So I went over to the trailer today and took a look at the back of the mechanical Atwood thermostat. As seen in the pic, there are just the two wires.
I went to wal-mart and bought the honeywell heat/cool RTH111B thermostat (battery operated). Again, I only have a need for the thermostat to control the furnace.
So, does anyone want to chime in and tell me/give me an idea on which wire might go where? I will have to go back and take a closer look, but I couldn't tell if the old thermostat showed any writing or a label for the current wires. My initial guess is that the one with red/white comes from the 12 V DC battery. But I just don't know.....
Would like to go to the trailer tomorrow and try to wire it so any help would be appreciated!
