Adjusting the minimum brightness for the
rotary dimmer
The minimum brightness level can be adjusted to
prevent poor switch-on behaviour or flickering of
the load in the lower dimming range.
Switch off load.
Press and hold rotary knob for approx 10
seconds.
The load will flash once after 3 seconds and
then flash a second time after 10 seconds.
Release the rotary knob.
The device is in fine adjustment mode for the
minimum brightness level and the lamp is
switched on at the minimum brightness level.
Depending on the lamp, the minimum bright-
ness level of the lights installed may be too
low and the lights may appear off, gradually
increase the brightness level by rotating the
knob clockwise.
