Options:
This parameter defines an additional function for this lighting group.

None: This lighting group operates as a "normal" group of the DLR/S 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/S or a second KNX device. In this case, data is
exchanged via KNX with communication objects. The
enabled. The properties of the slave lighting group are parameterized in this window.

Light control: The lighting group performs light control. The brightness value of the lighting group is
calculated according to the brightness detected via the light sensor, so that the luminance (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. Refer to

on and off via the Function Activate controller communication object. Accordingly, energy efficient
building automation with optimum brightness during occupancy can be generated, together with the
use of a presence detector.
