dometic 2 zone thermostat

[Yxdguy]

Hi new here. so I have one 2 zone type thermostat ( it does not have heat strip setting) all this controls is the furnace and 2 ac units in 5th wheel 2017 Sanibel. so what are the best settings to use for this type of thermostat I thought I had it all programmed but nope 2 am it got chilly to say the least in the trailer I been told to use it with the fan switch set to on and auto settings all the time any tricks or ideas to use it properly or should I look at different type of thermostat.
thanks in in advance.

Zone 1 on the Sanibels is for the furnace, and living area A/C unit. Zone 2 controls the bedroom A/C unit. I personally don't use the programming function & can't help you there because I don't remember how to.
If it's cold and you want just the furnace function;
Zone 1 should be on Furnace, fan off & temperature set (up & down arrows) to your desired temperature.
Zone 2 should be OFF

In this configuration, the furnace should cycle in & off to maintain the desired temperature you set.

Thank you
I have a copy of how to program just not sure if it is the best option they give.
thanks for reply

Just one change....I mentioned above that the fans should be OFF. Actually, on the fan settings there is only Lo, Med, Hi & Auto. Set them to AUTO or else the A/C fan will run.

The Dometic CCCII Thermostat on my motorhome has two zones. I've never been able to get it to work without programming it. I've never found instructions on how to do this and playing with it never worked.

One of the big gotchas is that if I take the unit out of storage, the thermostat clock is dead. It remembers the programs, but won't run anything until I reset the clock.
