Question Can temp diff be adjusted?

Can my Dometic AC be adjusted down to a 1 degree differential? It looks like 2 degrees is fact. Default

Nope. Unless you have a non thermostat one.. with a dial..
Edit.. there is a problem with cycling the compressor too quicky

Hi

There are a *lot* of HVAC systems set up to cycle at about 4 degrees. Two degrees is actually "fast" by the standards used in a lot of places.

Go to a one degree differential and you are going to cycle the compressor on before the head pressure has equalized after the last shut off. Not good. Not good at all.

Pretty sure my Firefly controller is setup at about 3 or 4 degress as UNCLEBOB said. And I remember reading the Dometic CCC2 is set to 2 degress.

Agreed. Do not see how a 1 degree benefits anyone/anything. It would be asking for trouble.

Thumbs up Thanks all

Great scoop folks .....really appreciate the info.....Dometic peformed flawlessly during 3 days of NOLA temps......HI 100+ everyday. We did buy a small 110v fan that we placed between the front seats to enhance circulation.... and for some "white noise" during AC "resting" periods
