The orange and white wires plug into the control box. This is the 120VAC power that comes from the control box and powers the heat strip (not a furnace) located in the Air-conditioner.
The red wire I refer to is the typical 12V wire at the LP furnace. Coleman thermostats are typically powered from this 12V power source.
You can use any 12V you can find but you have to run it to the thermostat. Coleman thermostats need 12V to the red wire. Then the thermostat sends 12V up the ceiling control box. The ceiling control box then sends 120VAC to the AC compressor, low and high fan and the heat strip depending on your thermostat settings.
Just curious, do you also have an LP (Propane) furnace, If yes, is there another thermostat to control it?
Aaaah!
No, I don't have a furnace, but can I use a 120vac to 12vdc converter in this case.
If I can, then the 12vdc will connect to the thermostat red wire (12vdc), but where the negative wire should be connected to?
Thanks
