Dometic CCC2 thermostat

Has anyone changed out the piece of crap Dometic CCC2 thermostat with something easier to set and program.

IF yours is like mine the connector to the A/C unit is a RJ11 plug. If you look at the schematic for the control unit where the RJ11 plugs into there is no disclosure of what the four wires go to in the controller. It just show it plugs in and then a miracle occurs and the A/C unit works.

Originally, we set ours up with the clock function and the auto set back feature. After struggling with it, we reset it, just use it manually, and it works great. We set the temperature in the morning when we get up, then again at night. We didn have a problem with the display going weird. Just ordered a new one and set it up. Trouble is, if you want to change it, you will also have to do something different at each air conditioner unit, as there is a control box that works with the thermostat.

I had two E1 error codes the other day. Had to do a complete reset, unplug power and disconnect battery for 20 minutes. Fortunately got one AC working to last through the day and took it to dealerships the next day. Haven't heard from them yet.
