Art. No. SC 1000 KNX
4.2.4.1.15 Master button
The device has a master button on the touch sensor surface outside the display area
W
. The
master button can be linked to any existing KNX channel. In this way, a function, such as the
switching of room lighting, can be executed quickly and easily without touch operation of the
display pages.
The master button has a sensor surface (figure 52).
Figure 52: Sensor surface of the master button
A KNX channel can be configured as a rocker function (two button operation - the sensor
surfaces execute separate operating functions) or as a push button function (single-surface
operation - both sensor surfaces execute the same operating function). The master button
always executes push-button functions for channel functions that can be configured alternatively
to pushbutton or rocker functions (figure 53).

In the channel function" Venetian blind/shutter (position)" and the "Venetian blind" shading
method, the blind/shutter can be controlled exclusively by the master button. Slat control by
the master button is not possible.

A switched off display illumination disables operation and display elements of the display
(see chapter 4.2.4.1.17. Display illumination and operation LED). Consequently, these
elements are not operational if a display illumination is switched off. The master button,
which is located outside of the display, is independent of the display illumination and
disabling of display operating elements. Consequently, the master button can also be
operated with a dark display.
