Abstract: An HVAC system within a building including a ventilator, a number of sensors, and a control device. The control device has a processor that is configured to receive a request to operate the ventilator. The control device is further configured to determine a status of a minimum runtime mode of the ventilator. The minimum runtime mode operates the ventilator for a minimum amount of each time in a predefined time period. The control device is further configured to determine an air quality value. The air quality value is based on one or more measurements provided to the control device by the plurality of sensors. The control device is further configured to operate the ventilator based on the air quality value being determined to be below an acceptable value.
