Has anyone changed out their 3 wire Dometic digital thermostat to a programmable one? I know the relays are all in the rear ac control. There is a 6 or 7 wire cable running from the current thermostat to the ac. Setting up the furnace part should be fairly straight forward by disconnecting the wires running to the furnace from the ac and using existing cable wires to control the furnace using the standard wire color code. How would the ac have to be wired? The thermostat would be AA battery powered so the existing 12v+ & - wires probably won't be used. Any ideas?
