Local setpoint shift

If setpoints are shifted locally and corrected by the controller, local shift is applied.
Two methods are available for local setpoint shift:
– Using a series QAX... room unit (local PPS bus) providing a rotary button or rocker
switch to adjust the room temperature setpoint
– or via EIB/KNX bus.
If multiple sources command local setpoint shift, "last one wins" applies.
The S-mode communication object is used for setpoint shift via the EIB/KNX bus:
Setpoint offset (input communication object)
