Via this communication object, the relative dimming telegram is received for the respective lighting group. They are dimming
telegrams BRIGHTER, DARKER and STOP. After a start telegram is received, the brightness value is changed in the defined
direction with the parameterized speed. If a STOP telegram is received before the dim process ends or the maximum or
minimum dimming value is reached, the dimming process is interrupted and the received brightness value is retained.
If the dimming values are above or below the max. or min. dimming values (dimming thresholds), the respective dimming
threshold is set.
This communication object is not available with a parameterized additional function.

A defined brightness value for the corresponding lighting group x is received via this communication object. Any elapsing burn-
in time currently active has a higher priority, so that under certain circumstances individual devices can only assume a
brightness of 100 % or OFF.
In Parameter window Gx
a dimming speed.
If the brightness values are above or below the max. or min. dimming values (dimming thresholds), the respective dimming
threshold is set.
Telegram value:
It is possible to parameterize that the status of the brightness value is fed back via the communication object Brightness
value/status. Generally, a separate communication object Status brightness value is used. This can be enabled in
window – Gx

This communication object is enabled if in
brightness value of the lighting group is set with the option yes: via object "Brightness value/status.
This communication object has the same functions and characteristics as the communication object Brightness value. The
status is additionally fed back. Additionally, the value of the communication object is also updated if this is not sent on the
KNX.
Telegram value:
Note
If several KNX group addresses are assigned to the communication object Brightness value/status, the status
address should be set as the sending address.
In a KNX group with several status messages, it is useful to allow just a single group member to feedback the
status.

This communication object is enabled if in
brightness value of the lighting group is set with the option yes: via separate object "Brightness value/status.
Telegram value:
This communication object reports back the current brightness value of the lighting group. The value of the communication
object updates itself during a scene dimming process or sequence.
It is possible to parameterize when a status telegram is sent. The status can be sent after a change and/or after request.
