Using this communication object, the offset for the master/slave control is activated or deactivated. In this way, for example,
the offset is switched off (deactivated) or switched on (activated) at a determined level of external brightness or by a timer.
With deactivated offset, the slave is controlled with same brightness as the master.
On activated offset, the brightness value of the master has the parameterized percentage applied and the provided to the
slave via communication object Master: Brightness offset

Using this communication object, the internally set variables (control parameters) in the DALI Light Controller can be read or
defined for the current setpoint.
Hereby, different setpoint settings for lighting control can be set for various applications, e.g. for competition and training
settings in sports centers. The procedure is described in
It is inadvisable to transfer control parameter settings for a setpoint from other rooms, as it is practically excluded that both
rooms have exactly the same reflection properties and brightness relationships. Furthermore, the characteristic, which
controls the lighting, is determined during the automatic artificial lighting calibration. If control parameters for a setpoint value
are still transferred regardless of these facts, it must be assumed that the light control will be inexact (large setpoint
deviations).

Note
This communication object can be read and written in the ETS.
However, the value of the communication object is not sent automatically on the KNX by the DALI Light
Controller, regardless of whether the T flag is or is not set.
