Description KNX Push-button

The MDT Taster triggers KNX/EIB telegrams after a button press, depending on the parameterization. The buttons can be parameterized as button pairs (two-rocker) or as single buttons. In addition to dimmer/blinds, contact type, and block communication objects, numerous functions are available. The MDT Taster Plus features 4 integrated logic modules. Sending a second object is possible via the logic modules. The central labeling field with a cover foil allows for individual labeling of the push-button. The labeling template can be found on the MDT website in the download area. MDT Taster Plus series additionally features an orientation light and a bicoloured (red/green) LED per rocker. These can be controlled with internal or external objects. It is possible to display 3 states with one LED, e.g., LED off = 'absent', LED green = 'present', LED red = 'window open'.

The MDT Taster Plus TS 55 has an additional temperature sensor for detecting the room temperature.

Fits 55mm systems/ranges:
