DESCRIPTION
LED illumination is getting more popular. By dimming the output of the LED strips (12V or 24V series) an
attractive atmosphere can be created. A dimmer module is placed between the external LED power supply and
the LED strip.
The use of Pulse Width Modulation (PWM) greatly reduces heat development inside the dimmer module
compared to linear regulators.

Depending on the setting of the ‘MODE’ rotary switch the dimmer module will act as follows:
MODE Operating mode Description
0 Start/stop timer Pushing the pushbutton will switch on the LED strip. When
the set time (see ‘TIME’ switch) expires the LED strip is
switched off.
Pushing the pushbutton while the LED strip is already on
will switch it off immediately.
1 Staircase lighting timer Pushing the pushbutton will switch on the LED strip. When
the set time (see ‘TIME’ switch) expires the LED strip
brightness will slowly diminish to be completely off after 30
seconds.
Pushing the pushbutton while the LED strip is already on
will restart the timer.
Dimmer A short push will switch on the LED strip (full brightness).
2
Another short push when the LED strip is already on will
switch it off.
Push and hold will dim the LED strip up to maximum or
down to minimum brightness. The next push will dim in the
opposite direction When the set time (see ‘TIME’ switch)
expires the LED strip is switched off.
3 Dimmer with memory function A short push will switch on the LED strip (brightness as
memorized since last use). Another short push when the
LED strip is already on will switch it off.
Push and hold will dim the LED strip up to maximum or
down to minimum brightness. The next push will dim in the
opposite direction.
When the set time (see ‘TIME’ switch) expires the LED strip
is switched off.
4 Multiple position dimmer Pushing the pushbutton will switch on the LED strip (full
brightness). Every next push within 5 seconds after the
previous will change brightness by 25%.
When the LED strip is on and the previous push occurred
more than 5 seconds earlier, a push will switch off the LED
strip.
When the set time (see ‘TIME’ switch) expires the LED strip
is switched off.
5 Slowly on dimmer Pushing the pushbutton will slowly turn on the LED strip to
full brightness. The duration to achieve maximum
brightness is determined by the ‘TIME’ switch.
Pushing the pushbutton while the LED strip is already on
will switch it off immediately.
6 Slowly off dimmer Pushing the pushbutton will switch on the LED strip to full
brightness.
Pushing the pushbutton when the LED strip is on will slowly
decrease brightness until the LED strip is off. The duration
to switch the LED strip to off is determined by the ‘TIME’
switch.
Pushing the pushbutton during decreasing brightness will
turn the LED strip back to full brightness.
7 Slowly on/off dimmer Pushing the pushbutton will slowly turn on the LED strip to
full brightness.
Pushing the pushbutton when the LED strip is on will slowly
decrease brightness until the LED strip is off.
The duration to achieve maximum brightness or to switch
the LED strip off is determined by the ‘TIME’ switch.
Remarks:
When the ‘TIME’ rotary switch is set to ‘0’ the dimmer module will always work in instant control, no matter what
operating mode is set. On other words, the LED strip will light up as soon as the pushbutton is pushed.
When the ‘TIME’ rotary switch is set to ‘F’ the dimmer module will not automatically switch off or the dimming speed
will be maximal when the module is set to slowly on, slowly off or slowly on/off mode.

USE WITH A VELBUS SYSTEM
The dimmer module can be part of a Velbus system and controlled by a control panel (VMB4PD) or using
pushbuttons connected to a pushbutton interface (VMB8PB).
To interconnect the Velbus modules the use of twisted-pair cable (EIB 2x2x0.8mm2, UTP 8x0.51mm - CAT5 or
equivalent) is recommended.
When a lot of modules (more than 10) are connected to the cable or longer cable lengths (more than 50m) are
used, it is important to use a cable with appropriate diameter (0.5mm² or higher).
Connect the bus to the module (beware of the polarity).
Connect the 12V to 18V direct current to the module (beware of the polarity).
A 12 or 24V direct current power supply is required for the LED strips. That power supply is completely separated
from the Velbus power supply. When connecting, make sure to use the correct polarity, as using the wrong
polarity will melt the internal fuse. The fuse can be replaced by removing the plastic power supply terminal guard.
Wiring diagram for 12V LED strips
Use a 12V direct current power supply for the LED strips.

It is also possible to use the Velbus in combination with pushbuttons that are directly connected to the pushbutton
input of the dimmer module.
The function of the directly connected pushbuttons is set via the ‘Mode’ and ‘Time’ rotary switches.

Addressing
Every module in the Velbus system must have a unique address.
On modules with a rotary switch like this dimmer the address is set using the ‘ADDR’ rotary switch (also refer to
the manual of the relevant module). For modules without rotary switches e.g. control panel VMB4PD or
temperature controller VMB1TC the address is set via a menu (see manual of the VMB4PD or VMB1TC).
These addresses may not be altered afterwards.
Remove the cover.
Select a unique address from ‘01’ to ‘FE’ for the dimmer module using the ‘ADDR’ rotary switches, except
addresses ‘81’, ‘91’, ‘A1’, 'B1', ‘C1’, ‘D1’, ‘E1’, ‘F1’ and ‘FF’.
In the example below, the address is set to ‘12’.
ADDR = 12
VMB1LED PWM LED strip dimmer Manual– edition 1_rev.2

Terminator
Terminator
Normally only 2 ‘TERM’ terminators must be used in a complete Velbus installation. Usually this will be on one
module inside the distribution box and on the module which is physically located furthest from the distribution box.
On all other modules, the terminator must be removed.
Remark:
In case the wiring contains a lot of branches, still only one terminator is placed on one module inside the
distribution box and one on the module which is physically located furthest from the distribution box. When
communication errors occur, an additional terminator can be used at the end of another branch. However, the
number of terminators should be limited as more terminators place a heavy load on the bus.
VMB1LED PWM LED strip dimmer Manual– edition 1_rev.2

Operation
The dimmer module can be operated in different ways:
• using pushbuttons directly connected to the pushbutton input:
o that activates the mode as set by the rotary switches (see ‘Use without Velbus’).
• using pushbuttons connected to a Velbus via a pushbutton interface VMB8PB or control panel VMB4PD:
o to switch on the LED strip (full brightness).
o to switch off the LED strip.
o to switch on (full brightness) or switch off the LED strip.
o to activate the mode as set by the rotary switches. Only for this pushbutton operation the mode and time
settings will be applicable to the dimmer module (see operating mode).
o to increase brightness of the LED strip.
A short push will light up the LED strip to full brightness (or to the last used brightness in case of a
dimmer wit memory function).
A long push will gradually increase the LED strip brightness until de pushbutton is released (or
maximum brightness reached).
o to decrease brightness of the LED strip.
A short push will switch off the LED strip immediately.
A long push will gradually decrease the LED strip brightness until de pushbutton is released (or
LED strip is off).
o to light op the LED strip at a certain brightness (atmosphere).
o by slider controls that light up the LED strip to the desired brightness.
The easiest way to assign an operating function to pushbuttons that are connected via a pushbutton interface or
control panel to the Velbus is by using the Velbus link software.
Up to 12 different pushbuttons can be assigned to each operating function.
However, functions can be assigned without using a computer.
Remember the address of the dimmer module to reinstate it later on.
Set the address of the dimmer module to the function for which pushbuttons will be assigned.

Repeat the previous step in case other pushbuttons on the Velbus system must be linked to an atmosphere.
Remark:
• In case the indication LED of the pushbutton that you would like to link to an atmosphere is not flashing, the
maximum number of atmosphere pushbuttons is reached.
• Unlinking a pushbutton is done by pressing and holding the pushbutton until its indication LED switches off.

Next step is to assign brightness levels to those atmosphere pushbuttons. Set the address of the dimmer module
A
to ‘81’. The MODE LED on the dimmer module and the indication LED(s) of the already linked atmosphere
pushbutton(s) will flash (fast). This way it can easily be determined which pushbuttons already have an
atmosphere function assigned.

Setting the operating mode
The function of the directly connected pushbuttons or linked ‘DIM’ Velbus pushbuttons is determined by the
position of the ‘Mode’ and ‘Time’ rotary switches.

Depending on the setting of the ‘MODE’ rotary switch the directly connected pushbuttons or the learned ‘DIM’
Velbus pushbuttons will activate following function:
MODE Operating mode Description
0 Start/stop timer Pushing the pushbutton will switch on the LED strip. When the
set time (see ‘TIME’ switch) expires the LED strip is switched
off.
Pushing the pushbutton while the LED strip is already on will
switch it off immediately.
1 Staircase lighting timer Pushing the pushbutton will switch on the LED strip. When the
set time (see ‘TIME’ switch) expires the LED strip brightness
will slowly diminish to be completely off after 30 seconds.
Pushing the pushbutton while the LED strip is already on will
restart the timer.
2
Dimmer A short push will switch on the LED strip (full brightness).
Another short push when the LED strip is already on will switch
it off.
Push and hold will dim the LED strip up to maximum or down
to minimum brightness. The next push will dim in the opposite
direction When the set time (see ‘TIME’ switch) expires the
LED strip is switched off.
3 Dimmer with memory function A short push will switch on the LED strip (brightness as
memorized since last use). Another short push when the LED
strip is already on will switch it off.
Push and hold will dim the LED strip up to maximum or down
to minimum brightness. The next push will dim in the opposite
direction.
When the set time (see ‘TIME’ switch) expires the LED strip is
switched off.
4 Multiple position dimmer Pushing the pushbutton will switch on the LED strip (full
brightness). Every next push within 5 seconds after the
previous will change brightness by 25%.
When the LED strip is on and the previous push occurred more
than 5 seconds earlier, a push will switch off the LED strip.
When the set time (see ‘TIME’ switch) expires the LED strip is
switched off.
5 Slowly on dimmer Pushing the pushbutton will slowly turn on the LED strip to full
brightness. The duration to achieve maximum brightness is
determined by the ‘TIME’ switch.
Pushing the pushbutton while the LED strip is already on will
switch it off immediately.
6 Slowly off dimmer Pushing the pushbutton will switch on the LED strip to full
brightness.
Pushing the pushbutton when the LED strip is on will slowly
decrease brightness until the LED strip is off. The duration to
switch the LED strip to off is determined by the ‘TIME’ switch.
Pushing the pushbutton during decreasing brightness will turn
the LED strip back to full brightness.
7 Slowly on/off dimmer Pushing the pushbutton will slowly turn on the LED strip to full
brightness.
Pushing the pushbutton when the LED strip is on will slowly
decrease brightness until the LED strip is off.
The duration to achieve maximum brightness or to switch the
LED strip off is determined by the ‘TIME’ switch.
Remarks:
When the ‘TIME’ rotary switch is set to ‘0’ the dimmer module will always work in instant control, no matter what
operating mode is set. On other words, the LED strip will light up as long as the pushbutton is pushed.
When the ‘TIME’ rotary switch is set to ‘F’ the dimmer module will not automatically switch off or the dimming speed
will be maximal when the module is set to slowly on, slowly off or slowly on/off mode.
