in IO Setup e. g. for controlling a Heating.
If the ambient temperature is lower than the set operating point, the heating remains switched on. If
the ambient temperature exceeds the set operating point of the heating by 2 K (Kelvin), the heating is
switched off. I.e., the release point is situated at the hysteresis value over the operating point.

If the ambient temperature is higher than the set operat-
ing point, the cooling remains switched on. If the ambient
temperature falls below the set operating point of the
cooling by 2 K (Kelvin), it is switched off. I.e., the OFF
point is situated at the hysteresis value under the ON
point.
