or blocked
Receive manual set point offset.
The object receives a temperature difference.
The desired room temperature (current set point) can be
adjusted against the base set point by this difference.
This applies in comfort mode (heating):
Actual set point = base set point + manual set point offset.
Values outside the configured range are limited to the highest
or lowest value.
If a 0 is received, a set point temperature offset that was
previously entered is reset to 0.
The offset always refers to the set base set point and
not to the current set point.
