Abstract:
An HVAC system within a building including an HVAC device having a blower fan, a number of sensors, and a control device. The control device has a processor that is configured to receive a request to operate the blower fan. The control device is further configured to determine an air quality value based on measurements provided by the sensors, and a runtime of the blower fan within a previous time frame. The control device is also configured to operate the blower fan based on the determined air quality value and the determined runtime of the blower fan within the previous time frame.
