Minnesota Oli I am in the process of changing from a Dometic A/C to the same unit you just installed. I see you also installed the easy start for your unit. Can you maybe provide a wiring diagram on your install? It looks like you may have made brackets to hang the easy start on? I see a junction box for the wires. Did you add that? I installed the easy start on my last a/c but it had a diagram to follow. I don’t want to screw up a new a/c so I would appreciate your expertise. Thanks.
Thermostat issues for heat can be resolved using a Honeywell Pro TH 1100DV1000 thermostat. Intercept two wires that come from the furnace to the Dometic a/c control box and use two of the wires that go to the current Dometic digital unit and attach them to the Honeywell unit. The Honeywell uses double A battery that you change once a year. The thermostat just makes and breaks the connection when you call for heat and the Honeywell unit is not very expensive.
