We splashed on Friday and it's been decently warm (70s) but last night it dipped into the high 40s. I went to turn on the heat down below and the room temp display says 85. Then the A/C kicks on. At this point it was about 65 in the cabin. Not had this happen before. Tried turning off the power to the unit and trying again. Same thing. I was thinking of doing a reset on the thermostat. Any other thoughts?
