Basis brightness hold time
1 s, 2 s, ...10 s, 12 s, 15 s, 20 s, 30 s, 45 s, 50 s,
Options:
1 min, 2 min... 5 min...10 min...50 min,
1 h, 2 h...24 h,
No limitation

1 s...24 h: This is the time duration, in which the basis brightness is switched on.

no limitation: basis brightness is not switched off automatically. The brightness value is
changed only if a new telegram is received via the KNX or by forced operation, e.g. with a fault
where the brightness value is changed.
Note
The function Staircase lighting is recalled by an ON telegram of the lighting group if the
additional function Staircase lighting is selected for this lighting group. This parameterization is
undertaken in the Parameter window Gx
telegrams (brightness value, relative dimming, scene recall) and voltage recovers can also be
parameterized there.
The reaction to a switch telegram is not explicitly programmable and responds as follows:
The function Staircase lighting is triggered by an ON telegram with the value 1 to the
communication object Switch of a lighting group. With an OFF telegram, the lighting group is
controlled with the basis brightness of the function Staircase lighting. The function Staircase
lighting remains in standby mode and is started by a renewed ON telegram. Should the lighting
group receive a renewed ON telegram during ongoing function Staircase lighting, the function
Staircase lighting is restarted (retriggered).
The function Staircase lighting is also started if the lighting group receives an ON telegram with
the value 1 on the communication object Activate staircase mode or Activate staircase
function/status.
