Question:
I have a Duo-Therm Model 57915.522C1 with a Part 3107541.009 control Board, that need a thermostat for. Nothing fancy just one to make the unit turn on and off. Thank You Kenneth

To replace your Dometic Thermostat you will want to use the Replacement Single Zone Thermostat for Dometic RV Air Conditioners item # DMC79FR you were looking at.
I have attached a wiring diagram below to help you get it set up.
