Question:
Hello, I have a 2025 FR East to West Ahara 395FB and want to replace my Thermostats with a single wifi Thermostat. Is the CM46MR able to hook up to multiple units? We have two units in the living and kitchen area with both controls side by side on the center pillar. Can this thermostat replace my current analog controles or am I out of luck and have to replace each one?

Hey Patrick, thanks for reaching out. Based on your description, it sounds like your Ahara has two separate analog thermostats, with each one controlling its own A/C unit. In that case, the Coleman-Mach WiFi Thermostat # CM46MR is not designed to replace two independent thermostats with a single unit. Each # CM46MR controls a single compatible Coleman-Mach HVAC control circuit, so if your two A/C units operate independently, you would need one thermostat for each system.
That said, if you want a smart thermostat that can control both AC units, we do have the following:
- Waltech Vision 2.0 RV Thermostat and Wireless Control Hub - Bluetooth # WA74FR
This is capable of working with multi-zone RV HVAC systems, including setups with two A/C units, provided your existing AC was made prior to 2025 and uses R410a refrigerant. It can also be used to monitor your holding tanks and propane tanks. It is Wifi and Bluetooth compatible.
What kind of AC units do you have?

My A/Cs are 2025 Coleman-Mach 37200 series air conditioners with P/N 1980-207. Will the Waltech Vision 2.0 RV Thermostat and Wireless Control Hub - Bluetooth # WA74FR work with my units? One of my 37200 units controls my propane heater for the RV so the thermostat needs to control that function. I also have a Coleman-Mach 3700 series Heat pump with P/N 1980-211 in my bedroom. I may get the single thermostat for it if I need it down the road.
