It sounds like we have the same controller….and yes, I've selected "FURN" and both the HP and FURN run. That only happens when I'm plugged in to shore power. If I'm off shore power, then it's just the furnace that runs…as it should.
New Dometic CCC-II and single zone thermostats are programmed to operate the roof unit fan
, but not the compressor whenever the gas furnace is on. You can avoid this by selecting 'auto' for a fan setting, as this will allow for the operation of the furnace ONLY.
Dometic dod this to help circulate the hot air rising to the ceiling from your floor ducts back thru out the RV. Most of my clients prefer the furnace-only option.
