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.
