Allow switching off via rel. dimming
Options: no
yes
This parameter determines if switched on lighting can be switched off by a
Darker dimming telegram.
•
no: The brightness value stays at the lower dimming limit.
Dim period changeable via object
(Object: Dimming speed 0...100 %)
Options: no
yes
This parameter defines if the dimming speed (0...100 %) can be changed
via the KNX. The other dimming speeds, e.g. for Setting brightness or
Switch are not changed.
•
yes: The object Dimming speed 0...100 % appears. Using this object
the dimming speed for 0...100 % can be modified via the bus.
The 2 byte counter values (0...65,536) correspond to the time in
seconds which is required to dim from 0 to 255 (from 0 % to 100 %).
The dimming speed relates to the minimum dimming value. If the
dimming values are parameterised, the dimming range is still executed
with the same speed. This means, that the execution time from the
minimum dimming value to 100 % is shorter than the set dimming
speed.
Note
The value is overwritten by a download. With a bus voltage failure
the value of the change dimming speed via this object is lost, and at
bus voltage recovery the value is overwritten with the original value
parameterised in the ETS.
