The problem ended up being a connection that had come loose on a wago style connector behind the electrical control board, I finally found out where all the wiring went ! I would like to replace this out with an thermostat that has the AUTO feature so that it would switch from heat to AC as needed depending on the set temperature. This digital, multi-zone thermostat can control up to FOUR (4) rooftop air conditioners or heat pumps, plus FOUR (4) zones of gas, hydronic or electric strip heaters and fans from one location!

I had my Lux battery operated digital programmable t-stat laying around from when I switched over to Geothermal and installed it the other day.I then connected the blue wire to a 12 VCD(-) connection at my heater, and directly connected that to the control box. You will need this information to provide to your dealer for selecting the correct Bluetooth T-stat.

Please do not use with any other application other than that which is specified in the installation and operating instructions. Below, we have provided a list of Coleman Mach thermostat part numbers to assist in selecting the correct Bluetooth Thermostat. granted, probably not the same 2 you're asking about, but maybe some of the "wiring" info might be helpful. When I did some work at home here the thermostat instructions explicitly said the blue wire must be connected. Keeping all RVer's in mind, Coleman MACH has made it simple for larger RV's with multiple sources of heating and cooling to control it all by connecting to one single thermostat.Note: This thermostat is generally specific to the appliance it is being used with and is not universal. I saw one thread where someone actually installed the exact same thermostat from an analog t-stat that already had A/C control. A few years ago, in my 2008 Wildcat I tried to change from Dometic analog thermostat to a Coleman Mach digitial just like you have pictured.

Pair up to 3 Thermostats to a single smart device Connect up to 4 smart devices to control thermostat operations For iOS and Android devices iOS 9.The Coleman Mach Thermostat is a single stage heating and cooling wall thermostat with a digital display. Most (All that I have found) Residential thermostats are powered by 24vAC from the Furnace and send out a 24vAC signal to power on the Furance or AC.
