Note
An OFF command (telegram with the value 0) to the object Switch or
Switch/Status always causes a switch off of the lighting and the light
control. The light control is in standby mode and recommences with light
control via an ON command (telegram with the value 1) received on
the object Switch or Switch/Status or activate control.
Relative dimming
Options: no reaction
deactivate lighting control
setpoint = new sensor value (temporary)
•
no reaction: A dimming command to the object relative dimming has no
effect on the lighting and the lighting control.
•
deactivate lighting control: With a dimming command via the object
relative dimming the lighting control can be interrupted.
The light control can be reactivated by an ON telegram or via the object
activate control.
•
setpoint = new sensor value (temporary): The new sensor value (current
brightness) is accepted as a temporary setpoint. After a brief interruption
– until the temporary setpoint is accepted – the light control will continue
with the new setpoint. The old setpoint is restored at the next activation
of the light control, e.g. switch on via object Switch or via the object
activate control.
Brightness value or preset or scene recall
Options: no reaction
deactivate lighting control
•
deactivate lighting control: The light control can be interrupted by a
brightness command, a scene recall or by a preset command.
The lighting control switches to the standby mode.
The received brightness value command is implemented. The light
control can be reactivated by an ON telegram or via the object Switch.
•
no reaction: A brightness command, a scene recall or a preset command
has no effect on the lighting and the lighting control..
Brightness value when lighting control is activated
Options: 100 % (255)
last brightness value
99 % (252)/...70 % ( 179)/2 % (5)/1 % (3)
Using this parameter the brightness value which 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.
The last brightness value is the constant brightness value which existed
when light control was switched off. If no last brightness value is stored,
a 100 % or maximum brightness is assumed.
