Originally I had it in my house, and it seemed to "honor" the thermostat setting, but the room at home is a lot bigger than the cabin of my trailer.
I know the mass of the oil makes the response slower than a forced air type heater.
Thinking about it more, my new plan is to put a digital thermostat and relay in a box with an outlet and a short cord to plug into the wall. then I can plug the heater into it. That was I don't have to modify the actual heater itself, I'll just turn the tstat to max and let the external thermostat turn it on and off as needed.
