RGB State LEDs
An RGB status LED is available to the user for each function. This can visualize both, a keystroke as
well as an external or internal status with any color.
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.
“Slap” function
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
Support of sending longer telegrams and thus the integration 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 push buttons of the series BE-GT2T/BE-TAS86T version also have an integrated temperature
sensor which can be used for room temperature detection.
The BE-GT2T/BE-TAS86T series has further functionalities for controlling the integrated controller of
the MDT heating actuator.
