Question Coleman Mach Thermostat

Hi, I have a Coleman Mach thermostat and will be using the heat for this weekends camping trip. The question that I had was should I set the fan to Auto or On? The Auto has a Low & High option and the On position also has a Low & High option.
My camper is a Rockwood Roo 21SS 2012

Thank You

Does your Coleman Mach have a heat element in it? It is an option so you just might.

My Coleman Mach thermostat does control heat but just the thermostat turning the furnace on and off. The furnace fan only has one speed and it is 12 volt DC (not 120 volt AC like the air conditioner).
