CapnDean Posted November 14, 2022 Share Posted November 14, 2022 (edited) 2008 Camelot 42PDQ. I have triple roof units for AC as well as floor registers and even bay temp control. I understand some of the logic. But not all. If I select heat pump on the thermostat, my ceiling units do a good job keeping my coach comfy except when its too cold for the heat pump to be efficient. I understand that I need to choose furnace heat in this situation. Q1) Will the thermostat make this decision for me? Or must I physically get out of my warm bed and tell the thermostat to go to furnace mode? Generally when staying aboard at an RV park, I select "electric" mode for the AquaHot. It does well enough for 2 showers and dishwashing etc. I prefer not to use diesel fuel when I can use park electricity. Q2) Should the AH be able to support furnace action without the diesel burner? I think that the electric element is only 1500W and I just dont see how that would be enough to heat the coach. Q3) Is there a way to adjust the "kick on" setting for the diesel burner so that I may use electric and only use diesel when electric is totally overburdened? If I am on diesel & electric... the diesel burner seems to take over a lot sooner than I would like. (E.G. I am shaving in the lavatory and by turning in the hot water a few times....I hear the diesel burner kick on). and lastly.... i understand that the AH will use engine coolant heat to operate while I am in motion. When I select "Engine preheat" mode on AH.... I get that it is trying to heat the engines cooling water.... Q3). Does it have any method of circulating it? Or am I just sending a warm gallon or so of coolant to the engine when I start it? I appreciate any input from those wiser in these devices!
