Customer Question

We have a TopTech T855 thermostat for our HEIL heating and cooling unit. The fan runs when we program the thermostat to cool but the HEIL unit won't turn on the fan for the air conditioning to run. How do I get the fan to run when I program the thermostat?

Well, it's a new unit and a new thermostat. It only has cool mode and the AC fans on the new unit won't run even if we turn the cooling mode on the thermostat.
