Thermostat Problem

FIXED. LATEST UPDATE
This is good information. The tech talked me through this on the phone. The thermostat is Coleman Mack. This fix applies to manual or digital box. Take cover off, take out fuse, there is only one, leave out 5 minutes. The unit reprograms it self. ,put fuse in, now works. Thanks for the response

Coleman Mach to Honeywell Digital T-stat....ones that use AA Batteries

Coleman Wiring

Red = +12vdc
Blue = -12vdc
Green = Fan High
Gray = Fan Low
White = Furnace
Yellow= Compressor

Coleman to Honeywell

Red = +12vdc -----'RC/RH'
Blue = -12vdc NOT USED/Tape off
*Green = Fan High ----'G'
*Gray = Fan Low ------'G'
White = Furnace .....'W'
Yellow= Compressor ,,,,'Y'


*Green and Gray are used for the A/C Unit fan speed
If you do not install/modify your thermostat with a mini switch to have/use both Hi-Lo fan speeds just connect GREEN (Fan High) to 'G' terminal
