I want a digital Bluetooth thermostat to run the heater. Dometic tells me that their Bluetooth thermostat for both heating and cooling will work with a heater only if set up in the right way. My local RV guy tells me he thinks that you need an ac to run some of the wiring, and it would not work with a heater alone. I am willing to spend the money to buy a dual thermastat for a heater only, if someone has knowledge about whether this could work and how. Anyone know about this?
