Deactivation of constant light control

Constant light control can be deactivated by users at any time if this option has been enabled.
Corresponding parameterization options can be found in the
page 107. The deactivation of 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 the light controller operates (controls), the lighting group in the
page 67, must be selected as the light controller 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 light controller 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 Function Activate controller. In the activated state, the light controller is started as
follows:
Constant light control is then started or set to the control state when the switched off lighting is switched on
(a telegram with the value 1 is sent via communication object Switch). Alternatively, a renewed telegram
with the value 1 can be sent to the communication object Function Activate 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.
