Select additional function
Options:
This parameter defines an additional function for this lighting group.

none: This lighting group operates as a "normal" group of the DLR/A without additional function. It can
be switched, dimmed or controlled with a brightness value.

slave: This lighting group is defined as a slave. This slave lighting group is forcibly operated by a
master. This can be another lighting group in the DLR/A or a second KNX device. In this case data is
exchanged via KNX with communication objects.
In these windows, the properties for the slave lighting group are parameterized.

light control: The lighting group undertakes lighting control. The brightness value of the lighting group
is calculated in dependence on the brightness detected via the light sensor, so that the light density
(brightness of the surface underneath the light sensor) detected by the light sensor remains constant.
The setpoint value should be set via a commissioning routine with artificial and daylight calibration.

and off via the communication object Activate function controller. Accordingly, an energy efficient
building automation with optimum brightness during occupancy can be generated together with the
use of a presence detector.
Note
Other functions such as staircase lighting, blocking, forced operation and characteristic curve
adjustment are enabled in Parameter window - Gx Functions, page 82.
