Hummel Premium - Restoring the Factory Settings; Setting the Offset Temperature

23. Setting the offset temperature
The temperature is measured at the heating appliance itself, with the
result that other parts of the room may be warmer or colder than this. To
allow for this, you can set a temperature offset of ±3.5°C. If, for example,
a temperature of 18°C is measured somewhere within the room instead of
the 20°C set, it means that an offset of -2.0°C needs to be configured.
