The temperature must be present for at least a certain pre-set time for
the output to switch on. The output does not immediately change its

If the switching event is no longer present after the delay time, the
switch output does not change.
The output only switches back when the temperature has fallen down
to the reset point (PR) and stays at or below the reset point (RP) for at
