controller 300 determines in step 780 the automatic windows did not open as discussed herein, the fresh air controller 300 can send an error message to the user via a push notification or prompt sent to the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201. In some embodiments, the fresh air controller 300 in the automatic mode will not turn on the WHF 102 if the fresh air controller 300 cannot verify that at least one window is open, as shown in step 792.

In some embodiments, to verify or check that at least one automatic window is open in step 780, the fresh air controller 300 can determine the number of automatic windows connected to the fresh air controller 300 or the system 100. The fresh air controller 300 can determine whether the first automatic window is set to automatically open. If the first automatic window is set to automatically open, the fresh air controller 300 can send a signal to open the first automatic window. The fresh air controller 300 can request the status of the first automatic window and can receive a signal indicating whether the first automatic window is open, closed, or is experiencing an error. If first automatic window is closed or experiencing an error, the fresh air controller 300 can send a push notification or prompt, via the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201, alerting the user of the error and turn off or exit automatic mode. If there are multiple or one or more automatic windows, the fresh air controller 300 can repeat this process for each automatic window and can activate the WHF if at least one automatic window is open. If all of the automatic windows are closed or experiencing an error, the fresh air controller 300 can turn off or exit automatic mode, while having sent a push notification or prompt, via the smart phone application 220, the web application 236, smart home connection 208, or the user device 201, alerting the user of the error based on the closed or error automatic window logic as discussed herein. In some embodiments, if the fresh air controller 300 verifies at least one window is open in step 780, the fresh air controller 300 can send a signal to the whole house fan controller 200 turn on, activate, or operate the WHF and adjust the WHF speed, as shown in step 790.

In some embodiments, the system 100 can be communication with an alarm system of the building structure. The alarm system of the building structure can be designed to monitor the building structure and inform when an intruder has entered the building structure or some other undesirable event has occurred when the alarm system is active or activated (e.g., armed). The fresh air controller 300 can send and receive communication signals to and from the alarm system. In some embodiments, the fresh air controller 300 can be in communication with the alarm system or a controller of the alarm system through the smart home connections 208, including via the cloud services 204, as discussed herein.

In some embodiments, when the alarm system is active, the alarm system or alarm system controller can send a communication or status signal to the fresh air controller 300 indicating that alarm system is active and that the one or more automatic windows of the building structure should not be opened. In some embodiments, when the alarm system is active and the user controls the system 100 to operate and open the one or more automatic windows as discussed herein (e.g., in the semi-automatic mode(s)), the fresh air controller 300 can send a push notification 216 to the smart phone application 220, via cloud service 204 and/or API connections 212, alerting the user that the alarm system is active and that the one or more automatic windows should not be open or that opening the one more automatic windows may trigger the alarm system. In some embodiments, when the alarm system is active and the system 100 is automatically operating (e.g., in the automatic mode(s)) where one or more automatic windows are to be automatically opened as discussed herein, the fresh air controller 300 can send a push notification 216 to the smart phone application 220, via cloud service 204 and/or API connections 212, alerting the user that the alarm system is active and that the one or more automatic windows could not be opened or that opening the one more automatic windows may trigger the alarm system.

The system 100 may configured such that the user may override the functionality or setting of automatic windows not being able to be opened when the alarm system is active to have automatic windows be opened by the fresh air controller 300 even if the alarm system is active. The fresh air controller 300 may send a status signal to the alarm system indicating user override for opening automatic windows. In some embodiments, the alarm system may include functionality (e.g., with the fresh air controller 300 sending an override signal) to allow the fresh air controller 300 to open one or more automatic windows without triggering the alarm system while the alarm system is active.

In some embodiments, when the alarm system is active, the fresh air controller 300 can suspend operation of the WHF and not open the one or more windows in one or more modes discussed herein that cause the automatic windows to automatically open (e.g., in the automatic mode(s)) where the fresh air controller 300 monitors certain parameters whether to automatically open one or more automatic windows and turn on the WHF). In some embodiments, when the alarm system is inactive or deactivated (e.g., disarmed), the alarm system or alarm system controller can send a communication or status signal to the fresh air controller 300 indicating that alarm system is inactive and that the one or more automatic windows of the building structures can be opened for, for example, the system 100 to operate as discussed herein. When the alarm system is activated, the alarm system can send an active status signal to the fresh air controller 300; if the WHF is operating with one or more automatic windows open (in any mode), the fresh air controller 300 may in response suspend operation of the WHF and close one or more automatic windows as discussed herein to, for example, secure the building structure 106.

In some embodiments, the fresh air controller 300 can send a command/operation signal causing the whole house fan controller 200 to adjust the WHF speed based on the inside temperature value, as shown in step 790. The fresh air controller 300 can send a command/operation signal causing the whole house fan controller 200 to adjust the WHF speed as discussed herein in reference to step 775.

In some embodiments, after turning on the WHF according to the WHF off logic flow path 702 discussed herein, the fresh air controller 300 can generate and store a stored outside temperature value corresponding to the outside temperature value received by the fresh air controller 300 during this iteration of the flow path 702, such as at step 740 as discussed herein or after performing step 790 with the WHF operating. The stored outside temperature value can correspond to a previous temperature value for use in the control logic in any of the modes discussed herein. The previous temperature value can be associated with a time period ago between the current iteration of the logic flow path and the next time the fresh air controller 300 generates and stores a stored outside temperature value as discussed herein. In some embodiments, the time period ago can be a predetermined time period ago, a previous time period, or a predetermined previous time period corresponding to a time when the fresh air controller 300 retained the stored/previous outside temperature value.

FIGS. 8, 9A, 9B 10, and 11 depict embodiments of a control diagram of the logic for controlling the fresh air cooling and ventilating system 100. FIGS. 8, 9A, 9B, 10, and 11 depict embodiments of the fresh air cooling and ventilating system 100 operating in a semi-automatic mode. The semi-automatic mode can include control logic that runs certain aspects of the system 100 automatically after the user provides inputs for other aspects, such as turning on the system 100.

FIG. 8, depicts an embodiment of control logic when the fresh air cooling and ventilating system 100 is turned on and is set to operate in the semi-automatic mode by a user with the system 100 including automatic windows. The control logic illustrated in FIG. 8 can be implemented when the system 100 is initiated or controlled in the semi-automatic mode from the user device 201, smart home connections 208, and/or webpage application 236. In some embodiments, the control logic illustrated in FIG. 8 can be implemented when the system 100 is initiated or controlled in the semi-automatic mode from the smart phone application 220. The control logic illustrated in FIG. 8 can run iteratively at a range of different intervals including every minute, every five minutes, every 10 minutes, every 30 seconds, every 1 second, anytime in between, or anytime beyond 10 minutes. The interval at which the fresh air controller 300 can operate the logic can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.

In fresh air control logic diagram depicted in FIG. 8, steps 801, 815, 825, 835, and 845 can correspond to steps 701, 715, 765, 775, and 785, respectively, described herein for FIG. 7. The fresh air controller 300 can perform steps 801, 815, 825, 835, and 845 in substantially the same manner as described above for steps 701, 715, 765, 775, and 785, respectively, with steps 815, 825, and 835 leading to step 845 or continuing in the logic sequence to, for example, step 835, similar to steps 715, 765, and 775 leading to step 785 or continuing in the logic sequence to, for example, step 775 as discussed herein.

In the fresh air control logic diagram depicted in FIG. 8, steps 810, 820, 840, 860, 870, and 880 can correspond to steps 710, 720, 760, 780, 790, and 792, respectively, described herein FIG. 7. The fresh air controller 300 can perform steps 810, 820, 840, and 860 in substantially the same manner as described above for steps 710, 720, 760, and 780, respectively, with steps 810, 840, and 860 leading to step 880 or continuing in the logic sequence to, for example, step 870, similar to steps 710, 760, and 780 leading to step 792 or continuing in the logic sequence to, for example, step 790 as discussed herein.

For the WHF off logic flow path 802, in some embodiments, the fresh air controller 300 can send a command signal to cause the WHF to operate for a predetermined amount of time immediately after determining the attic temperature is within parameters for operation per step 810. After the WHF runs for the predetermined amount of time, the fresh air controller 300 may proceed to step 820 to continue the control logic as discussed herein. In some embodiments, the predetermined amount of time for operation of the WHF can be 30 minutes. In some embodiments, the predetermined amount of time for operation can be 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, or greater than 60 minutes.

As depicted in FIG. 8, some steps of the control logic for controlling the system 100 have a similar first step 801 to the embodiment illustrated in FIG. 7. In some embodiments, as depicted in FIG. 8, the fresh air controller 300 may check certain operating parameters after determining whether the WHF is already running, as shown in step 801, and following the WHF on flow path 803. For example, as depicted in FIG. 8, in some embodiments, the fresh air controller 300 may determine whether the attic temperature is with operating parameters, as shown in step 815, and whether the outside temperature has increased by more than one degree Fahrenheit, as shown in step 825. In some embodiments, as depicted in FIG. 8, after determining the attic temperature is within operating parameters, as shown in step 815 and that the outside temperature has not increased by more than one degree Fahrenheit, the fresh air controller 300 can proceed to adjusting the WHF speed based on the temperature inside the living space, as shown in step 835. In some embodiments, as depicted in FIG. 8, after determining the attic temperature is not within operating parameters, as shown in step 815, or that the outside temperature has increased by more than one degree Fahrenheit, the fresh air controller 300 can send a signal to the whole house fan controller 200 to turn off the WHF and send a signal to close the automatic windows as shown in step 845.

In some embodiments, the when the semi-automatic mode is turned off manually by the user from the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201, the fresh air controller 300 can clear the stored outside temperature value, send a signal to close the automatic windows, and verify the windows are closed as discussed herein.

In some embodiments, as depicted in FIG. 8, when determining whether the outside air quality index value is within operating parameters on the WHF off flow path 802, as shown in step 820, the fresh air controller 300 can send a push notification or prompt, via the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201, to the user if the air quality index is not within operating parameters as discussed herein (for example, for step 725), as shown in step 830. The push notification or prompt can warn, alert, or inform the user that it is not preferable to operate the WHF. After sending the push notification or prompt notifying that it is not preferable to operate the WHF, the fresh air controller may proceed step 840 to determine whether to turn the WHF on, activate, or operate based on the inside temperature. By providing for the WHF to possibly operate as discussed herein after step 830, the user may be provided with greater control over the system 100 and choice as to when to operate the fresh air cooling and ventilating system 100, despite for example, possibly an undesirable air quality index value as discussed herein.

In some embodiments, a push notification or prompt that does not turn off the WHF or prevent the system from operating can be added, in some embodiments, at any decision point of the fresh air controller 300 whether in the WHF on flow path or the WHF off flow path, or any other logic flow path utilized by the fresh air controller 300. For example, in some embodiments, when the WHF is on or when the WHF is off, the fresh air controller 300 may send a push notification or prompt, via the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201, alerting the user that the outside humidity is high and that it is not preferable to operate the WHF, but nonetheless, still allow the user to continue operation of the WHF.

Returning to the WHF off logic flow path 802, in some embodiments, the fresh air controller 300 can allow the user to set whether the user wants the automatic windows to be automatically opened. As depicted in FIG. 8, the fresh air controller 300 can determine whether the windows have been/are set to automatically open, as shown in step 850. If windows are not set to automatically open, as depicted in FIG. 8, the fresh air controller 300 can proceed to step 870 to turn on the WHF and adjusting the WHF speed based on the inside temperature as discussed herein (for example at various speeds based on the inside temperature value). For example, when the windows are not set to automatically open and the user has turned on the system 100 to semi-automatic mode, it may be assumed that the user has manually opened at least one window in the building structure.

If the automatic windows are set to open automatically in step 850, as depicted in FIG. 8, the fresh air controller 300 can send a command signal to cause the one or more automatic windows to open and verify at least one window is open as discussed herein, as shown in step 860. The fresh air controller 300 can perform step 860 as discussed herein for step 780, resulting in the fresh air controller 300 performing operating commands according to either step 870 of turning on the WHF and adjusting the speed or step 880 of not turning on the WHF if one or more automatic windows cannot be verified to be open. If the fresh air controller 300 determines that at least one automatic window is not open in step 860, in some embodiments, as depicted in FIG. 8, the fresh air controller 300 can cause a push notification or prompt, via the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201, notifying the user which automatic window is not automatically opening.

In some embodiments, the fresh air controller 300 can generate and store a stored outside temperature value corresponding to the outside temperature value received by the fresh air controller 300 during the current iteration of the logic flow path after completing the WHF on logic flow path 802 and determining that the WHF should be turned on according to step 870. The stored outside temperature value can correspond to a previous temperature value for use in the control logic in any of the modes discussed herein. The previous temperature value can be associated with a time period ago between the current iteration of the logic flow path and the next time the fresh air controller 300 generates and stores a stored outside temperature value as discussed herein. In some embodiments, the time period ago can be a predetermined time period ago, a previous time period, or a predetermined previous time period corresponding to a time when the fresh air controller 300 retained the stored/previous outside temperature value.

In some embodiments, the fresh air controller 300 can delete or clear the stored outside temperature value if, during the WHF on logic flow path 803, the fresh air controller 300 determines the WHF should be turned off according to step 845.

In some embodiments, as depicted in FIGS. 9A and 9B, the fresh air cooling and ventilating system 100 can be set to operate in semi-automatic mode by a user with the system 100 including automatic windows. The control logic illustrated in FIGS. 9A and 9B can be implemented when the system 100 is initiated or controlled in the semi-automatic mode, in particular, from a smart phone application 220. The control logic illustrated in FIGS. 9A and 9B can be implemented when the system 100 is initiated or controlled in the semi-automatic mode from the user device 201, smart home connection 208, and/or webpage application 236. The control logic illustrated in FIGS. 9A and 9B can run iteratively at a range of different intervals including every minute, every five minutes, every 10 minutes, every 30 seconds, every 1 second, anytime in between, or anytime beyond 10 minutes. The interval at which the fresh air controller 300 can operate the logic can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.

In fresh air control logic diagram depicted in FIG. 9A, steps 901, 915, 925, 935, and 945 can correspond to steps 701, 715, 765, 775, and 785, respectively, described herein for FIG. 7. The fresh air controller 300 can perform steps 901, 915, 925, 935, and 945 in substantially the same manner as described above for steps 701, 715, 765, 775, and 785, respectively, with steps 915, 925, and 935 leading to step 945 or continuing in the logic sequence to, for example, to step 935, similar to steps 715, 765, and 775 leading to step 785 or continuing in the logic sequence to, for example, step 775 as discussed herein.

In the fresh air control logic diagram depicted in FIG. 9B, steps 910, 920, 930, 950, 960, and 962 can correspond to steps 710, 720, 760, 780, 790, and 792, respectively, described herein for FIG. 7. The fresh air controller 300 can perform steps 920, 930, 960, and 962 in substantially the same manner as described above for steps 710, 720, 760, 790, and 792, respectively, with steps 910 and 930 leading to step 962 or continuing in the logic sequence to, for example, to step 960, similar to steps 710 and 760 leading to step 792 or continuing in the logic sequence to, for example, step 790 as discussed herein. In FIGS. 9A and 9B, the WHF off flow path 902 is connected by the circle annotated with reference alpha “A” indicating that the WHF off flow path 902 continues between FIGS. 9A and 9B.

For the WHF off flow path 902, in some embodiments, as depicted in FIG. 9B, after determining whether the outside air quality index value is within operating parameters in step 920, the fresh air controller 300 can send a prompt or push notification, via the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201, to the user if the air quality index is not within operating parameters as discussed herein (for example, for step 725), as shown in step 922. The prompt or push notification can query the user at step 922 if the user would still like to turn on the WHF if the air quality is not within operating parameters. If the user indicates through one of the input devices discussed herein, including the smart phone application, that the user would still like to turn the WHF on, the fresh air controller 300 can proceed to the step 930 in the WHF off flow path 902. In some embodiments, if the user indicates they would not like to turn the WHF on, the fresh air controller 300 can proceed to not turn on the WHF according to step 962. In some embodiments, the fresh air controller 300 can generate such a prompt or push notification, asking the user if they want to continue, at any step in the control logic performed by the fresh air controller 300.

After performing step 930 as discussed herein, for example, in reference to step 760, in some embodiments, the fresh air control 300 can determine in step 940 whether the automatic windows are set to automatically open on the WHF off flow path 902. If the windows are not set to automatically open, the fresh air controller 300 can send a prompt or push notification, via the smart phone application 220, the web application 236, smart home connections 208, and/or the user device 201 as discussed herein, to the user as shown in step 942. The prompt or push notification can query the user whether the user would like to open the automatic windows manually or automatically, as shown in step 942.

If the user indicates or provides a user input that the user would like to open the windows manually, the fresh air controller 300 can send a prompt or push notification, via the smart phone application 220, the web application 236, smart home connections 208, and/or the user device 201, to the user asking whether one or more windows are open, as shown in step 954. If the user indicates there is a window open, in some embodiments, the fresh air controller 300 can send a command signal to cause the WHF to turn on and adjust the WHF speed based on the temperature inside the house as discussed herein (for example at various speeds based on the inside temperature value as discussed herein for step 790), as shown in step 960. If the user indicates that there is not a window open, the fresh air controller 300 may not send a command signal to turn on the WHF, as shown in step 962.

In some embodiments, if in response to the query of step 942, the user indicates they would like to open the windows automatically, the fresh air controller, as part of step 944, can determine or receive one or more signals indicating the number of automatic windows 228A-C connected to the fresh air controller 300. If the fresh air controller 300 determines or receives a signal indicating that one automatic window 228A-C is connected the system 100 or otherwise operational, the fresh air controller 300 can proceed to step 950 as discussed herein (for example, as discussed herein for performing step 780).

If the fresh air controller 300 receives a signal indicating two or more (more than) one automatic windows 228A-C are connected to the system 100 or otherwise operational, the fresh air controller 300, as part of step 946, can cause a prompt or user notification that iterates through the two or more automatic windows to ask the user for each particular automatic window if the user would like to have that particular automatic window open automatically. For example, the fresh air controller 300 can send a signal to cause a prompt for user to indicate if the user would like to open automatic window 228A, if the user would like to open automatic window 228B, and/or if the user would like to open automatic window 228C. If the user indicates that at least one of the automatic windows is to be opened automatically, the fresh air controller 300 sends a command signal to cause to open the particular (one or more) automatic window selected to be automatically opened and verifies that the particular (one or more) automatic window is open. After verification that the particular (one or more) window is open, the fresh air controller 300 can proceed to step 960 as discussed herein.

If the particular (one or more) window selected to be automatically opened is not verified to be open, the fresh air controller 300 can cause a prompt or user notification, via for example smart phone application, indicating there was a problem opening the particular (one or more) window. If none of the automatic windows are verified to be open, the fresh air controller 300 can proceed to step 952 and cause a prompt or user notification asking the user if the user would like to run the WHF without automatic windows according to step 952 as discussed herein, proceeding to step 954 or step 962 depending the user's input as discussed herein.

If the user indicates that none of the one or more automatic windows 228A-C are to be opened automatically in response to the iterative query of step 946, the fresh air controller 300 can cause a prompt or user notification, via for example the smart phone application, indicating that no windows were selected to be open and asking the user to manually open one or more windows in the building structure. The fresh air controller 300 can proceed to step 954 and cause a prompt or user notification asking the user if there is a window open in the building structure according to step 954 as discussed herein, proceeding to step 960 or step 962 depending the user's input as discussed herein.

Returning to step 940, if at step 940 the fresh air controller 300 determines that the automatic windows are set to operate automatically, the fresh air controller 300 can proceed to the step 950 of the WHF off logic flow path 902. At step 950, the fresh air controller 300 can send a command signal to cause the automatic windows to open and verify at least one automatic window is open as discussed herein. If the fresh air controller 300 determines that at least one automatic window is open in step 950, in some embodiments, as depicted in FIG. 9B, the fresh air controller can send a command signal to turn on the WHF and adjust the WHF speed according to step 960 as discussed herein.

If the fresh air controller 300 determines that at least one automatic window is not open in step 950, in some embodiments, as depicted in FIG. 9B, the fresh air controller 300 can cause a push notification or prompt notifying the user which automatic window is not automatically opening via the smart phone application 220, the web application 236, smart home connections 208, and/or the user device 201. If the fresh air controller 300 determines that at least one automatic window is not open in step 950, in some embodiments, as depicted in FIG. 9B, the fresh air controller 300 can cause a push notification or prompt asking the user if they would like to run the WHF without automatic windows, as shown in step 952, via the smart phone application 220, the web application 236, smart home connections 208, and/or the user device 201. In some embodiments, the fresh air controller 300 can receive information indicating the user's answer or input to the question of step 952 provided by the user through either the smart phone application 220, the web application 236, smart home connections 208, and/or the user device 201.

If the user's answer or input to the query of step 952 indicates that user would not like to run the WHF without automatic windows, the fresh air controller 300 can cause a push notification or prompt informing the user there is an issue with one or more automatic windows and to diagnose the settings or issues for the one or more automatic windows. If the user's answer the query of step 952 indicates the user would like to run the WHF without automatic windows, the fresh air controller 300 can cause a push notification or prompt asking the user if there is an open window in the building structure, as shown in step 954, via the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201. The window that is open according to step 954 can be an automatic window 228A-C as discussed herein or any other manual or traditional window in the building structure. The fresh air controller 300 can receive information indicating the user's answer or input to the question of query in step 954 provided by the user through either the smart phone application, web application, smart home connection, and/or user device. If the user indicates at least one window is open in the building structure, the fresh air controller 300 can send a command signal to cause the WHF to turn on and adjust the WHF's speed according to the inside temperature of the building structure as discussed herein, as shown in step 960. If the user indicates there is not at least one window open in the building structure, the fresh air controller 300 will not turn on the WHF, as shown in step 962, and can cause a push notification or prompt through either the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201 that the WHF will not turn on because there are no windows open.

In some embodiments, the fresh air controller 300 can generate and store a stored outside temperature value corresponding to the outside ambient temperature value received by the fresh air controller 300 during the current iteration of the logic flow path after completing the WHF off logic flow path 902 and determining that the WHF should be turned on according to step 960 discussed herein. The stored outside temperature value can correspond to a previous temperature value for use in the control logic in any of the modes discussed herein. The previous temperature value can be associated with a time period ago between the current iteration of the logic flow path and the next time the fresh air controller 300 generates and stores a stored outside temperature value as discussed herein. In some embodiments, the time period ago can be a predetermined time period ago, a previous time period, or a predetermined previous time period corresponding to a time when the fresh air controller 300 retained the stored/previous outside temperature value.

In some embodiments, the fresh air controller 300 can delete or clear the stored outside temperature value if, during the WHF on logic flow path 903, the fresh air controller 300 determines the WHF should be turned off according to step 945 discussed herein.

In some embodiments, as depicted in FIG. 10 the fresh air cooling and ventilating system 100 can be set to operate in a semi-automatic mode by a user with the system 100 not having or not being connected to automatic windows such as, for example, automatic windows 228A-C discussed herein, including when one or more of the automatic windows are not working or functioning properly. The control logic illustrated in FIG. 10 can be implemented when the system 100 is initiated or controlled in the semi-automatic mode from the smart phone application 220, web application 236, smart home connection 208, and/or user device 201. The control logic illustrated in FIG. 10 can run iteratively at a range of different intervals including every minute, every five minutes, every 10 minutes, every 30 seconds, every 1 second, anytime in between, or anytime beyond 10 minutes. The interval at which the fresh air controller 300 can operate the logic can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.

In fresh air control logic diagram depicted in FIG. 10, steps 1001, 1015, 1025, and 1035 can correspond to steps 701, 715, 765, and 775, respectively, described above in FIG. 7. The fresh air controller 300 can perform steps 1001, 1015, 1025, and 1035 in substantially the same manner as described above for steps 701, 715, 765, and 775, respectively, with steps 1015, 1025, and 1035 leading to step 1045 (without closing windows) or continuing in the logic sequence to, for example, step 1035, similar to steps 715, 765, and 775 leading to step 785 or continuing in the logic sequence to, for example, step 775 as discussed herein.

In the fresh air control logic diagram depicted in FIG. 10 steps 1010, 1020, 1030, and 1040 can correspond to steps 710, 720, 790, and 792, respectively described above in FIG. 7. The fresh air controller 300 can perform steps 1010, 1020, 1030, and 1040 in substantially the same manner as described above for steps 710, 720, 790, and 792, respectively, with steps 1010 and 1020 leading to step 1040 or continuing in the logic sequence to, for example, step 1030, similar to steps 710 and 720 leading to step 792 or continuing in the logic sequence to, for example, step 790 as discussed herein.

For the WHF off logic flow path 1002, in some embodiments, the fresh air controller 300 can send a command signal to cause the WHF to operate for a predetermined amount of time immediately after determining the attic temperature is within parameters for operation per step 1010. After the WHF runs for the predetermined amount of time, the fresh air controller 300 may proceed to step 1020 to continue the control logic as discussed herein. In some embodiments, the predetermined amount of time for operation of the WHF can be 30 minutes. In some embodiments, the predetermined amount of time for operation can be 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, or greater than 60 minutes.

As depicted in FIG. 10, some steps of the control logic for controlling the system 100 have a similar first step 1001 to the embodiment illustrated in FIG. 7. In some embodiments, as depicted in FIG. 10, the fresh air controller 300 may check certain operating parameters after determining the WHF is already running, as shown in step 1001, and following the WHF on flow path 1003. For example, as depicted in FIG. 10, in some embodiments the fresh air controller 300 may determine whether the attic temperature is within operating parameters, as shown in step 1015, and whether the outside temperature has increased by more than one degree Fahrenheit, as shown in step 1025. In some embodiments, as depicted in FIG. 10, after determining the attic temperature is within operating parameters, as shown in step 1015 and that the outside temperature has not increased by more than one degree Fahrenheit, the fresh air controller 300 can proceed to adjusting the WHF speed based on the temperature inside the living space, as shown in step 1035. In some embodiments, as depicted in FIG. 10, after determining the attic temperature is not within operating parameters, as shown in step 1015, or that the outside temperature has increased by more than one degree Fahrenheit, the fresh air controller 300 can send a send a command/operation signal to the whole house fan controller 200 to turn off the WHF as shown in step 1045. In some embodiments, after turning off the WHF, the fresh air controller 300 as shown in step 1027 can delete or clear the stored outside temperature value generated at the end of the WHF off flow path 1002, as described herein.

For the WHF off logic flow path 1002, in some embodiments, as depicted in FIG. 10, when determining whether the outside air quality index value is within operating parameters, as shown in step 1020, the fresh air controller 300 can send a push notification or prompt, via the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201, to the user if the air quality index is not within operating parameters as discussed herein (for example, for step 725), as shown in step 1022. The push notification or prompt can warn, alert, or inform the user that it is not preferable to operate the WHF. After sending the push notification or prompt notifying that it is not preferable to operate the WHF, the fresh air controller may proceed step 1024 to determine whether to turn the WHF on based on the inside temperature. By providing for the WHF to possibly operate as discussed herein after step 1022, the user may be provided with greater control over the system 100 and choice as to when to operate the fresh air cooling and ventilating system 100, despite for example, possibly an undesirable air quality index value as discussed herein.

For step 1024, if the fresh air controller determines the inside temperature is less than a predetermined value and is already cool enough, the fresh air controller 300 may proceed to step 1040 and will not turn on the WHF. If the fresh air controller 300 determines that the inside temperature is greater than the predetermined value, the fresh air controller 300 can proceed to step 1030 and adjust the WHF speed based on the inside temperature.

In some embodiments, the fresh air controller 300 can determine whether to turn the WHF on based on the first predetermined inside temperature as discussed herein. For example, the first predetermined inside temperature to which the fresh air controller 300 can compare the inside temperature to is the lowest predetermined temperature. In some embodiments, the fresh air controller 300 can proceed to step 1040 to not turn on the WHF when the inside temperature value is lower than the lowest predetermined inside temperature value. In some embodiments, the fresh air controller 300 can proceed to step 1030 to turn on the WHF and adjust the speed based on the inside temperature as discussed herein when the inside temperature value is greater than the lowest predetermined inside temperature value. In some embodiments, the first predetermined inside temperature can be the predetermined inside temperature value for WHF operation discussed herein with reference to step 760. In some embodiments, the predetermined inside temperature values to which the inside temperature is compared to can be set by the user utilizing the user device, smart phone application, smart home connection, and/or web application, or by the manufacturer or the system of the person installing the system or any combination of the above. This can help to not turn on, activate, or keep running the WHF if the building structure is already cooler than the user would like it to be.

In some embodiments, as depicted in FIG. 11 the fresh air cooling and ventilating system 100 can be set to operate in a semi-automatic mode by a user with the system 100 not having or not being connected to automatic windows such as, for example, automatic windows 228A-C as discussed herein, including when one or more of the automatic windows are not working or functioning properly. The control logic illustrated in FIG. 11 can be implemented when the system 100 is initiated or controlled in the semi-automatic mode, in particular, from the smart phone application 220. The control logic illustrated in FIG. 11 can be implemented when the system 100 is initiated or controlled in the semi-automatic mode from the user device 201, smart home connections 208, and/or webpage application 236. The control logic illustrated in FIG. 11 can run iteratively at a range of different intervals including every minute, every five minutes, every 10 minutes, every 30 seconds, every 1 second, anytime in between, or anytime beyond 10 minutes. The interval at which the fresh air controller 300 can operate the logic can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.

In fresh air control logic diagram depicted in FIG. 11, steps 1101, 1115, 1125 and 1135 can correspond to steps 701, 715, 765, and 775, respectively, described herein for FIG. 7. The fresh air controller 300 can perform steps 1101, 1115, 1125, and 1135 in substantially the same manner as described above for steps 701, 715, 765, and 775, respectively, with steps 1115, 1125, and 1145 leading to step 1145 (without closing windows) or continuing in the logic sequence to, for example, step 1135, similar to steps 715, 765, and 775 leading to step 785 as described herein or continuing in the logic sequence to, for example, step 775 as discussed herein.

In the fresh air control logic diagram depicted in FIG. 11, steps 1110, 1130, 1140, and 1150 can correspond to steps 710, 720, 790, and 792, respectively, described herein for FIG. 7. The fresh air controller 300 can perform steps 1110, 1130, 1140, and 1150 in substantially the same manner as described above for steps 710, 720, 790, and 792, respectively, with steps 1110 and 1130 leading to step 1150 or continuing in the logic sequence to, for example, step 1140, similar to steps 710 and 720 leading to step 792 or continuing in the logic sequence to, for example, step 790 as discussed herein.

In the fresh air control logic diagram depicted in FIG. 11, step 1134 can correspond to step 1024 described herein for FIG. 10. The fresh air controller 300 can perform step 1134 in substantially the same manner as described above for step 1024, with step 1134 leading to step 1140 or 1150 similar to step 1024 leading to step 1030 or 1040, respectively.

As depicted in FIG. 11, some steps of the control logic for controlling the system 100 have a similar first step 1101 to the embodiment illustrated in FIG. 7. In some embodiments, as depicted in FIG. 11, the fresh air controller 300 may check certain operating parameters after determining the WHF is already running, as shown in step 1101, and following the WHF on flow path 1103. For example, as depicted in FIG. 11, in some embodiments the fresh air controller 300 may determine whether the attic temperature is within operating parameters, as shown in step 1115, and whether the outside temperature has increased by more than one degree Fahrenheit, as shown in step 1125. In some embodiments, as depicted in FIG. 11, after determining the attic temperature is within operating parameters, as shown in step 1115 and that the outside temperature has not increased by more than one degree Fahrenheit, the fresh air controller 300 can proceed to adjusting the WHF speed based on the temperature inside the living space, as shown in step 1135. Alternatively, in some embodiments, as depicted in FIG. 11, after determining the attic temperature is not within operating parameters, as shown in step 1115, or that the outside temperature has increased by more than one degree Fahrenheit, the fresh air controller 300 can send a send a command/operation signal to the whole house fan controller 200 to turn off the WHF as shown in step 1145. In some embodiments, after turning off the WHF, the fresh air controller 300 can, as shown in step 1127 delete or clear the stored outside temperature value generated at the end of the WHF off flow path 1102, as described herein.

On the WHF off logic flow path 1102, in some embodiments, as depicted in FIG. 11, after determining the attic temperature is within parameters for operation, as shown in step 1110, the fresh air controller 300 can send a push notification or prompt, via the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201 asking the user whether there is a window open in the building structure, as shown in step 1120. If the user indicates there is not a window open, the fresh air controller 300 can proceed to step 1150 and not turn on the WHF. If the user indicates there is a window open in the building structure, the fresh air controller 300 can proceed to the step 1130 in the WHF off logic flow path 1102.

In some embodiments, as depicted in FIG. 11, when determining whether the outside air quality index value is within operating parameters on the WHF off flow path 1102, as shown in step 1130, the fresh air controller 300 can send a push notification or prompt, via the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201, to the user if the air quality index is not within operating parameters as discussed herein (for example, for step 725), as shown in step 1132. The push notification or prompt can warn or inform the user that it is not preferable to operate the WHF. The prompt or push notification can query the user at step 1132 if the user would still like to still turn on the WHF if the air quality is not within operating parameters. If the user indicates through one of the input devices discussed herein, including the smart phone application, that the user would still like to turn the WHF on, the fresh air controller 300 can proceed to the step 1134 in the WHF off flow path 1102. In some embodiments, if the user indicates that they would not like to turn the WHF on, the fresh air controller 300 can proceed to not turn on the WHF according to step 1150. In some embodiments, the fresh air controller 300 can generate such a prompt or push notification, asking the user if they want to continue, at any step in the control logic performed by the fresh air controller 300. By providing for the WHF to possibly operate as discussed herein after step 1132, the user may be provided with greater control over the system 100 and choice as to when to operate the fresh air cooling and ventilating system 100, despite for example, possibly an undesirable air quality index value as discussed herein.

In some embodiments, in the fresh air control diagram depicted in FIG. 11, step 1132 can correspond to step 922, described above in FIG. 9B. The fresh air controller 300 can perform step 1132 in substantially the same manner as described above for step 922 with step 1132 leading to step 1150 or continuing in the logic sequence to, for example, step 1140, similar to step 922 leading to step 962 or continuing in the logic to, for example, step 960.

In some embodiments, after turning on the system 100 and adjusting the WHF speed after completing an iteration of the WHF off logic path 1102, the fresh air controller 300 can store the stored outside temperature value corresponding to the outside temperature the fresh air controller received during the iteration of the WHF off logic path 1102.

In some embodiments, when semi-automatic mode is turned off manually either from the user device 201, switch 432, smart home connection 208, and/or smart phone application 220, the fresh air controller 300 can delete or clear the stored outside temperature value.

FIG. 12 depicts an embodiment of control logic for sending a push notification or prompt to the user to, for example, alert the user that it may an ideal or desired time to operate the WHF 102. The fresh air controller 300 can cause a push notification 216 or prompt to the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201. The control logic illustrated in FIG. 12 can run iteratively at a range of different intervals including every minute, every five minutes, every 10 minutes, every 30 seconds, every 1 second, anytime in between, or anytime beyond 10 minutes. The interval at which the fresh air controller 300 can operate the logic can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.

Steps 1201, 1210, 1220, 1230, 1240, 1250, and 1260 of FIG. 12 can correspond to steps 701, 715, 725, 735, 745, 755, and 760, respectively, as described herein for FIG. 7. The fresh air controller 300 can perform steps 1201, 1210, 1220, 1230, 1240, 1250, and 1260 in substantially the same manner as described above for steps 701, 715, 725, 735, 745, 755, and 760, respectively.

As depicted in FIG. 12 some embodiments of the push notification 216 logic flow of the fresh air cooling and ventilating system 100 have a similar first 1201 step to the embodiment of the control logic for controlling the system 100 depicted in FIG. 7. In some embodiments, as depicted in FIG. 12, the fresh air controller 300 may check certain operating parameters after determining the WHF 102 is not running. For example, after determining the WHF 102 is not running, the fresh air controller 300 can determine whether the attic temperature is within the parameters for operation as show in step 1210. The fresh air controller 300 can determine whether the air quality index value is within parameters for operation as shown in step 1220. If both the attic temperature and air quality index are within parameters for operation, the fresh air controller 300 can determine whether the outside humidity is within parameters for operation as shown is step 1230 and determine whether the current outside temp is within parameters for operation as shown in step 1240. As shown in FIG. 12, in some embodiments, if both the outside humidity and the outside temperature are within parameters for operation, the fresh air controller 300 can, for example, determine whether the inside temperature is greater than the outside temperature by comparing temperature values received for both the inside and outside temperatures as shown in step 1250. If the fresh air controller 300 determines the inside temperature is greater than the outside temperature as shown in step 1250, the fresh air controller can proceed to the step 1260 in the push notification logic flow and determine whether the inside temperature is greater than a predetermined temperature. If for each of steps 1210, 1220, 1230, and 1240 the fresh air controller 300 determines the parameters are within the parameters for operation, and the fresh air controller 300 determines the inside temperature is great than the outside temperature as shown in step 1250 and that the inside temperature is greater than a predetermined value as shown in step 1260, the fresh air controller 300 can send a push notification 216 or prompt alerting the user that it is a desirable, ideal, or optimum time to run the WHF or system as shown in step 1270. The push notification 216 or prompt can be sent to the smart phone application 220, the web application 236, smart home connection 208, and/or the user device 201.

If at any of steps 1210, 1220, 1230, and 1240, the fresh air controller 300 determines that the parameter is not within the operating parameters or if the fresh air controller 300 determines that the inside temperature is not higher than the outside temperature as shown in step 1250 or if the fresh air controller determines the inside temperature is below a predetermined temperature as shown in step 1260, the fresh air controller 300 can cancel the control logic, as shown in step 1202 and a push notification 216 or prompt will not be sent to possibly operate the WHF or system. The fresh air controller 300 will also cancel the control logic if the fresh air controller 300 determines the WHF 102 is already running or operating as shown in step 1201.

The control logic and function of FIG. 12 ensures that the user can be notified when it is an ideal or desired time to use the system. Thus, if the system 100 is not operating in automatic mode, there is a greater likelihood that the user will utilize the fresh air cooling and ventilating system 100 as opposed to an alternative system such as the air conditioning system to cool the building structure, possible achieving more of the cost and health benefits associated with operating the system 100.

In some embodiments, steps 1201, 1210, 1220, 1230, 1240, 1250 and 1260 can be reordered or removed. The fresh air controller 300 can operate the push notification or prompt control logic in a variety of different configurations performing only a select number of the steps shown in FIG. 12 before sending a push notification or prompt to the user. For example, in some embodiments, the fresh air controller 300 can perform step 1201, proceed to step 1250 skipping steps 1210, 1220, 1230, and 1240, and then perform step 1270, skipping step 1260.

FIG. 13 depicts an embodiment of a diagram of control logic for controlling the operation of a ventilation fan 118 in a system 100 where a ventilation fan 118 is part of the system as discussed herein. The control logic illustrated in FIG. 13 can run iteratively at a range of different intervals including every minute, every five minutes, every 10 minutes, every 30 seconds, every 1 second, anytime in between, or anytime beyond 10 minutes. The interval at which the fresh air controller 300 can operate the logic can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.

As described above, attic ventilation fans 118 can facilitation the expulsion of air 120 from the attic space. While the motorized fan or whole house fan 102 can expel air out of the attic space, the addition of ventilation fans 118 can increase the efficiency with which air is pushed out of the attic space thus allowing air from the living or interior space to be more easily pulled into the attic by the WHF 102. In some embodiments, there can be one ventilation fan or there can be multiple (one or more ventilation fans).

In some embodiments, the user can select whether or not the ventilation fan(s) 118 is utilized by the fresh air system 100 using the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

In some embodiments, as depicted in FIG. 13 at step 1301, the fresh air controller 300 can receive a signal from the whole house fan controller 200 or the WHF 102 indicating whether or not the WHF 102 is turned on.

In some embodiments, as depicted in FIG. 13, the fresh air controller 300 may take certain steps after determining the WHF 102 is turned off and following the WHF off logic flow path 1303. For example, the fresh air controller 300 can check whether power venting has been turned on by the user, as shown in step 1310. If power venting is turned off, the fresh air controller 300 can cancel the ventilation fan control logic. If the fresh air controller 300 determines power venting is turned on, the fresh air controller can proceed to the step 1330 in the WHF off logic flow path 1303. The fresh air controller 300 can connect via a wireless or wired connection (discussed herein such as Bluetooth) to the ventilation fan 118 and/or ventilation fan controller 224, as show in step 1330, and send a command signal to turn off the ventilation fan 118, as shown in step 1350. In some embodiments, the fresh air controller 300 can connect to the ventilation fan 118 and/or ventilation fan controller 224 through a wired connection, or through a Wi-Fi network, or by any other connection means known to those of skill in the art. In some embodiments, the steps of 1330 and 1340 may be omitted in the control logic if the system 100, including with the fresh air controller 300, maintains a connections with the ventilation fan while performing any of the control logic modes discussed herein.

As depicted in FIG. 13, in some embodiments, where the fresh air controller 300 receives a signal indicating the WHF 102 is currently operating or turned on, the fresh air controller 300 can take certain steps following the WHF on logic flow path 1302. The fresh air controller 300 can determine whether power venting is turned on, as show in step 1320. If the fresh air controller 300 determines power venting is turned off, the fresh air controller 300 can cancel the control logic, as show in step 1315 as described above. If the fresh air controller 300 determines that power venting is turned on, the fresh air controller 300 can connect via a wireless or wired connection (discussed herein such as Bluetooth) to the ventilation fan 118 and/or ventilation fan controller 224, as shown in step 1340, and send a command/operation signal to the ventilation fan 118 and/or ventilation fan controller 224 to turn on the ventilation fan, as shown in step 1360, and instructing the ventilation fan to operate at a predetermined speed. In some embodiments, the fresh air controller 300 can connect to the ventilation fan through a wired connection, or through a Wi-Fi network, or by any other connection means known to those of skill in the art.

The speed at which the ventilation fan operates can correspond to a speed selected by the user or one set by either the manufacturer or the installer of the fresh air cooling and ventilating system 100. Alternatively, the fresh air controller 300 can send a command/operation signal causing the ventilation fan controller 224 to operate the ventilation fan 118 at different speeds. For example, in some embodiments the ventilation fan controller 224 or ventilation fan 118 can operate at different speeds depending on the speed of the WHF 102. Alternatively, in some embodiments, the ventilation fan 118 can operate at different speeds depending on other variable or parameters discussed herein such as outside temperature and/or inside temperature.

FIG. 14 depicts an embodiment of a diagram of control logic for controlling the operation of the WHF 102 where a WHF 102 is part of the system 100 and where the system 100 is set to operate in either automatic mode or semi-automatic mode. The fresh air controller 300 can run the control logic of FIG. 14 iteratively at a range of different intervals including every minute, every five minutes, every 10 minutes, every 30 seconds, every 1 second, anytime in between, or anytime beyond 10 minutes. The interval at which the fresh air controller 300 can operate the logic can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.

In some embodiments, as depicted in FIG. 14 at step 1404 the fresh air controller 300 can send a signal or command to the whole house fan controller 200 to turn on the WHF in response to the user manually turning on the WHF using the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236, as depicted in step 1401. When the system 100 is set to run in semi-automatic or automatic mode after determining parameters are within operating conditions as depicted in step 1402, the fresh air controller 300 can turn on the WHF. In determining whether or not the parameters are within operating conditions, as depicted in step 1402, the fresh air controller 300 can receive values corresponding conditions inside and outside the building structure and compare them to operating parameters as discussed herein. For example, the fresh air controller 300 can determine whether the attic temperature, Air Quality Index, outside humidity, current outside temperature, and inside temperature are all within operating parameters in the same manner as steps 710, 720, 730, 740, and 760, respectively of FIG. 7 discussed herein. As part of step 1402, the fresh air controller 300 can also determine whether the inside temperature is greater than the outside temperature in the same manner as step 750 of FIG. 7 discussed herein.

As part of proceeding to step 1404, the fresh air controller can optionally perform step 1408 to open and/or verify one or more windows are open, for example, prior to proceeding to step 1404. The dashed lines linking steps 1408 to the rest of the control logic diagram depicted in FIG. 14 indicate that step 1408 is additional logic or feature that does not need to be performed by the fresh air controller 300. Either upon manufacture/initial programming by the installer or by input from the user, the system 100 can be configured to utilize step 1408 of the control logic or configured not to do so. In some embodiments, the user can control whether step 1408 is performed by utilizing the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236. Step 1408 can correspond to step 780 and can be performed in the same manner as step 780 of FIG. 7.

After sending a signal or command to turn on the WHF 102, the fresh air controller can proceed to step 1416 and adjust the WHF speed based on the temperature inside the building structure and/or the temperature outside the building structure. The adjustment of the WHF speed as depicted is step 1416 can correspond to step 775 of FIG. 7 and step 1416 can be performed in substantially the same manner as step 775.

In some embodiments, the adjustment of the WHF speed depicted in step 1416 can be based on the temperature outside the building structure. Where the fresh air controller 300 adjusts the WHF speed based on the temperature outside the building structure, the fresh air controller 300 can compare the inside temperature value to a first, second, and third predetermined outside temperature values. For example, if the outside temperature value is between the first and second predetermined outside temperature values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a first speed. If the outside temperature value is between the second and third predetermined outside temperature values, the fresh air controller 300 can send a command signal to operate WHF 102 at a second speed. If the outside temperature value is greater than the third predetermined outside temperature value, the fresh air controller 300 can send a command signal to operate the WHF 102 at a third speed.

In some embodiments, the first, second, and third WHF speeds correspond to a low, a medium, and a high speed, respectively. In some embodiments, the WHF is not limited to three speeds, but instead can have 1 speed, 2 speeds, 4 speeds, 6 speeds, or any number of speeds. In some embodiments, the number of speeds corresponds to the number of predetermined values to which the fresh air controller 300 can compare the outside temperature of the building structure such that, for example, the number of speeds is equal to the number of predetermined temperature values.

In some embodiments, the first predetermined outside temperature to which the fresh air controller 300 can compare the outside temperature to is the lowest predetermined temperature. In some embodiments, the fresh air controller 300 can send a command signal to turn off the WHF and close the automatic windows when the outside temperature value is lower than the lowest predetermined outside temperature value. In some embodiments, the predetermined outside temperature values to which the outside temperature is compared to can be set by the user utilizing the user device, smart phone application, smart home connection, and/or web application, or by the manufacturer or the system of the person installing the system or any combination of the above. This can help to not turn on, activate, or keep running the WHF if the building structure is already cooler than the user would like it to be.

As part of proceeding to step 1416, the fresh air controller can optionally perform step 1412, for example, prior to proceeding to step 1416. The dashed lines linking step 1412 to the rest of the control logic diagram depicted in FIG. 14 indicate that step 1412 is additional logic or feature that does not need to be performed by the fresh air controller 300. Either upon manufacture/initial programming by the installer or by input from the user, the system 100 can be configured to utilize step 1412 of the control logic or configured not to do so. In some embodiments, the user can control whether step 1412 is performed by utilizing the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236. Step 1412 can correspond to step 770 in FIG. 7 and can be performed in the same manner as step 770.

After adjusting the WHF speed as depicted in step 1416, the fresh air controller 300 can determine whether to turn off the WHF 102 based on the inside temperature of the building structure and/or the outside temperature of the building structure as depicted in step 1420. In order to determine whether to turn off the WHF 102 the fresh air controller can receive a value corresponding to the present air temperature outside the building structure. The fresh air controller can also store a value corresponding to the air temperature outside of the building structure at a previous time. For example, the previous time could be the time at which a previous iteration of the control logic was run or the outside temperature at the time the WHF 102 was turned on.

The fresh air controller 300 can compare the current outside temperature value to the previous outside temperature value and send a command or signal to cause the WHF 102 to turn off where the current outside temperature value is greater than the previous outside temperature value by a predetermine value. The predetermined value can be preset by the manufacturer or set by the installer or set the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236. In some embodiments, in step 1420, the fresh air controller 300 can perform the following comparisons in addition or in place of the above described comparison. In some embodiments, the fresh air controller 300 can perform any combination of the comparisons described above and below in any order as part of step 1420.

The fresh air controller 300 can compare the current inside temperature value to the previous inside temperature value and send a command or signal to cause the WHF 102 to turn off where the current inside temperature value is greater than the previous inside temperature value by a predetermine value. The predetermined value can be preset by the manufacturer or set by the installer or set the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236. In some embodiments, in step 1420, the fresh air controller 300 can perform the following comparisons in addition or in place of the above described comparison. In some embodiments, the fresh air controller 300 can perform any combination of the comparisons described above and below in any order as part of step 1420.

In some embodiments, in step 1420, the fresh air controller 300 can compare the current outside temperature to a predetermined maximum outside temperature value. Where the outside temperature value is greater than the predetermined maximum outside temperature value, the fresh air controller 300 can send a signal or command to turn off the WHF 102. The predetermined maximum outside temperature value can be preset by the manufacturer or set by the installer or set the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

In some embodiments, in step 1420, the fresh air controller 300 can compare the current outside temperature value to a predetermined minimum outside temperature value. The predetermined minimum outside temperature value can correspond to the first predetermined temperature as discussed herein for outside temperatures. Where the outside temperature is less than the predetermined minimum outside temperature value, the fresh air controller 300 can send a signal or command to turn off the WHF 102. The predetermined minimum temperature value can be preset by the manufacturer or set by the installer or set the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

In some embodiments, in step 1420, the fresh air controller 300 can compare the current inside temperature value to a predetermined maximum inside temperature value. Where the inside temperature is greater than the predetermined maximum inside temperature value, the fresh air controller 300 can send a signal or command to turn off the WHF 102. The predetermined maximum inside temperature value can be preset by the manufacturer or set by the installer or set the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

In some embodiments, in step 1420, the fresh air controller 300 can compare the current inside temperature value to a predetermined minimum inside temperature value. The predetermined minimum inside temperature value can correspond to the first predetermined temperature as discussed herein for inside temperatures. Where the inside temperature is less than the predetermined minimum inside temperature value, the fresh air controller 300 can send a signal or command to turn off the WHF 102. The predetermined minimum inside temperature value can be preset by the manufacturer or set by the installer or set the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

In some embodiments, step 1420 can correspond to steps 745, 755, and 765 of FIG. 7. The fresh air controller 300 can perform step 1420 in substantially the same manner as described above for steps 745, 755, and 765 with steps 745 and 755 leading to step 765. In some embodiments step 1420 corresponds to only one of steps 745, 755, or 765. In some embodiments, step 1420 can correspond to any combination of steps 745, 755, and 765.

Where the fresh air controller 300 determines the WHF 102 should not be turned off at step 1420, the fresh air controller can iteratively repeat steps 1416 and 1420 until the fresh air controller 300 determines the WHF 102 should be turned off, as depicted in step 1414, or the user manually turns off the WHF as depicted in step 1422. The user can manually turn off the WHF utilizing the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

Where the fresh air controller 300 determines the WHF 102 should be turned off (and in some embodiments, where the user manually turns off the WHF), the fresh air controller 300 can send a signal or command turning off the WHF 102. After or at the same time as sending a signal or command turning off the WHF 102 as depicted in step 1428, the fresh air controller can optionally perform steps 1424 and/or 1432 (as depicted by dashed lines in FIG. 14). Step 1424 can correspond to step 785 and can be performed in the same manner as step 785 of FIG. 7. As depicted in step 1432 the fresh air controller 300 can send a signal or command to turn on a thermostat connected to the system 100 thereby allowing climate of the building structure to be conditioned by an air conditioning system instead of the fresh air system 100 when conditions are not optimal or desired for the WHF operation.

FIG. 15 depicts an embodiment of a diagram of control logic for controlling the operation of the WHF 102 where a WHF 102 is part of the system 100 and where the system 100 is set to operate in a manual mode.

In some embodiments, as depicted in FIG. 15 step 1504, the fresh air controller can be configured to send a signal or command to open the automatic windows 228A-C after receiving a signal that the user has manually turned on the fresh air system 100, as depicted in step 1501, through either the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236. The user can also utilize the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236 to set a timer such that the fresh air controller turns on the system after a set amount of time. Step 1504 corresponds to Step 780 of FIG. 7 and can be performed in the same manner as step 780 of FIG. 7.

After sending a signal or command to open the automatic windows as depicted in step 1504, the fresh air controller 300 can send a signal or command to cause to turn on the WHF 102 as depicted in step 1508. The system will then wait for further input from either a timer set by the user or from manual input by the user.

In some embodiments, the user can utilize the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236 to set a timer such that the fresh air controller 300 turns off the system after a set amount of time as depicted in step 1510. In some embodiments, as depicted in FIG. 15 step 1516, after receiving a signal that the timer set by the user has run out, the fresh air controller 300 can send a signal or command to turn off the WHF 102. As depicted in step 1512, the fresh air controller 300 can send a signal or command to turn off the WHF 102, when the user set the system 100 to off mode using the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

After sending a signal or command to turn off the WHF 102, the fresh air controller can send a signal or command to close the one or more automatic window connected to the system 100 as depicted in step 1520. Step 1520 can correspond to step 785 of FIG. 7 and can be performed in the same manner as step 785.

In some embodiments, the fresh air controller 300 can adjust the WHF speed based operation or operational time of the WHF 102. The operation time can correspond to how long the WHF 102 has been working whether turned on by a user or automatically activated in any of the modes discussed herein. The fresh air controller 300 can track an operation time of the WHF 102 operating or receive time data associated with the operation time of the WHF 102 operating. For example, the fresh air controller 300 can have a clock or timer module that keeps track of how long the WHF 102 has been operating. The fresh air controller 300 can receive time data associated with time via cloud services 204 and determine operation time based on the time data.

With the fresh air controller 300 adjusting the WHF speed based on the operation time, the fresh air controller 300 can compare the operation time or a value corresponding to the operation time of the WHF 102 to a first, second, and third predetermined time values. For example, if the operation time is less than the first predetermined time, the fresh air controller 300 can send a command signal to operate the WHF 102 at a first speed. If the operation time value is between the first and second predetermined time values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a second speed. If the operation time value is between the second and third predetermined operation time values, the fresh air controller 300 can send a command signal to operate WHF 102 at a third speed. If the operation time value is greater than the third predetermined operation value, the fresh air controller 300 can send a command signal to cease or suspend operation of the WHF 102.

In some embodiments, the first, second, and third WHF speeds correspond to a high, a medium, and a low speed, respectively, and in particular as discussed above for operation of the WHF 102 based on operation time. In some embodiments, the WHF 102 is not limited to three speeds, but instead can have 1 speed, 2 speeds, 4 speeds, 6 speeds, or any number of speeds. In some embodiments, the number of speeds corresponds to the number of predetermined values to which the fresh air controller 300 can compare the operation time such that, for example, the number of speeds is equal to the number of predetermined operation time values.

In some embodiments, the first predetermined time value can be between 1 minute to 8 hours, 2 minutes to 6 hours, 3 minutes to 4 hours, 5 minutes to 2 hours, including any time between 1 minute to 8 hours.

The control logic illustrated in FIG. 16 can run iteratively at a range of different intervals including every minute, every five minutes, every 10 minutes, every 30 seconds, every 1 second, anytime in between, or anytime beyond 10 minutes. The interval at which the fresh air controller 300 can operate the logic can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.

In some embodiments, as depicted in step 1604 of FIG. 16, the fresh air controller 300 can send a command or signal to open the automatic windows 228A-C after determining whether to turn on the WHF 102 based on the temperature inside the building structure and/or the temperature outside the building structure as depicted in step 1602. In order to determine whether to operate the WHF, as depicted in step 1602, the fresh air controller 300 can receive temperature values corresponding to the temperature inside the building structure and/or outside the building structure. The fresh air controller 300 can send a signal or command to turn on the WHF if the inside temperature is great than the outside temperature. In some embodiments, as part of step 1602, the fresh air controller 300 can determine whether the inside temperature is within parameters for operation in a same manner as described in step 760 of FIG. 7 herein. In some embodiments, as part of step 1602, the fresh air controller 300 can determine whether the outside temperature is within parameters for operation in a same manner as described in step 740 of FIG. 7 herein. Step 1616 can correspond to Step 780 of FIG. 7 and can be performed in the same manner as step 780 of FIG. 7.

In some embodiments, in step 1602, the fresh air controller 300 can compare the current outside temperature to a predetermined maximum outside temperature value. Where the outside temperature value is less than the predetermined maximum outside temperature value, the fresh air controller 300 can send a signal or command to turn on the WHF 102. The predetermined maximum outside temperature value can be preset by the manufacturer or set by the installer or set the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

In some embodiments, in step 1602, the fresh air controller 300 can compare the current outside temperature value to a predetermined minimum outside temperature value. The predetermined minimum outside temperature value can correspond to the first predetermined temperature as discussed herein for outside temperatures. Where the outside temperature is greater than the predetermined minimum outside temperature value, the fresh air controller 300 can send a signal or command to turn on the WHF 102. The predetermined minimum temperature value can be preset by the manufacturer or set by the installer or set the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

In some embodiments, in step 1602, the fresh air controller 300 can compare the current inside temperature value to a predetermined maximum inside temperature value. Where the inside temperature is less than the predetermined maximum inside temperature value, the fresh air controller 300 can send a signal or command to turn on the WHF 102. The predetermined maximum inside temperature value can be preset by the manufacturer or set by the installer or set the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

In some embodiments, in step 1602, the fresh air controller 300 can compare the current inside temperature value to a predetermined minimum inside temperature value. The predetermined minimum inside temperature value can correspond to the first predetermined temperature as discussed herein for inside temperatures. Where the inside temperature is greater than the predetermined minimum inside temperature value, the fresh air controller 300 can send a signal or command to turn on the WHF 102. The predetermined minimum inside temperature value can be preset by the manufacturer or set by the installer or set the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

In some embodiments, as depicted in step 1616 of FIG. 16, the fresh air controller 300 can send a command or signal to turn on the WHF 102 after sending a signal or command to open the automatic windows 228A-C as depicted in step 1604.

In some embodiments, the fresh air controller 300 can perform step 1608, step 1612, or both step 1608 and step 1612 in addition to step 1616. The dashed lines linking steps 1608 and 1612 to the rest of the control logic diagram depicted in FIG. 16 indicate that steps 1608 and 1612 are additional logic or feature that does not need to be performed by the fresh air controller 300. Either upon manufacture/initial programming by the installer or by input from the user, the system 100 can be configured to utilize steps 1608 or 1612 of the control logic or configured not to do so. In some embodiments, the user can control whether steps 1608 and 1612 are performed by utilizing the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236. Step 1608 can correspond to step 1416 and can be performed in the same manner as step 1416 of FIG. 14 described herein. Similarly, step 1612 corresponds to step 770 in FIG. 7 and can be performed in the same manner as step 770 described herein.

After opening the one or more automatic windows 228A-C connected to the system in step 1616 and, in some embodiments, performing steps 1608 and 1612, the fresh air controller can proceed to determine whether to turn off the WHF based the temperature inside the building structure and/or outside the building structure as depicted in step 1620. Step 1620 can correspond to step 1420 of FIG. 14. The fresh air controller 300 can perform step 1620 in substantially the same manner as described above for step 1420.

Where the fresh air controller determines the WHF 102 should not be turned off at step 1620, the fresh air controller can iteratively repeat step 1620 until the fresh air controller 300 determines the WHF 102 should be turned off. Where the control logic of FIG. 16 includes the optional step 1608 and where the fresh air controller determines the WHF 102 should not be turned off at step 1620, the fresh air controller can iteratively repeat steps 1608 and 1620 until the fresh air controller 300 determines the WHF 102 should be turned off.

In some embodiments, the fresh air controller 300 can perform step 1626 in addition to step 1620. The dashed lines linking steps 1626 to the rest of the control logic diagram depicted in FIG. 16 indicate that step 1626 is additional logic or feature that does not need to be performed by the fresh air controller 300. Either upon manufacture/initial programming or by input from the user, the system 100 can be configured to utilize step 1626 of the control logic or configured not to do so. In some embodiments, the user can control whether step 1626 is performed by utilizing the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236. Step 1626 can correspond to step 725 and can be performed in the same manner as step 725 of FIG. 7 described herein.

If the fresh air controller 300 determines the WHF 102 should be turned off based on the temperature inside and/or outside the building structure in step 1620 and/or based on the air quality index in step 1626, the fresh air controller 300 can send a signal or command turning off the WHF 102 as depicted in step 1624. After sending a signal or command to turn off the WHF 102, the fresh air controller 300 can send a signal or command to close the one or more automatic windows. In addition to performing step 1628, the fresh air controller 300, after sending a signal or command to turn of the WHF 102 in step 1624, can send signal or command to turn on a thermostat connected to the system 100 as depicted in step 1632 thereby allowing climate of the building structure to be conditioned by an air conditioning system instead of the fresh air system 100 when conditions are not optimal for the WHF operation. The dashed lines linking step 1632 to the rest of the control logic diagram depicted in FIG. 16 indicate that step 1632 is additional logic or feature that does not need to be performed by the fresh air controller 300. Either upon manufacture/initial programming by the installer or by input from the user, the system 100 can be configured to utilize step 1632 of the control logic or configured not to do so. In some embodiments, the user can control whether or not step 1632 is performed by utilizing the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

FIG. 17 depicts an embodiment of a diagram of control logic for controlling the operation of the WHF 102 where a WHF 102 is part of the system 100 and where the system 100 monitors the air quality index (AQI) values as discussed herein to reduce undesired air pollutants inside the building structure by bringing in fresh air. The fresh air controller 300 can run the control logic of FIG. 17 iteratively at a range of different intervals including every minute, every five minutes, every 10 minutes, every 30 seconds, every 1 second, anytime in between, or anytime beyond 10 minutes. The interval at which the fresh air controller 300 can operate the logic can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.

The fresh air controller 300 can monitor the AQI values, information, and/or signals that are received from smart home connections 208, API connections 212, and/or sensors 230 as discussed herein. At step 1701, the fresh air controller 300 can determine whether AQI values inside the building structure are greater than the desired or predetermined threshold or range (e.g., beyond or outside of a desired condition or predetermined range). For example, one or more sensors 230 can monitor whether volatile organic compound (VOC) gases, carbon dioxide, carbon monoxide, smoke, particulates, and/or pollen in the building structure 106 (including attic space 104 and/or interior space 108) exceed or are greater than the desired levels or predetermined thresholds. Upon determining that the one or more AQI values exceed the predetermined levels, the fresh air controller 300 can send a push notification 216 at step 1702 to the user as discussed herein to alert the user that of the AQI value and associated information about the AQI level being greater than the predetermined levels, and/or the fresh air controller 300 can turn on the WHF as discussed herein to remove the undesired air pollutants inside the building structure (e.g., when AQI levels are high or above predetermined thresholds) by bringing in fresh air. The predetermined thresholds for AQI can be set by the manufacturer, by the installer, by the user, by the manufacturer, or by the installer and can be modified by the user.

In some embodiments, the fresh controller 300 can be programmed to not monitor or send command signals in response to carbon dioxide levels. High or undesirable carbon dioxide levels may indicate a fire inside the building structure. Turning on the WHF may further fuel and expand the fire. Accordingly, it may be undesirable to have the fresh air controller turn on WHF. In some embodiments, however, the fresh air controller 300 can monitor carbon dioxide levels inside the building structure. When carbon dioxide levels are above a predetermined range or threshold, the fresh air controller 300 can turn off the WHF for safety in case a fire is present inside the building structure and/or send a push notification 216 to the user alerting the user of the carbon dioxide levels exceeding a predetermined threshold.

In some embodiments, as part of step 1701, the fresh air controller 300 can compare inside AQI values to outside AQI values to determine whether to turn on the WHF. For example, even when inside AQI values our greater than the predetermined levels, if outside AQI values are greater by a larger amount or value of the predetermined levels, the fresh air controller 300 can determine to not turn on the WHF and/or not send a push notification 216 to the user regarding the AQI levels. The fresh air controller can determine and compare inside to outside AQI values using signal and value inputs from the climate condition system 217, air conditioning system 215, and/or one or more sensors 230 as discussed herein.

In some embodiments, as depicted in FIG. 17 at step 1704, the fresh air controller 300 can send a signal or command to the whole house fan controller 200 to turn on the WHF in response to the user manually turning on the WHF using the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236, as depicted in step 1704. When the system 100 is set to run in semi-automatic or automatic mode, after determining the AQI levels exceed the predetermined threshold as depicted in step 1701, the fresh air controller 300 can turn on the WHF as depicted in the step 1704. In determining whether the AQI levels exceed the predetermined threshold as depicted in step 1701, the fresh air controller 300 can receive values corresponding conditions inside and outside the building structure and compare them to AQI parameters such as thresholds as discussed herein.

As part of proceeding to step 1704, the fresh air controller can optionally perform step 1708 to open and/or verify one or more windows are open, for example, prior to proceeding to step 1704. The dashed lines linking steps 1708 to the rest of the control logic diagram depicted in FIG. 17 indicate that step 1708 is additional logic or feature that does not need to be performed by the fresh air controller 300. Either upon manufacture/initial programming by the installer or by input from the user, the system 100 can be configured to utilize step 1708 of the control logic or configured not to do so. In some embodiments, the user can control whether step 1708 is performed by utilizing the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236. Step 1708 can correspond to step 780 and can be performed in the same manner as step 780 of FIG. 7 using AQI values and thresholds as discussed herein to determine whether to open one or more windows and/or verify whether one or more windows are open.

After sending a signal or command to turn on the WHF 102, the fresh air controller can optionally perform step 1712, for example, prior to proceeding to step 1720. The dashed lines linking step 1712 to the rest of the control logic diagram depicted in FIG. 17 indicate that step 1712 is additional logic or feature that does not need to be performed by the fresh air controller 300. Either upon manufacture/initial programming by the installer or by input from the user, the system 100 can be configured to utilize step 1712 of the control logic or configured not to do so. In some embodiments, the user can control whether step 1712 is performed by utilizing the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236. Step 1712 can correspond to step 770 in FIG. 7 and can be performed in the same manner as step 770.

After sending a signal or command to turn on the WHF 102, the fresh air controller can optionally proceed to step 1716 (as depicted by dashed lines FIG. 17) and adjust the WHF speed based on the AQI values inside the building structure and/or the AQI values outside the building structure. The adjustment of the WHF speed as depicted is step 1716 can correspond to step 775 of FIG. 7 and step 1716 can be performed in substantially the same manner as step 775 using AQI values and comparisons thereof. The dashed lines linking step 1716 to the rest of the control logic diagram depicted in FIG. 17 indicate that step 1716 is additional logic or feature that does not need to be performed by the fresh air controller 300. Either upon manufacture/initial programming by the installer or by input from the user, the system 100 can be configured to utilize step 1716 of the control logic or configured not to do so. In some embodiments, the user can control whether step 1716 is performed by utilizing the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236. Step 1716 can correspond to step 775 in FIG. 7 and can be performed in the same manner as step 775.

In some embodiments, the adjustment of the WHF speed depicted in step 1716 can be based on the AQI values inside and/or outside the building structure. Where the fresh air controller 300 adjusts the WHF speed based on the AQI values inside the building structure, the fresh air controller 300 can compare the AQI values to a first, second, and third predetermined AQI values. For example, if the AQI values is between a first and second predetermined AQI values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a first speed. If the AQI value is between a second and third predetermined AQI values, the fresh air controller 300 can send a command signal to operate WHF 102 at a second speed. If the AQI value is greater than the third predetermined AQI values, the fresh air controller 300 can send a command signal to operate the WHF 102 at a third speed.

In some embodiments, the first, second, and third WHF speeds correspond to a low, a medium, and a high speed, respectively. In some embodiments, the WHF is not limited to three speeds, but instead can have 1 speed, 2 speeds, 4 speeds, 6 speeds, or any number of speeds. In some embodiments, the number of speeds corresponds to the number of predetermined values to which the fresh air controller 300 can compare the AQI values inside the building structure such that, for example, the number of speeds is equal to the number of predetermined AQI values.

In some embodiments, the fresh air controller 300 can proceed to step 1720 directly after step 1704. In some embodiments, the fresh air controller can optionally perform steps 1712 and/or 1716 as discussed herein. In step 1720, the fresh air controller can determine whether to turn off the WHF 102 based on the inside AQI values of the building structure and/or the outside AQI of the building structure. In order to determine whether to turn off the WHF 102 the fresh air controller can receive a value corresponding to the present air AQI. The fresh air controller can also store a value corresponding to the air AQI at a previous time. For example, the previous time could be the time at which a previous iteration of the control logic was run or the outside AQI at the time the WHF 102 was turned on.

The fresh air controller 300 can monitor the AQI values, information, and/or signals that are received from smart home connections 208, API connections 212, and/or sensors 230 as discussed herein. At step 1720, the fresh air controller 300 can determine whether inside and/or outside AQI values are less than the desired or predetermined threshold or range (e.g., beyond a desired condition or predetermined range) as discussed herein for step 1701, but upon determining that the inside and/or outside AQI values are within desired ranges, the fresh air controller 300 can send a push notification to the user and/or turn off the WHF.

For example, the fresh air controller 300 can determine whether AQI values inside the building structure are less than the desired or predetermined threshold or range (e.g., within a desired condition or predetermined range). One or more sensors 230 can monitor whether volatile organic compound (VOC) gases, carbon dioxide, carbon monoxide, smoke, particulates, and/or pollen in the building structure 106 (including attic space 104 and/or interior space 108) are within or less than the desired levels or predetermined thresholds. Upon determining that the AQI values within the predetermined levels, the fresh air controller 300 can send a push notification 216 at step 1721 to the user as discussed herein regarding the AQI value and associated information alerting the user that the AQI levels are within the predetermined levels and/or the fresh air controller 300 can turn off the WHF as discussed herein.

In some embodiments, as depicted in FIG. 17 at step 1720, the fresh air controller 300 can send a signal or command to the whole house fan controller 200 to turn off the WHF in response to the user manually turning off the WHF using the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236, as depicted in step 1728. When the system 100 is set to run in semi-automatic or automatic mode, after determining parameters are the AQI levels are within or less than the predetermined threshold as depicted in step 1720, the fresh air controller 300 can turn off the WHF as depicted in step 1728. In determining whether the AQI levels are within the predetermined threshold as depicted in step 1720, the fresh air controller 300 can receive values corresponding conditions inside and outside the building structure and compare them to AQI parameters or thresholds as discussed herein. The fresh air controller 300 can perform similar logic and control steps as discussed herein for outside AQI values or comparison of inside to outside AQI values as discussed herein for step 1701, but turning off the WHF when the AQI levels are less than or within predetermined levels or thresholds.

In the automatic or semi-automatic mode, where the fresh air controller 300 determines the WHF 102 should not be turned off at step 1720, the fresh air controller can iteratively repeat steps 1720 until the fresh air controller 300 determines the WHF 102 should be turned off, as depicted in step 1714, or the user manually turns off the WHF as depicted in step 1722. The user can manually turn off the WHF utilizing the use the switch 432, user device 201, smart phone application 220, smart home connection 208, and/or the web application 236.

Where the fresh air controller 300 determines the WHF 102 should be turned off (and in some embodiments, where the user manually turns off the WHF), the fresh air controller 300 can send a signal or command turning off the WHF 102. After or at the same time as sending a signal or command turning off the WHF 102 as depicted in step 1728, the fresh air controller can optionally perform steps 1724 and/or 1732 (as depicted by dashed lines FIG. 17). Step 1724 can correspond to step 785 and can be performed in the same manner as step 785 of FIG. 7. As depicted in step 1732 the fresh air controller 300 can send a signal or command to turn on a thermostat connected to the system 100 thereby allowing climate of the building structure to be conditioned by an air conditioning system instead of the fresh air system 100, for example, when conditions are not optimal or desired for the WHF operation as discussed herein.
