OK, Thanks to all. I just happened to check back before going to bed. The unit has 6 wires coming from the wall all hooked into a board. 5 of the wires are tiny and multi colored and the 6th wire is larger and blue. It is a two stage heater and A/C. Yes it turns to a lower fan setting when close to temp. I will take pics tomorrow for all to see. Can someone remind me on how to post pics? This unit was recommended on amazon, Take it or leave it... I will call Coleman on Monday to see if this will do it. I hate dometic.
