Parameter window - Gx Control Operating

The parameter window - Gx Control Operating is enabled if, in the
the parameter Additional function is selected with the option Light control.
In this parameter window, the response of the light controller to the switch, dim, brightness or scene
telegram is defined.
The light controller is activated by an ON telegram (receipt of a telegram with the value 1 on the
communication object Switch or Switch/Status). An OFF telegram always causes switch off of the lighting
and the light controller. The light controller is in standby mode and can recommence light control via an
ON telegram or when a telegram with the value 1 is again received on the communication object Function
Activate controller.
Brightness value when light control
is activated
Options:
Using this parameter, the brightness value which is set immediately after activation of the light controller
can be defined. Commencing with this value, the lighting is gradually controlled up to the setpoint.

Last brightness value: This is the last constant brightness value that existed when the light controller
was switched off. If no previous brightness value is stored, 100 % or maximum brightness is assumed.

Brightness value (calibration lighting): The brightness value that was set during artificial light
calibration to set the setpoint brightness. As this value is the current constant light control operating
point, the current brightness value required should not deviate greatly from it. Thus, the controller very
quickly achieves the setpoint brightness without needing to undertake control steps.
