Possibility to assign a name (max. 15 characters) and a reaction time (65ms, 1s, 2s of 3s) which can be
saved in the non-volatile memory.
The command labels are displayed on the LCD. These labels consist of 2 lines of 16 characters each and
will also be saved in the non-volatile memory.
When pressing, maintaining pressed and releasing a push button, an instruction is being sent.
Instructions will be accepted when setting the backlight, switching the indication LEDs on and off, slow,
fast or very fast blinking of the indication LEDs, calling up the module type, the push button names and
when reading from or writing to the non-volatile memory.
The module can respond with the module type, the push button name or the contents from the memory.

Connection
For connection between the modules, use twisted pair cable (ex. EIB 2x2x0.8mm2, UTP 8x0.51mm- CAT5
or other). Use minimum 0.5mm² cable. For long wiring (>50m) or if a lot of modules ( > 10) are connected
to one wire, use 1mm² cable. Connect the 12-18Vdc (mind the polarity) and connect the bus wires (mind the
polarity).

Termination:
If the module is connected at the start or end of a cable on the VELBUS, place the ‘TERM’ jumper.
Remove the jumper in all other cases.
If different cable wiring topologies (tree, star, loop, ...) are used, place a jumper on the end module of the
longest cable only, NOT on each end point.

Use
The module consists of 4 push buttons with corresponding LED indication and one configuration push
button. The label for each push button is displayed on the LCD.
This module allows defining up to 8 commands.
The module will display the first 4 commands by default:
Push the configuration button to switch to the next four commands:
The module switches back to the default command display after 15 seconds of inactivity.
You can switch between the two displays at any time by pressing the configuration button.
When pressing, maintaining pressed and releasing a push button, an instruction is being sent on the
Velbus®. These messages identify which push button has been pressed, maintained pressed or released.
Other modules (relay modules, blind control modules, dimmers...) connected to the Velbus® will react and
answer by resending a command message to the push button module. This command will switch off, light
of blink the indication LEDs.
How a specific push button will control a particular module is explained in the learning mode of the
concerning modules.
