OK, I am an idiot. I am getting a crash course in winter camping, since I am in snow and below zero temps for the next 24-36 hours. I thought the heat pump was for heating the water tanks, but the service department said it helps my heater run more efficiently?? How does that work? Also my panel has three switches on it for heating the three water tanks, the fresh, grey and black. So I felled the fresh water tank, and turned on all three switches for now! Still curious how to use the heat pump to make my heater more efficient, and why is it only on the bedroom controller?
