Deactivation of constant lighting control

Constant lighting control can be deactivated by users at any time if this option has been enabled.
Corresponding parameterization options can be found in
page 103. The deactivation of the light control can for example be implemented by a local operation,
dimming or switching of the lighting. Thus the user always has the option of setting their optimum
brightness.
4.9.3 Activating constant lighting control
Before lighting control operates (controls), the lighting group in
must be selected via the parameter Select additional function.
The light control is activated and controlled after the first download.
With a further download, the state of the lighting control is set to suit the parameterized setting. Light
control can be activated (telegram with value 1) or deactivated (telegram with value 0) via the
communication object Activate function controller. In the activated state, the light control is started as
follows:
Constant lighting control is then started or set to the control state when the switched off lighting is switched
on (via communication object Switch a telegram with the value 1 is sent). Alternatively, a renewed
telegram with the value 1 can be sent to the communication object Activate function controller to start
control.
The switch telegram can also be sent by a presence detector. Hereby, manual operation of the lighting is
totally unnecessary. This is useful to ensure optimum energy consumption. A special brightness level is
always available for certain tasks.
In the following cases, the light control, which is in standby mode, is not initiated by an ON telegram:

The output is blocked or is under forced operation.

The Follow-up time of the inactive control is active.
