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
Standard functions can be extended with an extra long keypress. For example, the blinds function: a short/
long keypress moves a single blind, an extra long keypress then moves all blinds in the living room (group)
centrally.
The innovative group control can also be used for lighting: the short keypress switches the individual
lighting , the long keypress switches all the lights in the room and the extra long keypress switches the
entire floor, for example.
Status LED / Orientation light (only Push-button Plus 55)
Next to the buttons are two-colour status LEDs which can react to internal objects, external objects or
button operation. The display behaviour can be set differently (red/green/off and permanently on or
flashing).
There is an additional LED in the centre which can be used as an orientation light.
Logic function (only Push-button Plus 55)
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.
Long Frame Support
The push-button supports “long frames” (longer telegrams). These contain more user data per telegram,
which signicantly reduces the programming time.
