We wanted to thank you for the feedback regarding the heater pump. We are still a bit confused however with this statement: "BTW The bottom position on the SYSTEM switch should make the CoolCat heatpump function run."
So which thermostat setting is needed to make the unit work so we can heat the trailer? "Heat Pump" or "Furnace"
And secondly, if only one works, what's the point of having two options?
