Abstract: An HVAC controller, such as a thermostat, may be configured to allow a user to set and/or select schedule time period in which one or more indoor quality units (e.g. humidification, dehumidification, ventilation, etc.) will or will not operate, and/or will operated but using different settings. In some cases, the schedule time periods available for selection may correspond to the time periods of a programmable temperature schedule of the HVAC controller, but this is not required. In some instances, the HVAC controller may allow a user to select which indoor air quality units will or will not operate, and/or what settings the indoor air quality units will operate, during a user's vacation.

Abstract: An HVAC controller for controlling an HVAC system may be configured to enroll one or more wireless devices, and once one or more wireless devices are enrolled, to prompt the user to enter an identifier, a location, a device type and/or a function for one or more of the enrolled wireless devices. The HVAC controller may use the identifier, location and/or device type to identify each of the enrolled devices. This may facilitate a user in selecting various sensors to participate in sensor averaging, identifying where certain sensor data is originating, identifying devices having a low battery condition, as well as performing other tasks as desired.

Abstract: A Heating, Ventilation, and/or Air Conditioning (HVAC) controller, such as a thermostat, is configured to receive and accept one or more requests for a temporary boost in ventilation. The requests may be received from one or more remotely located ventilation boost control units located throughout the building, and/or through a user interface of the HVAC controller itself. In some cases, the HVAC controller may be configured to coordinate multiple requests for ventilation, and adjust the ventilation time as appropriate.

Abstract: Methods and systems for monitoring the condition of a new air filter installed in an HVAC system are disclosed. In one example, an input that indicates a new air filter has been installed may be accepted, and in response, the HVAC system may be automatically operated in an air filter verifying mode, in which the fan of the HVAC system is activated to drive air through the new air filter. While in the air filter verifying mode, a measure related to an amount of flow restriction presented by the new air filter may be received. A status of the new air filter may be determined based, at least in part, on the received measure related to the amount of flow restriction presented by the air filter of the HVAC system. Once the status of the new air filter is determined, an indication may be displayed on a display, which may communicate the determined status of the new air filter to a user.

Abstract: Methods and systems for indicating a status of an air filter of an HVAC system may include receiving a measure that is related to an amount of flow restriction presented by the air filter in an HVAC system, using the measure to determine whether the air filter does not need replacing, the air filter needs to be replaced soon, or the air filter should be replaced now, and displaying on a display of an HVAC controller an air filter status indicator, wherein the air filter status indicator includes a stop-light metaphor. In one example, the air filter status indicator may display a green color when the air filter does not need replacing, display a yellow color when the air filter needs to be replaced soon, and display a red color when the air filter should be replaced now. In some cases, the air filter status indicator may also include a qualitative term indicative of the current status of the air filter.

Abstract: A clean air filter may be used to set an air filter change threshold value for an air filter monitor installed in an HVAC system. The air filter change threshold value may be used to determine a status of an air filter (e.g., clean or dirty).

Abstract: A blocking panel may be used to set an air filter change threshold value for an air filter monitor installed in an HVAC system. The air filter change threshold value may then be used to determine a status of an air filter (e.g., clean or dirty).
