This group object is enabled if the additional function Slave is enabled in X Slave template (group x/ballast x) parameter
window, p. 112 and simultaneously, the Source (slave is controlled via) parameter is set to Object "slave brightness value" in
the A Output, Group x/Ballast x slave parameter window.
The Slave (group or ballast) receives the brightness value via this group object, e.g. from a higher-level light controller acting
as the master.
If the Slave function is not active or is latent (standby) after an OFF telegram with the value 0 on the Switch or Status switch
group object, telegrams on the Brightness value of slave group object have no effect.
In the A Output, Group x/Ballast x slave parameter window you can define whether a Switch, Brightness value, Relative
dimming or Scenes telegram interrupts the Slave function.
Brightness values above or below the predefined maximum brightness/minimal dimming values (dimming thresholds) are not
set; the dimming thresholds are set instead.
