Help with wall thermostat

I have a Carrier AC unit which has a remote thermo. I want to change it to a wall mount. Has any body done this or try ed it? The camper is wired for the wall mount but don't know what wire goes where. There is only two wires going to furn. from the ac now and they are 12v in and 12v out. So there must be a relay in the ac unit that tells the furn to come on and go off. The problem with the thermo. in the ac is that when you run the fire place heat rises and you freeze in the bed room because the furn. want come on. So if you have changed this out please help.
