Function light control after download
or KNX bus voltage recovery
Options:

Not activated: No function is executed after download or KNX voltage recovery. The lighting group
assumes the parameterized brightness at DALI bus voltage recovery. The controller is deactivated,
the lighting group is a normal DALI lighting group without additional function.

Activate standby: After a download or a KNX voltage recovery, the light controller is activated and in
the standby state, i.e., the controller starts with control after an ON telegram or re-activation of the
control via the communication object. Until the start of control, the lighting group has the brightness
value that has been parameterized for KNX voltage recovery or after a download in the
window - Gx

Activate and ON: The light controller is activated and running after download or KNX voltage recovery,
i.e. the lighting group immediately commences with control immediately after download of KNX
voltage recovery. Commencing at the switch-on brightness, the lighting group controls the room to the
setpoint brightness, independently of whether the lighting group was switched off before failure or
whether light control has been implemented.

Previous state to malfunction: After a download or KNX voltage recovery, the lighting group assumes
the state before download or before KNX voltage failure, i.e., if the lighting group was controlling
beforehand, it will continue with control at KNX voltage recovery. If control was deactivated, it is
deactivated again after the failure. After the first download, the controller is active and is in standby.
Status response of function Light
controller
Options:

No: The status of the light controller is not transferred on the KNX.

Yes: via obj. "Fct Activate controller/Status": The communication object Fct Activate controller/Status
does not just activate or deactivate the controller. This communication object also displays the status
of whether the control is active or inactive. The following parameter appears:
Not activated

Send
Options: After a change
On request
After a change or request

After a change: The status is sent via the communication object after a change.

On request: The status is sent after a request by the communication object Request status
values.

After a change or request: The status is sent via the KNX when the status changes or the
status is requested via the communication object Request status values.
