Phaeton Three Heat Pumps & Furnace Control
Our 2015 Phaeton has three air conditioners with heat pump. I seem to recall if the middle heat pump thermostat setting was 5 degrees more than ambient temperature it would start the front furnace. I know the front thermostat will do that and the rear thermostat will start the rear furnace.
We had a thermostat failure on the front air conditioner requiring replacement. Since the original thermostat is no longer made, we upgraded to the Micro-Air WiFi thermostat. We liked it so much we upgraded the other two. However, the middle thermostat wonít start the furnace and I canít recall correctly if it ever did.
Does anyone with the same setup know if the middle thermostat will operate the furnace?
