Gotta Be Nuts
Hello, I am getting close to finishing my DIY Webasto furnace install. I say DIY because I bought the standard diesel truck coolant heater and have collected the parts needed. I have pretty much everything installed and am now wiring. Our heater came with a simple 3 wire lit toggle switch for turning it on/off. There is a red/black and brown wire. So now I want to hook this to a standard household thermostat (Honeywell th1010d2000). I know these same furnaces are used on smaller boats and use a thermostat (which I could have bought the package at a much higher price than what I have assembled). I think from the wiring diagram I need to use the black and brown wires for the thermostat and ignore the red as I think it was just used to light the switch when operating.
