Any help would be appreciated. I had an Atwood thermostat in a 2003 jayco designer camper.
The atwood thermostat has died.
I bought a Coleman mach thermostat For now i want to hook up the Mach thermostat for air conditioning
The old thermostat had 7 wires coming out of the wall.
3 wires came from the furnace as follows:
1 red supplying 12 v current{a smaller diameter wire}
1 white {common}
1 white larger wire
There is another bundle enclosed in a gray sheath. They are small diameter thermostat wires
1 red {power}
1 blue{compressor)
1 green (fan)
1 white (common)
The new thermostat has the following:
B(12volt-)Blue
R(12 volt+)Red
Y(Cooling)Yellow
W(heat)
GH(High fan) Green
GL(Low fan)Gray)
What wire do I hook together to be able to use the air conditioner?

Assuming your functional descriptions are correct (perhaps they are labeled?)
Connect both commons to B
Connect both reds to R
Connect the larger white wire to W
Connect compressor to Y
Connect fan to GH and GL

Can you post a number off the Atwood tstat? Can you also post the Model Number of your Furnace? When OEM's used the Atwood tstat, it was because the furnace was a 2 speed furnace. It required the Atwood Tstat to operate the furnace correctly. That is why you have extra wires on your existing wiring. Doug
