  •  Wall-mounted controllers with upstroke control WSB3-40 and WSB3-40H are the basic and most popular features (control) of the iNELS system.
  •  Built-in micro-switch with low upstroke offers elegant and pleasant control.
  •  Controllers WSB3-40 and WSB3-40H are supplied with 4-channels.
  •  Two-colored indication LEDs located in each controller can signal the status of controlled appliances or the status of any sensor or actuator in the system.
  •  Wall buttons in WSB3 series are compatible with both types of frames LOGUS90 (85.6x85.6 or 94x94 mm), therefore you can combine them with double and triple frames and classic products of the series.
  •  Each controller is equipped with a temperature sensor. It is also equipped with two analog/digital inputs (AIN/DIN), which can be used to connect two potentialless contacts or one external temperature sensor TC/TZ (e.g. for measuring floor temperature).
  •  Compared to standard wall buttons WSB3-20 and WSB3-20H are more flexible and multifunctional. You can, for example, control appliances with a short and long push of the button     (e.g.: dimming, shutter control, scenes).
  • Wall button WSB3-40H is comparable to the WSB3-40 but additionally equipped with a relative humidity meter
  •  Each button can control any appliance in the system and can use a variety of centralized or time-controlled features. Accordingly, the customer can choose the simplicity/complexity of the operation. The big advantage is the possibility to change the method of control by only making software modifications without physical interventions into the structure of the building.
  •  Each button (fold) can have different functional modes besides lighting control:
    a) Classic wall-switch - upper button ON, bottom button OFF
    b) Button controller (impulse relay) - first press ON, second press OFF
    c) Dimmer - short press – ON/OFF
    d) Time switch - ON after press, automatically OFF after set time
    e) Setting light scenes – for example: for watching TV:
         - shutters down
         - main light 30% intensity
         - wall-lamps 50% intensity
