Staircase lighting with Light control function

With the DALI Light Controller, there is a possibility of using the Staircase lighting function in conjunction
with the constant light control. This means constant light control is performed during the operation of the
Staircase lighting function. This combination is very efficient from an energy-efficiency point of view. In
addition to the limited switch-on duration of the lighting, it is only controlled with the brightness value that is
actually necessary to light up the room to a sufficient level.
Control is only used during the operation of the Staircase lighting function. During the dimming-up,
dimming-down and during the basic brightness run time, light control is suspended and is in standby.
During switching on or retriggering of the staircase lighting, the lighting is switched on at the switch-on
brightness of the Staircase lighting function.
Should the Staircase lighting function be deactivated, the lighting group has a "normal" control function. In
the same way, the lighting group with the deactivated Light control function behaves like a lighting group
with the Staircase lighting function. If both functions are deactivated, the lighting group is a "normal"
lighting group.
If the light controller is inactive and is activated via the communication object Function Activate controller,
the Light control function initially goes to standby. The staircase lighting is not restarted or retriggered in
this case. Only after the next switch-on via the communication object Switch will the light controller start to
control during the staircase lighting time. A prerequisite for this is that the staircase lighting time has been
ended and the Staircase lighting function is in the dimming time, basic brightness run time or subsequently
in standby.
The Staircase lighting function has a higher priority than the additional function Light control with regard to
the parameterized reaction to incoming KNX telegrams. The reaction should be defined in the parameter
window - Gx Staircase lighting.
