Art. No. SC 1000 KNX
operation
only via switching object
the illumination.
Setting "only via display/button
operation": The display illumination is
switched on by any touch operation of
the display, sensor buttons , and or by
an optionally available push-button
extension module of the button or rocker
operation. The device switches off the
illumination of the display automatically
again as soon as the delay time defined
by the parameter "Automatic switch off
display illumination after" has elapsed.
Each new operation of the device via the
aforementioned events restarts the
delay time.
Setting "Only via switching object": In
this setting, the display illumination can
only be activated via the 1-bit
communication object "Backlighting On/
Off". The parameter "Behaviour of
display illumination switching object"
determines which telegram polarity
induces switching on or switching off.
Setting "via Display/button operation
and switching object": This setting is a
combination of the options "only via
display/button operation" and "only via
switching object". In this case, the
illumination can be activated either via
an operation on the device or via the
communication object "Backlighting On/
Off". The most recent event prevails and
specifies the status of the display
illumination.
If the display illumination is switched off,
the display can no longer be read.
Indicators and controls are then no
longer present.

This parameter defines the telegram
polarity of the object "Backlighting On/
Off". It also defines whether the
illumination remains on or off by a bus
telegram or whether the display
illumination switches itself again
automatically after switching on. In the
latter case, the time specified by the
parameter "Automatic switch-off of
display illumination" defines when the
automatic shut-off takes place
automatically after switching on by a bus
telegram. If no automatic switch off
should take place by the switching
object during activation of the display
illumination, the illumination stays on
until it is switched off again by the
object.
This parameter is only visible when the
display illumination can be activated by
the object.
