Does Replacement Digital Wall-Mounted Thermostat # AT15029 Control Furnace


You say this thermostat will not control a furnace then why is there a furnace button on the front?


Expert Reply:

The furnace button of the Thermostat # AT15029 can be used really only if you have a heat pump furnace model. That'll allow you to press once to select the furnace as your primary heating. Press it again to go back to the heat pump. Basically it's a way to select the heat pump as the warming source for the thermostat or a furnace bypass.
