This parameter defines the brightness value for the Turn off brightness function, i.e. the brightness
at which the ballast, group or output switches off when it receives an OFF telegram.
Values set outside the thresholds (maximum brightness/minimal dimming value) are automatically
adjusted to the maximum or minimum.

"Activate fct Turn off brightness"
(enable in "Output functions")
Options: Yes
No
Turn off brightness can be activated/deactivated via the KNX using the Activate fct Turn off
brightness group object. This means a timer can be used, for example, to set the lamp to a
parametrizable turn off brightness at night instead of switching it off.
•
Yes: The ballast, group or output evaluates the Activate fct Turn off brightness group object.
If the gateway receives a telegram via this group object on the output, the system reacts as
follows:
1: The turn off brightness is set to the parametrized brightness value. The Turn off brightness
function is activated. An OFF command will then apply this brightness value instead of
OFF, 0%.
0: The turn off brightness is set to 0. The Turn off brightness function is not activated and an
OFF command switches the system off via the Switch group object, applying a brightness
value of OFF, 0%.
•
No: The ballast, group or output does not evaluate the Activate fct Turn off brightness group
object. The system always switches off at the parametrized turn off brightness.
