Meaning
Specifies the buffer zone
between the set values for
heating and in cooling

With a switching (2-point)
control, the dead zone is
increased via the
hysteresis.

The heat protection
represents the maximum
temperature permitted for
the controlled area. With
cooling it fulfils the same
task as the frost protection
mode during heating, i.e.
save energy and at the
same time prevent non-
permissible temperatures.
