I have a certain device located outdoors. It contains a power supply which, according to the manufacturer, can operate from -10°C. I want to protect it from switching on below this temperature. Are there any bimetallic thermostats for such low temperatures? Electronic ones tend to fall out as they require a power supply and I want to cut it off below this temperature limit.
I also don't want to permanently connect a 230V heater, because why should it heat non-stop.
