4.3.2. With memory
With memory function, the rotary button operates as follows:
- Press briefly : off / on at previous dim level
Please note: The dimmer is never separated from the mains voltage. All components remain connected to the
power, even when the lamp is switched off.

4.4. Memory function

4.4.1. Switching the memory function on and off
The dimmer is supplied with the de memory function disabled. To activate the memory function, dim up to the
maximum light level and then hold the control button down for 10 sec. After 10 sec. the light dims from 100% to
a lower light level to indicate that the memory function has been switched on. After this change in light intensity,
immediately release the control button.
Repeat the procedure to deactivate the memory function.
This function, and the last set light level, is stored in a non-volatile memory; i.e. they will not be lost in the event
of a power failure. With the memory function activated, the dimmer will switch on for the first time at a light level
chosen by the manufacturer. Thereafter, the dimmer switches on at the last set value.
4.4.2. LED profiles LED 3, LED 7 and LED 8 with memory function
The dimming profile has been made in such a way, that the dimmer is shortly switched on at < 50 % of the
light intensity, before changing into the memory setting.

Action
Connect the device to the mains
voltage.
Replace the wire.
Place or replace the lamp.
Increase the minimum dimming level
or use a profile with boost function
(LED 3, LED 7 or LED 8).
Choose another profile and adjust the
minimum dimming level.
Check if the lamp is dimmable. This
is shown on the packaging by the
following symbol:
Check whether the load is too high.
When doing this, keep in mind the
reactive power of ferromagnetic
transformers.
Check the temperature in the flush-
mounting box (max. 35 °C).
Check whether mixed loads are being
used.
dimming profile is For LED lamps, use the profiles in the
following order of preference:
- DEFAULT 1
- LED 4, LED 5, LED 6
- LED 7 or LED 8 (with boost function)
Check if the lamp is dimmable. This
is shown on the packaging by the
following symbol:
Increase the minimum dimming level
or use a profile with boost function
(LED 3, LED 7 or LED 8).
Choose another profile and adjust the
minimum dimming level.
Place a PLC filter (Ripple Control
Rejector)
Replace the lamp if it flashes during
dimming the light up and down.
Replace the dimmer.
Place a 'bypass' or bleeder over the
lamp.
Select dimming profile Default 1, LED 4
or LED 8.
Select dimming profile LED 5 or LED
7 (note: the lamp might begin to flash
at maximum light intensity because
the lamp is highly capacitive). In
that case, we recommend placing a
different lamp.
Select dimming profile LED 3, LED
7 or LED 8.
