Note
The light control can assume three operating states:
Control is not active: The light control has been deactivated via its object
activate control (telegram has been received with value 0). In this state
the Light Controller acts like a normal Switch/Dim actuator. ON commands
do not cause the light control to start. Only after a telegram with the value
1 has been received on the object activate control is it possible to start the
light control. Please observe that after the telegram with the value 1 has
been received the light control will start to control. An output of the Light
Controller can only assume one of the three additional functions Light
control, Staircase light or Slave mode. If this additional function is active,
it is displayed via the first bit of the object Status byte.
Control is in standby mode: The light control is active but has however
been ended, e.g. by the OFF command. The light control still remains
active in the background and starts again with control after an ON
command.
Control controls: The Light controller controls and adjusts the lighting so
that the setpoint brightness is set. The status indicating if the light control
operates is displayed via the Status function object.
If lighting control is active: reaction on ...
With these three parameters you can set how an output of the Light
Controller reacts with active lighting control if the following telegrams have
been received:
