Propex HS2000 thermostat: temperature setting chart

I just installed a Propex HS2000 heater in my truck camper and fired it up for the first time yesterday. The fan noise is a little louder and hi-pitched than I thought it would be, but it seems to sip propane pretty slowly and draws 1.8A @ 12v when running. It’s exciting to have warm air flowing in the camper!

One of my goals for the heater is to be able to keep the camper from freezing while i’m out all day doing an activity in cold weather, but not burn a ton of fuel in the process. Luckily, it looks like the thermostat that comes with the unit has a wide range of settings to allow it to maintain an indoor temp minimum of 39.2 degrees F. (4 degrees C). I’ve mounted a second thermometer with a temperature probe set right at the thermostat in order to see what the comparison is between the two. Here’s the chart for the temperature settings. I’ll report back later after some more use.
