2.1.1 Special functions of the Glass Push Button II Smart & Push Button Smart 86
The Glass Push Button II Smart and the Push Button Smart 86 provide a very extensive application
with the following special functions:
Large RGB color display for visualization
Large, active color display for function- and status indication can be freely parameterized by the user.
The symbols and colors are freely selectable!
Symbols can be reloaded via DCA App
A free DCA app can be used to reload and parameterize any image of the size 64x64 pixels!
Can be used as a 4/6/8/12-button
Up to 3 levels with up to 4 functions per level can be activated. Thus, the button can control up to 12
functions. The levels as well as the functions can be named individually. The levels can be selected
using the upper two keys, the hidden sensor keys or a scene.
Extensive application
The function range of the application exceeds that of a "normal" push button by a multiple. In
addition to the usual functions such as blinds, switching, dimming, scene, the user is also provided
with functions for controlling the HSV color circle or a function for controlling the color temperature
(Tunable White). The button contains special symbols to control and visualize these functions!

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.

2.5 Settings at the ETS-Software
Selection in the product database
Manufacturer: MDT Technologies
Product family: Glass Push Button II Smart
Medium type: Twisted Pair (TP)
Product name: addicted to the used type, e.g.: GT2TW.01
Order number: addicted to the used type, e.g.: GT2TW.01
2.6 Commissioning
After wiring the device, the assignment of the physical address and the programming of the
application follow:
(1) Connect the interface with the bus, e.g. MDT USB Interface
(2) Set bus power up
(3) Activate the programming mode by pressing buttons 7 and 8 on the device simultaneously,
(Status LEDs on the right and left side of the button alternately flash red)
(4) Loading of the physical address out of the ETS-Software by using the interface (Red LEDs will
turn off as soon as this is successfully completed)
(5) Loading of the application, with requested parameterization
(6) If the device is enabled you can test the requested functions (also possible by using the ETS-
Software)
2.7 Reload Symbols
Any symbols can be loaded into the device. To do this, a DCA app "MDT Glass Push Button II Smart"
has to be downloaded and installed from the MDT website or the my.knx.org shop. The images to be
uploaded must meet the following requirements:
Format: Bitmap
Size: 64x64 Pixel
Color: Black/White
Usage: ETS5 or higher

Table 5: Communication objects –Default settings: Common objects
The preset default settings can be taken from the tables above. The priority of the individual
communication objects as well as the flags can be adapted as required by the user. The flags assign
the respective task to the communication objects in the programming. C stands for communication,
R for reading, W for writing, T for transmission, and U for updating.

4.2.2.2 Adaption to ambience
The following settings can be used to influence the adaptation of the display to the ambience
(Here: Glass Push Button II Smart):

A proximity sensor is only integrated on the Push Button Smart 86.
This was always present and can also be deactivated from hardware revision R2.4.

Table 8: Settings –Adaption to ambience
Principle of brightness adjustment:
The Glass Push-Button II Smart/Smart 86 has an internal brightness sensor and can dynamically
adjust the display brightness to the surroundings. The "brightness" parameter influences dimming
behaviour and the threshold at which the display is dimmed. The parameter for minimum brightness
defines the absolute lowest threshold up to which the display is dimmed.
In the programmed state, the menu for the brightness adjustment can be called up by pressing the
sensor surfaces 7 and 8 simultaneously:
In this menu the end user has the possibility to adjust the brightness settings independently (without
ETS). The settings are stored permanently in the device until the next transfer of the database.

If the parameter „Adapt display brightness to ambience“is set to “Yes”, the following adjustments
are available:
Brightness: Defines the basic brightness of the display and influences the dimming behavior of the
display according to the measured value for the ambient brightness.
min. Brightness: Defines the minimum brightness at darkness. In day mode, the adjustment for the
day mode is set and in night mode the adjustments for the night mode is set.
If the parameter „Adapt display brightness to ambience“is set to “No”, the following adjustments
are available:
Brightness: Defines the absolute, fixed brightness. In day mode, the adjustment for the day mode is
set and in night mode the adjustments for the night mode is set.
In addition, the brightness of the buttons can also be controlled via the bus. A push-button can be
either set as master and send its brightness value to the bus.
The push-buttons in slave mode then receive the time and adjust their display brightness accordingly.
Control via another KNX device is also possible.
