Coleman Mach 9630A3361 Wall Mount Digital Thermostat-12 VDC, Single Stage, Black

Product Information

The other bundle heads to/from the A/C and will consist of a ground (usually blue), cool (usually yellow but you don't have one), fan low (usually gray, again you don't have) and fan high (usually green). Below, we have provided a list of Coleman Mach thermostat part numbers to assist in selecting the correct Bluetooth Thermostat. The Coleman Mach Thermostat is a single stage heating and cooling wall thermostat with a digital display.

A/C -> blue wire to t-stat - this is labeled as 12 VDC(-), and then the diagram shows that there should be a 12VDC(-) connection to the t-stat. ZC zone control thermostat, you can control up to four rooftop air conditioners or heat pumps, plus four zones of gas, hydronic or electric strip heaters and fans all in one location! Please Note: Your thermostat may contain an additional number at the end of the part number such as a 1, 2, 8, or 9. It wasn't too hard to install - just follow the instructions and look at the spec sheet online for the Honeywell. Current wiring to the thermostat consists of a single red and single white wire coming off of my heater.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. Please do not use with any other application other than that which is specified in the installation and operating instructions.

On the top of ScottG's photo above, it looks like the labels are silk screened in white behind the wires. I currently have a Coleman Mach Model AR7815 and would like to upgrade to a digital but not sure which one so I thought I would ask from those who have done it and get your thoughts. This Coleman Thermostat is simplicity at its best, providing complete control of your air conditioner, heat pump, gas, hydronic or electric strip heating and fans from one convenient wall thermostat. It stands alone in the world of recreational vehicles as THE smart thermostat available in the aftermarket, enabling WiFi and Bluetooth cabin comfort control. I did not use two of the wires from the existing trailer system to this new one which are for the hi/lo fan settings.

one set were people adding the control box to a Coleman-Mach t-stat in which case the t-stat had a connection for the blue wire.
