Replacing Coleman thermostat

[rrev]

I apologize if this has been answered before but I can't find the answer. I'm looking to replace the Coleman Mach analog thermostat with a digital unit. I'm looking at the Dometic 3313192.019 so we can have the a.c. fan running with the furnace. Does anybody know if this is compatible? Thanks.

Dometic uses a digital signal to a relay box specific to Dometic. Just 3 wires to the thermostat and 2 are for 12v power.

It might be possible to adapt the relay box. You would need the wire diagram for both and connect accordingly.

Possibly Coleman has a digital replacement that is compatible? I would look there first.

Here is my Dometic install for comparison: (I have a Dometic A/C)

I checked on the one recommended and noticed it had a background lighting on the face, For me that was a must after groping around in the dark setting one with no background lighting.

Anyone have tips for adding a wall thermostat to a Coleman Mach that just has the red/blue knob directly on the unit... is it possible, like if I open a panel somewhere, there's connections for a wall mount thermostat?

If you mean you have the ceiling mount with the 2 knobs---NO. There is no tstat wiring there and none would have been run by the OEM. To do a Wall tstat, you will have to buy a new ceiling kit and a ceiling control board and the wall tstat and then run the tstat wiring from the roof to the wall. Doug

Bummer... Thanks for the fast reply.

You cannot use the Dometic with the RVP Coleman system. You need to look at the Aftermarket one from Lowes. Doug

I replaced mine with a digital programmable tstat at Lowes for around $30. I can run furnace and AC fan on manual at the same time. Works great.

Just did the same thing recently and it works perfectly.

Here's the one I installed... http://www.lowes.com/pd_356344-74493-RTHL2310B1008_1z0vjkgZ1z10xtrZ2z8vm__?productId=3464340&pl=1

Same model I have.
