so it comes when the ambient temp is 35* thenAerospace Eng;2068253 said:There is a thermal element in the "cube" that you plug into. Basically when the cube is above a certain temperature, it switches off the output. When the cube is below a certain temperature it turns it on. So the cube needs to be outside.
It has nothing to do with the temperature of the element, which may have additional built in thermostats. I use similar ones to control heat tape on water spigots.
