Convert Dometic Manual Knob control to Thermostat

[rbreding]

I know there are other ways to use relays to accomplish the same thing but I kept looking for a factory solution to convert my rooftop control knobs to a wall mount thermostat instead. I came across this control module from dometic but wasn't sure if this was correct (model # Dometic 3312020.000).

I have a Brisk II Polair Air 15k (b59516.711c0) model for reference.

Input welcome...thanks

I believe this will work. Even if you don't have the heat strip it gives you the ability to add it later. The 3312020.000 is a multi zone control for a units with 2 or more a/c .

Thanks. I looked that one over pretty good and it looks like it will run the propane furnace also ? So replace the heat thermostat with this one to control the A/C, heat strip, and propane furnace ?

That would work. Otherwise you have 2 stats on the wall . You will have to chase a 3 wire stat cable from the a/c to the t-stat location .

I don't have an issue fishing in the cabling. I have been doing that with several mods over the last two weeks.

Thanks

Another thought I had but need to clarify is this thermostat makes you select from your A/C heat strip and your propane furnace for control. Obviously if you have shore power and want to use the electric strip to supplement your furnace you couldn't unless you had the furnace on a seperate thermostat correct ?

Correct
