The upper-and lower dimming takes place by capacitive contact-free sensors, in which the position of sensor surface and light is determined by finger. Totally 15 brightness level and out are available, which are not necessarily navigated along the "slider-way" by finger; but certainly selection of the favourite brightness spot is possible directly by the tip. the last position of finger is carried as FS20-command for Dimmer The FS20-Dimmer-Slider is set very flexibly, as the sender unit is provided for the installation in Standard-UP-switch and by the help of adapter frames (refer Internet-offer), the adaptation to the respective switching programme can take place in house. The programming of FS20-command can follow separately on two canals so that two independent illuminated scenes are controlled. The programming can take place by integrated IR- receiver diode and can also follow via FS20 IRP (64 63 95). By three covers with delivery (each 1 x in black and in white is pressed, 1 x transparent, no-pressure for individual designing ), and flexible, optical adaptation to ambient is also possible. Delivery without 50-mm-Adapter frames
