Temperature variation with factory setting
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.
Example:
Setpoint 15.0 °C, Offset +5.0 K, Hysteresis 2.0 K
ON = 15°C + 5 K = 20 °C

OffsetDigitalOut
Offset Digital Out = Offset for relay output ("K2" is pre-programmed by the factory).
The relay operating point deviates by the adjusted offset of the Setpoint of the ventila-
tion (if relay "K2" not inverted, terminal "21"-"24" bridged).
