We spent our first night in our FR EVO T2300 - love it!
But since it was freezing cold outside, we ran the heater for a while. I set it to 65F like I would at home. But it just kept running, and running and running... until the kids were frying! So I thought I'd turn it down. No effect. Down some more. Nope. I had to turn it down all the way to 45F to get the heater to stop!
So the 'hysteresis' built into that thing must be way off. Or else the temp gauge must be inside a closet, who knows. Brand new RV, and yes I did check the AC and Heater during our PDI but I certainly didn't check the temperature control range.
What to do? I don't want to go all the way back to the dealer for warranty work. The stock thermostat isn't that great anyway, it only has options for Fan/Heat/AC anyway and doesn't show the ambient temperature. And fan is always on Hi.
Is there a good replacement? Can I used a household thermostat here or must it be a $pecial RV model?
Original looks just like this:
