Replaced Coleman Mach Themostat with LUXPRO
Here is the wiring diagram I used to wire the LUXPRO stat I bought on Amazon for 29 bucks and change. This is a 5-2 day programmable unit.
I did not install a switch for low high fan, so the green wire was connected to G and the grey and blue Mach wires were taped back. When testing there is a 5 minute delay built in before you can test the other function, like cooling after testing heating. I just cut the Mach colored wires about 3-4" from where they are soldered onto the Mach circuit card and stripped the insulation to make the connections to the LUXPRO. Jumper in LUXPRO should be set to gas.
I have used a very similar LUX model before, so it is like old home week.
