We have a 2018 Raptor 428SP. This unit has 3 ACs and one controller. When you scroll thru to turn off the AC and turn on the heat there is option to select gas or electric. At first I thought awesome ... I can save my propane. Tonight I turned the unit on and selected electric. A short time later the flame symbol popped up and the gas furnace kicked on. The overhead units also come on at the same time. Plenty of heat come out of the floor but cooler / cool air come out of the overheat units. No heat ever come out even though electric was selected. The garage is still running and no heat.

If there is a selection for electric why does the gas furnace come on? If there is a selection for electric doesn’t that mean the overheads should produce heat or is a heat strip needed? Or is that supposed to be a heat pump? Someone suggested these had heat pumps but I don’t think so.

Any help understanding how these systems work is appreciated.
