Questions buyers ask
Questions buyers ask
Which option do I pick?
Analog if you want a simple slider stat. WiFi to start and schedule the air conditioner from your phone. The heat pump option only if the unit on your roof is a Coleman-Mach heat pump.
Do I need to run wires?
Yes: thermostat wire from the ceiling assembly to the wall, and 12 V DC to the thermostat circuit. Most RVs have 12 V nearby at a light or the furnace stat. If that is a problem, the Bluetooth ceiling assembly needs no wall wiring.
Can I keep my furnace on the same thermostat?
Yes. Both stats have a heat setting that runs a single-stage 12 V furnace.
Can I add a heat strip later?
Yes, on the two heat-ready options: 38203-4551 for Mach 3, 15 and 10, 37203-4551 for the Mach 8.

About Coleman-Mach
About Coleman-Mach
Coleman-Mach rooftop air conditioners are built by Airxcel in Wichita, Kansas, and have been since 1967. They are the original equipment on more RVs than any other brand, which is why the ceiling assemblies, controls and repair parts are still available for units twenty years old. Every unit carries the Coleman-Mach 2-year limited warranty; Kate RV handles the claim with Airxcel for you.
