Thermostat wiring question
I've a 2013 215wsk, I replaced the dometic rooftop 13.5 AC with a Houghton 15k heatpump. The Houghtons thermostat is self contained and is accessed via hand held remote. The T.T. stock thermostat now seems to have no power so I'm unable to use the T.T. propane furnace. Although when I'm plugged in I'll likely to use the heatpump I'd like to avoid running the gen set when dry camping and heat with propane.
In the AC roof cavity there is a wire marked 12v thermostat. Then there is a 4 contact white female plug that use to plug into the old Dometic. That plug has two red, one orange and one black. One red provides 12v+ the black is ground, the other red has no voltage nor dose the orange. When I jump the two reds together the thermostat wakes up provides the temp it's set to and a E1 error code I guess. When the reds are still jumpered the orange is energized with 4.3v+.
With the wires jumpered I still have no response from the furnace when the thermostat is set to heat and temp bumped up above ambient. Fan also will not energize when thermostat is set to heat or fan.
How do I wire this so furnace is controlled by thermostat?
