Heat pump question

Have a 2020 Canyon star 3710! 15K heat pumps.

Got home Monday, from a week at the Tampa RV Super Show/Newmar Rally!
Everyone was hooked up to 30 Amp for the week. Temperatures cooled down, so we ran the front heat pump. Actually used the furnace for two nights.

RV is in the garage, & plugged in to 50 amp service. HVAC front & rear are in the "OFF" position. Yesterday afternoon, DW says she hears something in the garage. I go to check, dang front heat pump is on "heat", just a pumping warm air! WOW! I turn it "OFF", and double checked the rear as well! All were "OFF"!

Just about 30 minutes ago. open door to garage to take out trash; surprise!!
Front heat pump running and has the coach at a toasty 72 degrees! As I said, yesterday I double checked and it was "OFF"! Turned it to "OFF" and set the temp down to 60 degrees! Was at 72 degrees.

So, what could be causing the front "Heat Pump" to come on by itself??
Ghosts, Gremlins?? I think not, but there's some funny "electrical" stuff going on!!

HELP!!

And THANKS!

Do you have a program in your thermostat set to run at a certain time?

Sometimes these things do weird stuff. You might simply try rebooting everything, as in turn off the power in the coach, (sales man switch) wait a minute and then trun back on. Be sure to double check your settings again as reseting them may change the settings to factory default.

On my old coach, the thermostat would occasionally reset itself and the factory setting was 72 degrees. It had something to do with a voltage issue when the batts got down to resting voltage around 12.0. I'm not familiar with the t-stat in your coach, but it sounds like it's completely digital and it might be doing the exact same thing. Then again, it might be as simple as killing power to everything and waiting a few minutes for it all to reset.

You may have some sort of program set in your thermostat. I donít think it will run a program if the thermostat is set to off but, stranger things have happened. Go into the thermostat manual and make sure to clear out all programs.

Try resetting the thermostat (instructions in manual), resolves many odd issues.
