Features
» Automatic detection of the nature of the load: R+L, R+C and
LED. The use of ESL lamps requires manual setting of the na-
ture of the load using the knob on the face of the dimmer;
» Smooth brightening and dimming to extend the life of the con-
trolled lamp;
» Adjustable brightening and dimming rates;
» „Memory" of light intensity settings – after each switch-on,
the lighting returns to the previously set brightness. Not ap-
plicable to ESL lamps;
» Adjustment of the minimum illuminance level of the control-
led lamp (especially important for ESL lamps, requiring mini-
mum ignition and holding current);
» ON mode – switching of the lighting to maximum brightness
without dimming;
» Control input galvanically isolated from the dimmer supply
circuit.
Functioning
The lighting can be controlled by a number of pushbuttons con-
nected in parallel and located at different points in the room.
The receiver is switched on to the last set brightness level after
a current pulse caused by pressing any momentary (bell) button
connected to the relay. A short press of the button switches the
lighting on. Pressing and holding the button (for more than 1 se-
cond) changes the brightness level in one direction (brightening
or dimming). Each time the button is pressed again (for more
than 1 second), it adjusts in the opposite direction.
