We have the Coleman 'Airxcel' thermostat in our Keystone Sprinter. It is the basic unit, one long rectangular button on the bottom for mode, and then two triangular buttons to go up or down on temperature. Long story short, it is cutting out randomly on us, which is really frustrating. Sometimes it will blank out completely, in which case tapping on or messing with the unit will usually get it to 'power' back on, and sometimes it just kicks off before reaching the set temperature, but the display still functions so you can just restart it. When we are all in the camper for a while it will sometimes run flawlessly all day, other times it will glitch out 2-3 times within a half hour. If we are gone all day, we always come back to a 100+ degree camper. I have very little confidence in the cheapness of this unit, so I would much rather replace it with a wired, programmable one. What options are there that will still utilize the stock wiring? It's got red blue green white and yellow wires going into it.
