Mine is the "8KW" type, which was about the same price as other sizes in the same all-in-one box configuration.
There is a Facebook group "Diesel Keep You Warm..." that has some manual pdfs.

I'm pretty sure the controller on my heater allows it to be thermostatically controlled. (in C, no F).
I 'think' there is a heat sensor (thermistor) in the panel.
Mine is set up to use the fuel pump rate, because it allows me to control fuel use.

I've been thinking of buying another one of these for the kids.
They have a real nice house, but no fireplace! Zero heat backup.
(I don't think they have any sleeping bags)!
A diesel heater might keep their house from freezing up and it's a lot cheaper than a Power-Wall.
