Parameter window - Gx Control Operating

Control Operating is enabled if in parameter window
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 control 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 control. The light control is in standby mode and recommences with light control via an ON
telegram or when a telegram with the value 1 is again received on the communication object Activate
function controller.
Brightness value when lighting control
is activated
Options:
Using this parameter, the brightness value that is set immediately after activation of the light control can be
defined. Commencing at this value the lighting is gradually controlled up to the setpoint.

previous brightness value: The last brightness value is the constant brightness value which existed
when light control was switched off. If no previous brightness value is stored, 100 % or maximum
brightness is assumed.

Brightness value (calibration lighting): Brightness value that has been set during artificial lighting
calibration to set the setpoint brightness. As this value is the current constant lighting control operating
point, the current brightness value required should not deviate greatly from it. Thus the control very
quickly achieves the setpoint brightness without needing to undertake control steps.
