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

Product Information

I then connected the blue wire to a 12 VCD(-) connection at my heater, and directly connected that to the control box. So, as I am learning more, I think what I am pondering is whether or not the blue has any purpose in the functionality of the A/C, or is it just there to close the loop on the t-stat. 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.

Zones can be turned on or off individually to save propane, electricity and money, so if you're spending more time in the front of your RV on a hot summer day, you can maintain a more comfortable temperature there and leave it warmer in unused areas. I bought this TStat a long time ago based on a post here and have since misplaced/lost instructions. As you can see in this outback owner's post, the trailer wire colors have nothing to do with the thermostat standard colors. For example, if you have an 8xxx series control package, you cannot use that control kit with this 9xxx series thermostat. Soooo, on this Laredo the four wires in the bundle coming from the air conditioner worked out to be.

Control your RV air conditioner, gas, or electric heat strips and fans from one convenient location. I guess in those cases either their control box did not require that ground, or that wire was elsewhere grounded and still supplied connection to the control box.

The Easy Touch T-Stat brings modern touch screen and Bluetooth technology to your RV, making your RV living more comfortable. PHP, but I also wanted the separate gas/electric heat settings, since I also installed the electric heat kit in my AC unit. I am being given a green cheek conure in a month and my thermostat is in the worst location, almost 7 feet from the main floor on the stairs to the bedroom.You will need this information to provide to your dealer for selecting the correct Bluetooth T-stat.
