2.2 Special functions
Button functions and levels
A function can be triggered by means of a pair of buttons or a single button, thus providing a wide
range of operating options. The functions can be distributed over up to 3 levels. The switching of the
levels is either fixed via the two upper sensor surfaces or via two hidden sensor surfaces on the lower
edge of the unit.
Mapping function
By means of a mapping function, configured button functions can be easily assigned to other sensor
surfaces. There is no need for time-consuming reprogramming.
RGB Status LEDs
Next to the sensor surfaces are RGB LEDs, which can react to internal or external objects and/or to
button actuation. The display behaviour can be set differently for "Day" and "Night" mode. The RGB
status can also be displayed during Standby. The flashing rhythm of several push-buttons is
synchronised by means of a master/slave object.
Logic functions
The push-button offers 4 (AND/OR) logic functions with which nested functions can also be realised.
Both internal and external input objects can be processed, the send condition and the output type
can be set.
Slap- and cleaning function
The slap function can take over frequent functions such as switching the main lighting on and off. All
it takes is a short, flat touch on the push-button (Slap!). Almost every single button function can be
set as a push-button function and used as an input of the integrated logic. To clean the Push-button
Smart, it can be switched to cleaning mode by touching it flat for a long time. After cleaning, the
cleaning function is automatically deactivated again.
Standby and status elements
In Standby, up to 6 status elements are displayed in up to 3 lines. These visualise any values of the
KNX bus. In addition to the date, the time can be displayed in 24 h or 12 h AM/PM format. Multimedia
information such as artist, title or running text can be output via 14-byte status texts. The standby
display can be deactivated via an object.
Message function
A total of 4-bit alarms are available to the user, which can display predefined messages. For
example, the opening of a window or a motion can be indicated. There is also a 14-byte message
object that can be used to display text messages sent via the bus.
Images downloadable via DCA App
Via a free DCA App, any images of the size 64x64 pixels can be reloaded and configured.
Long Frame Support
Support of sending longer telegrams and thus the integration of more user data per telegram. This
significantly shortens the programming time.
Updateable via DCA
With the help of the MDT Update Tool, the devices can be updated if necessary. The download is
available free of charge at www.mdt.de and www.knx.org.

2.5 Commissioning
After wiring the unit, the physical address is assigned, and the application is programmed:
(1) Connect the programming interface with the bus, e.g. with MDT USB Interface.
(2) Switch-on bus voltage.
(3) Activate programming mode by simultaneously touching/pressing buttons 7 and 8 on the unit
(status LEDs on the right and left of the button light up red alternately).
(4) Loading the physical address from the ETS software via the interface (red LED goes out as
soon as this has been successfully completed).
(5) Loading the application, with desired parameterization.
(6) If the device is enabled, you can test the requested functions (also possible by using the ETS-
Software).
2.6 Reload symbols
Any symbols can be reloaded into the Push-button. For this purpose, a DCA app "MDT Glass Push-
button II Smart/Push-button Smart 86" must be downloaded and installed once from the MDT
website or from the shop at my.knx.org. The images to be reloaded must fulfil the following
requirements:
•Format: Bitmap
•Size: 64x64 Pixels
•Colour: Black/White
•Using ETS5 or higher
