When the ambient temperature outside is, say 45, the emergency heat kicks o n. And it stays on for a long time. I know because I check the Energy Tra cking and there is a lot of usage under "Electric Heat" (as opposed to Heat Pump). I would have thought this would only happen if there is a real disp arity between indoor and outdoor temperatures.
Our installer says that the only way to fix this is to completely disable t he emergency by selecting "heat pump only" in "Heat Source" on the thermost at. Surely that isn't the design of the system, is it? Any suggestions.
