Switch-off delay after detection of presence: After this time elapses, the controller is switched off and either the
orientation light value is output or the dimmer is switched off.
Control value at start of control: The control is started with output of this value if the last received light value
was below the current set value; otherwise, it starts with output of the value 0 %.
Maximum step of control value: The step size of the control value from the controller cannot exceed this value.
Minimal control value: If the calculated control values for the control are below this limit, 0 % is sent to switch off
the dimmer.
Orientation light after download: After the system is started up or the gateway is programmed via ETS, this value
is output at the beginning of the orientation light phase if no new value was received yet via the "Orientation
light value" communication object.
Duration of orientation light: In the orientation light phase, the dimmer is switched off after this time elapses by
sending the value 0 %.
Switch-on level for the light: If the lighting drops below this light value during control or in the orientation light
phase, the valid orientation light phase in each case or the current control value of the control is output;
otherwise, 0 % is output.
Wait for switch-off telegram to start switch-off delay : When set to "No", the switch-off delay is restarted with
every ON telegram of the detector. When set to "Yes", the switch-off delay is started with the first OFF telegram of
the detector if the control is active.
Light controller, on/off
This controller type is available for light control. An upper and lower threshold value at which the controller should
switch can be entered. Presence and manual override can be handled as well.
Communication objects
The devices printed in italics are typical application examples of these objects.
Input objects:
Input lux:
From a light sensor;
current value of control
Input presence:
From a presence detector;
for evaluating presence
Input switch on/off manually:
From a key;
the controller can be manually overridden for an adjustable period
Output object:
Output switch on/off:
To an actuator;
switch output of on/off controller

Parameters
Operating mode: This parameter can be used to define how the controller operates:
Switch automatically only by values:
Only telegrams to the value object and manual switching are
evaluated by the controller.
Switch on only manually, switch off automatically:
The channel can only be switched on manually. It is
switched off when the input value exceeds the switch-off threshold or there is no presence. This is a
semiautomatic operating mode with automatic switch-off. It prevents light in an office from being left on
accidentally, for example.
Switch automatically by values and presence:
Telegrams to the value object, to the presence object and
manual switching are evaluated by the controller.
Switch-on telegram when going below a value: See the description of the next parameter.
