Overwrite scene on download
Options:
When a download occurs, the parametrized scene values are usually transferred to the gateway. This
parameter can prohibit the transfer so as to prevent manually set scene values from being overwritten.
Instead, the scene values saved via KNX are retained.

Note
When a scene is recalled or stored, only the ballasts or groups in that scene are taken into
consideration.
Jump to: When a scene is recalled, the scene members are switched on immediately at the set
brightness value of the scene.
0.7 s...90.5 s: When a scene is recalled, all the lighting scene members are dimmed from their
current brightness value to the set brightness value within this time.
Via object "Flexible time for dimming/fade time": When a scene is recalled, all the scene members
are dimmed from their current brightness value to the parametrized brightness value using flexible
dimming time which can be adjusted via the KNX. The value can be changed via the Flexible time for
dimming/fade time (...) group object.
For further information see Group object Flexible time for dimming.
Note
Flexible dimming time is received via the Output x Flexible time for dimming/fade time group object
and affects various output functions:
•
Dimming time for turn on/off value
•
Dimming time for brightness value
•
Dimming time for slave brightness value
•
Scene transition time
To use the Flexible dimming time function you first need to enable the output's Flexible time for
dimming/fade time group object in the A Output/Functions parameter window. You also need to
select the function for the parameter that can be changed via KNX. We recommend that you only
change one time via KNX. Otherwise the dimming time has to be rewritten on the ballast every time
a function is called, which impairs function performance.
Yes
No
Yes: After a download or KNX bus voltage recovery, the scene values for the scene members are
overwritten with the values set in ETS.
No: After a download or KNX bus voltage recovery, the scene values for the scene members are not
overwritten with the values set in ETS. If no scene values have been stored, the gateway sets them
to the maximum brightness.
