I was replacing a analog thermostat. The swap was very easy. However I am electronics savey. But I do feel it is a great product.

Had it for over a month now. It works as described. We have a seasonal site for our camper so it’s always set up. It’s so nice to turn the AC on from my phone before we get there. Worth the money to not walk in to a 95* camper that needs cooled down.

The install was pretty simple once I had the right understanding of wiring for the current equipment. I have just a Coleman-Mach AC unit (no heat) on my RV. With the wires, Red, Blue, Gray, Yellow, White and green. The difficulty was matching the existing wire colors to the right port of the new thermostat. The manual helped with identifying what colors did what on the new unit, had to figure out (google) what the old unit was. Overall, easy setup, took about 30 minutes to do. The application works great and easy to use. The Alexa integration is not functioning properly. Within the alexa app, it is showing C instead of F and just doesn't function properly. This is only in the Alexa app. Within the 'SmartLife' app for the thermostat, it works perfectly fine. Very happy with the result and install. If it helps someone, on my Coleman that had those wires above:
Red 12V DC Positive - TO RH
Blue 12V DC Negative - TO C
White Furnace Control (Heat) - TO W1
Yellow Compressor (AC Cooling) - TO Y1
Green High speed fan - TO MULTI
Grey Low speed FAN - TO G

  • Can The Coleman-Mach WiFi Thermostat CM46MR Control Two Separate AC Units?
    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...

  • Does the Coleman-Mach WiFi Thermostat Reduce Temperature Swings?
    Hi Jim, that's a great question. Yes, the Coleman-Mach WiFi Thermostat part # CM46MR does give you more control over how often your furnace and air conditioner cycle by using a Cycles Per Hour (CPH) setting instead of a fixed temperature differential. Increasing the CPH tells the thermostat to check and react to temperature changes more frequently, which typically results in smaller temperature swings and a more consistent indoor temperature. In other words, it doesn't adjust hysteresis...

  • Recommended Mach 8 Plus AC w/ Heat Pump and Components to Replace a Coleman Mach 10
    You sure do Thomas and good morning to you as well. The Mach 8 Plus units do indeed require a air distribution box or trim on the interior of your Grand Design. To replace your three Coleman Mach 10 15K AC units, you will need the following parts and the quantity listed next to them: Qty 3 item # CM74MR in black or item # CM95MR in white - Mach 8 Plus RV AC w/ Heat Pump Qty 3 item # CM48GR - Coleman-Mach CHILLGrille Ducted Ceiling Assembly or item # CM98GR if your Grand Design has a ductless...

  • Can Multiple Coleman Mach AC Units Be Controlled By Wireless Thermostat In RV?
    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...

  • Will The Coleman-Mach WiFi Thermostat CM46MR Work For Controlling AC And A Furnace?
    Hello James, thanks for reaching out. Yes, the Coleman-Mach WiFi Thermostat # CM46MR will work with your setup. It can control rooftop A/C units along with your propane furnace, so the fact that your heat source is propane instead of a heat pump isn't a problem. The thermostat supports both furnace and heat pump applications and will operate whichever type of heating system your RV is equipped with.

  • Coleman-Mach WiFi Thermostat Compatibility
    Thanks for letting us help Aaron. Yes, since you are using the Single Zone Digital Thermostat # CM76RR currently, the Coleman-Mach WiFi Thermostat # CM46MR will work as an upgrade. The # CM46MR is designed for Coleman Mach single zone A/C and heat-pump systems and uses conventional 12V thermostat wiring. The # CM76RR is a digital wall thermostat, so you already have the control setup needed for the # CM46MR. You will just need to move the individual thermostat wires from the existing...

  • Coleman Mach CM46MR Thermostat Operation Without Wi-Fi
    Hi Gary, The Coleman Mach thermostat part # CM46MR will still operate your RV’s heating and cooling system manually without a Wi-Fi connection. You can adjust the temperature and switch between the available modes directly from the thermostat’s physical controls, so you will still have basic climate control if the Wi-Fi goes out. The main thing you lose without a network connection is the smart functionality, such as controlling the system from your smartphone, making remote scheduling...
