Can the non-ducted Coleman Mach roof mounted air conditioners with the manual knobs be converted to a wall thermostat system? I like the quiet when the AC cycles instead of the steady fan noise.
1. Install a Ducted AC inside plenum 2. Purchase a Wall tstat and Upper wall tstat control board kit 3. You will have to run a 6 to 8 wire standard AC wire cable from the AC unit to the area on the wall inside the motorhome where you want the Tstat to sense the interior air. You will also have to run a Ground and Positive 12 volt source to either the Roof AC or the wall tstat to power the system. Doug
