Question:
I’m replacing the ACs on my RV and want to know if the Coleman-Mach WiFi Thermostat for RV Air Conditioners and Heat Pumps - Black CM46MR will work with the new ducted Mach systems like the Signature Mach 15 CM52RR, Roughneck Mach 15 CM65RR, Signature Mach 3 CM83RR, and Roughneck Mach 3 CM95RR.

Hey Brian!
Yes, the WiFi Thermostat # CM46MR will work with the new ducted Coleman-Mach units like # CM52RR, # CM65RR, # CM83RR, and # CM95RR. Since those are the ducted kits that already use a wall thermostat, that’s where this add-on thermostat makes the most sense. If you want, tell me what RV you have and how many AC units you’re planning to run.
And just to be sure, the ducted units are for RVs that have AC vents in the ceiling that carry air through the coach. If your RV does not have ceiling vents and the air only blows right from the inside ceiling assembly, you’d instead want a ductless system like the Signature Mach 3 # CM58RR, Roughneck Mach 3 # CM68RR, Signature Mach 15 # CM93RR, or Roughneck Mach 15 # CM88RR. Just keep in mind those ductless kits use control knobs on the air distribution box, so they are not the ones you’d typically pair with the WiFi thermostat.
