OPERATING YOUR THERMOSTAT
Choose the Fan Setting (Auto or On or Prog)
Fan Auto is the most commonly selected setting and runs the fan only when the heating or cooling system is on.
Fan On selection runs the fan continuously for increased air circulation or to allow additional air cleaning.
Fan Prog will run the fan when the heating or cooling system is on. In addition, when the thermostat has not called for heat or cool for more than 60 minutes, it will begin to cycle the fan for 10 minutes on and 20 minutes off to improve indoor air quality. This is the Comfort Circulating Fan Feature.
