Glass Push Button II Lite [BE-GTLxxx.x1]

2.2 Functions

Extensive button functions
A function can be triggered by a single button or a pair of buttons. This provides a wide range of operating
options. The button functions include "switch", "send values", "scene", "switch/send values short/long
(with 2 objects)", " blinds/shutter" and "dimming".
Innovative group control
With the innovative group control, standard functions can be enhanced by pressing the button extra long.
For example, the blind function in a living room. A single blind is operated with the normal short/long key
press. With the additional extra long key press, for example, all blinds in the living room (group) are
operated centrally. The innovative group control can also be used for lighting. A short button press
switches a single light on or off, a long button press switches on or off, for example, every light in the room,
and an extra long button press switches on or off, for example, every light on the entire floor.
Multitouch-function
With the multitouch-function, up to 4 different functions can be programmed on a single button. A
separate datapoint type is available for each function, which means that different functions can also be
triggered.
RGBW State LEDs
One RGBW status LED is available for each button. The status LED reacts to key presses or external/
internal objects. The colours red, green, yellow, blue, pink, cyan and white can be assigned. A separate LED
is available for the colour white to provide a clear, high-quality white. Various colours and brightness levels
can be assigned using a day/night object. A priority object offers the option of visualising important states
via LED.
Integrated temperature sensor (Only BE-GTLxTx.x1)
The integrated temperature sensor can be used for room temperature control. The measured temperature
value of the sensor is sent to the integrated temperature controller of the MDT heating actuator. This
eliminates the need for an additional temperature sensor in the room. The sending conditions of the
temperature value are adjustable. An upper and lower threshold value are available for limit monitoring.
Slap function
The slap function, which is triggered by touching the entire surface of the button, allows intuitive
operation. This function can be used, for example, to switch on the light when entering the room without
the user having to search for the exact position of the single buttons.
Logic functions
A variety of function calls can be realised through a total of 4 logic blocks. The logic function can process
both internal and external objects.. The logic function can process both internal and external status
information.
Updateable via DCA
If necessary, the device can be updated using the MDT update tool (DCA).
The download is available free of charge at www.mdt.de and www.knx.org.
Long Frame Support
The device supports "long frames" (longer telegrams). These contain more user data per telegram, which
significantly reduces the programming time.
