Heat pump and furnace come at same time
This just started to happen: If the thermostat is set on "Auto" or "Furnace" the furnace and the heat pump come on at the same time. I have to check to see if it happens on "Heat Pump" as well.
I've lived with it for a few weeks by turning the breaker for the Heat Pump off so just the furnace will come on.
Anyone else run into this? I'm not sure if it's a thermostat or the electronic controller in the heart pump that is causing the problem.
I'm on warranty, but if it's the thermostat, it would be cheaper to just replace it rather than tow a 5-6 hour round trip to the dealer.
