(Note: Unit set point range is depending on unit e.g. 5 till 20°C.
In some user interfaces, it is possible to change the set point range towards the user e.g. 10 till 15°C.
But these values are independent from the unit set point range. Meaning unit set point range values are
not modified. E.g. 5 till 20°C)
