Function light control after download
or KNX bus voltage recovery
Options:

not activated: No function is carried out after download or KNX bus voltage recovery. The lighting
group assumes the parameterized brightness at DALI bus voltage recovery. The control is
deactivated, the lighting group is a normal DALI lighting group without additional function.

After a download or a KNX bus voltage recovery, the lighting control 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 bus voltage recovery or after a download in the parameter window
Parameter window - Gx

activate and ON: Lighting control is activated and running after download or KNX bus voltage
recovery, i.e. the lighting group immediately commences with control immediately after download of
KNX bus 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 a lighting control has been implemented.

previous state to malfunction: After download or KNX bus voltage recovery, the lighting group
assumes the state before download or before KNX bus voltage failure, i.e., if the lighting group was
controlling beforehand, it will continue with control at KNX bus voltage recovery. If control was
deactivated, it is deactivated again after 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 lighting control is not transferred on the KNX.

yes: via object "Activate fct controller/status": With the communication object Activate fct
controller/status it is possible to not just activate or deactivate control. This communication object also
uses the status to display whether the control is active or inactive. The following parameter appears:

Send
Options: after a change
after request
after a change or request

after a change: The status is sent via the communication object after a change.

after 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.
