On Page 19 of the install manual, it says to program "O" if I have a gas furnace (system controls fan operation)....or program "1" if I have an electronic heating system (thermostat controls fan operation).
My confusion is that I have a fan "on/off" switch on my current thermostat, and their instructions seem to contradict as I can currently control the fan operation from the thermostat unit. Any idea which program button is correct?
