I need a little help. I tried using diagrams that are online and cant get my unit to work. I have posted pics of the previous thermostat how its wire. Can someone tell me where I need to put what color to make it work? Thanks

Do you have a Mach 3? I made the mistake of wiring up a new digital t-stat using the wrong (Dometic) wiring diagram.

I have a Dometic AC unit trying to wire up at Hunter non programmable thermostat. Not sure what a Mach 3 is.

That is a digital you are replacing- will not work. There is no option for that other than replacing the electronics in the roof unit.

Is it a Dometic digital you are replacing?
Not sure that is compatible with a home unit.
