Newbie question:
How does one cycle between the heat pump and furnace?
On shakedown trip now, it was chilly around 40 last night. I realize this is the end point for heat pump to work. However, our rig is firing up the furnace for heat every time, not heat pump at all.
I understand there’s a way to set the Coleman Mach unit to run heat pump preferred first, and then furnace as a backup.
I checked control panel, thermostat, etc - no obvious answer like with the water heater!
How/where does one configure this?
