Technical Manual Glass Push Button II Smart BE-GT2xx.01
Logic functions
By means of a total of 4 logic functions it is also possible to realize interleaved function calls, e.g. to
release a scene call only in day mode. The logic function can process both internal and external states.
"lap fun tion
The "Slap" function, which is triggered by the simultaneous touching of 3 or more keys, allows
intuitive operation. By this function, e.g. the light can be switched on when entering the room
without the operator having to search for the exact position of the individual keys.
Info-Display
In standby mode up to 4 status elements can be displayed. These status elements can visualize any
values of the KNX bus as well as the time or 14 byte status texts.
Message function
A total of 4 1-bit alarms are available, which can display predefined messages. For example, the
opening of a window or a motion can be reported. There is also a 14 byte message object which can
display text messages sent via the bus.
Long Frame Support
Supports the transmission of longer telegrams and thus of more user data per telegram. This
significantly shortens the programming time (as of ETS5).
Requirement: The use of a programming interface which supports the transmission of long frames,
e.g. MDT SCN-USBR.01 or SCN-IP000.02/SCN-IP100.02.
2.2 Usage & Possible Applications
The buttons have all the functions of a modern KNX switch and are designed for flush mounting. By
means of a keystroke, the pushbutton can carry out parameterized functions, e.g. scenes or dimming.
All models have a large color display and 6 buttons, which are equipped with RGB LEDs. For each
function specific symbols and colors can be parameterized. All buttons can be parameterized as 4-/6-
/8- or 12-fold push button. The selection of the functions 7 to 12 is controlled via levels. Furthermore,
the buttons have a brightness sensor with which the button can dynamically adapt to the ambient
brightness. 4 logic blocks, a cleaning function and a "Slap function" complete the performance
spectrum of the push buttons.
The pushbuttons of the BE-GT2T version also have an integrated temperature sensor, which can be
used for room temperature detection. The BE-GT2T version has additional functions for controlling
the integrated controller of the MDT heating actuator.
