Abstract: An HVAC system includes an HVAC unit having a cooling mode and a heating mode for conditioning the air in an inside space, and a programmable thermostat located remotely from the HVAC unit. The HVAC unit may have an onboard controller configured to control when the HVAC unit is in the cooling mode or heating mode, and whether the HVAC unit is activated or not. In some cases, the onboard controller of the HVAC unit may use a common temperature setpoint when controlling in the cooling mode and the heating mode. The programmable thermostat may have a programmable schedule with a plurality of time periods, where each time period has a heating setpoint and a cooling setpoint separated by a dead band. The onboard controller of the HVAC unit may be configured to accept input signals from the remotely located thermostat.

Abstract: A controller equipped with a user interface having a separate schedule review mode, including methods of accessing and/or programming such devices, are disclosed. The controller may include a user interface that can be utilized to initiate a scheduling routine having a separate schedule review mode for displaying one or more schedule parameters of the controller without initiating the editing mode. An illustrative method of accessing a schedule on a controller coupled to a user interface may include the steps of initializing a scheduling routine within the controller, initiating a schedule review mode within the controller, displaying one or more schedule parameters for at least one period on the user interface, and exiting the scheduling routine. One or more of the schedule parameters can be modified, if desired, by initiating a separate editing mode within the controller.

Abstract: A wireless thermostat may be associated with a user account of an external web service that may facilitate remote access and/or control of the wireless thermostat. A remote device may be used to access a user's account hosted by the external web service. The wireless thermostat may be identified to the external web service and associated with the user's account by one or more unique identifiers previously delivered to the remote device from the wireless thermostat.

Abstract: A master HVAC schedule for an HVAC controller may be stored on an external server accessible over a computer network. The external server may maintain the master HVAC schedule, and may translate a portion of the master HVAC schedule into a basic HVAC schedule that is executable by an HVAC controller. The external server may deliver the basic HVAC schedule to an HVAC controller according to a predetermined schedule. In some cases, the external server may deliver an updated basic HVAC schedule to the HVAC controller in response to a user initiated change made to the master HVAC schedule or upon restoration of a lost network connection between the HVAC controller and the external server.

Abstract: A building automation system may adjust operation of a building system based upon information regarding the relative location of one or more users of the building automation system. In some embodiments, a mobile device having location services for determining a location of the mobile device may provide this information. A mobile device may include a user interface, a memory for storing two or more predetermined geo-fences each defining a different sized region about a home of a user of the mobile device and a controller operatively coupled to user interface and the memory, the controller configured to accept a selection of one of the two or more predetermined geo-fences via the user interface. The controller may report when the location of the mobile device crosses the selected one of the two or more predetermined geo-fences to a remote device. Other geofencing approaches are also described.

Abstract: An HVAC controller may be programmed using a mobile device having a touch screen display, a wireless port and a controller that is in operative communication with the touch screen display and the wireless port. The controller may establish communication with and download an application program code from the remote download server. The controller may establish a direct wireless connection between the wireless port of the mobile device and the wireless interface of the HVAC controller and execute the application program code, which provides one or more configuration screens on the touch screen display of the mobile device to enable the user to configure the HVAC controller via one or more configuration parameters, and then upload the one or more configuration parameters to the HVAC controller via the direct wireless connection between the wireless port of the mobile device and the wireless interface of the HVAC controller.

Abstract: An equipment interface module that can operate one or more pieces of HVAC equipment in accordance with instructions received from a properly operating thermostat, yet can also operate the HVAC equipment when communications between the thermostat and the HVAC controller are lost due to, for example, low battery power at the thermostat, malfunctioning thermostat sensor(s), malfunctioning communication and/or thermostat circuitry, electrical interference, and the like. In some instances, the equipment interface module may regulate the HVAC equipment in accordance with a signal from a remote sensor when communication with the thermostat is lost.
