Operation
The universal dimmer can be operated
as follows:
1.) locally from the device itself
2.) through radio-control telegrams or
3.) from an extension unit (cf.
„Installation of an extension unit).
1.) Local operation
The universal dimmer can be switched
alternately on and off by brief depressions
(approx. 1 second) of the programming
key.
2.) Operation with radio-control
transmitter
Depending on how a programmed radio-
control transmitter (e.g. hand-held trans-
mitter) is operated, the lighting is either
switched on or off (short depression of
key) or dimmed (long depression of key).
After reception of a data telegram from a
programmed radio-control detector, the
universal dimmer is switched on for about
1 minute with the preset memory
brightness.
After reception of a data telegram from a
programmed presence detector or light
sensor, the universal dimmer performs
light control functions. For more informa-
tion, refer to the operating instructions of
the radio presence detector or light
sensor.
3.) Operation from extension unit
The universal dimmer can also be
switched and dimmed from an extension
unit (see „Fitting - extension units").
The extension unit can be operated by
short and long depressions of the
pushbutton:
The extension unit has an upper and a
lower pushbutton rocker.
Short depression (< 0,4 s)
The lighting is switched on (or on with
memory value brightness) or off.
Long depression (≥ ≥ ≥ ≥ ≥ 0,4 s)
The brightness of the lighting is increased
with a long push on the button (upper
rocker) or reduced (lower rocker.
Memory function
The selected brightness can be stored
in the universal dimmer as memory
brightness. This memory brightness is
then recalled as starting brightness when
the dimmer is switched on.
Storing the memory brightness value
1. Select the desired brightness of the
lighting.
2. Depress the programming key for at
least 4 seconds. This is confirmed by
a soft-start, i.e. the lighting is shut off
briefly and then increased in brightness
up to the stored memory value.
Important
• The memory function is not available
if a presence detector or light sensor
has been programmed.
• In as-delivered condition and after a
mains failure, the memory value is set
to maximum brightness.
