WARNING
V-PRO DIMMERSWITCHES
OVERVIEW
Thank you for choosing a VARILIGHT V-Pro intelligent programmable
dimmerswitch. Use only on an electricity supply of 230VAC 50Hz.
IMPORTANT: Read ALL sections below before installing this dimmerswitch.
V-Pro dimmers are set to run in trailing-edge mode (MODE 1) by default. This
versatile mode is suitable for most types of lighting recommended below.
The alternative trailing-edge mode (MODE 3) may improve the performance of
some dimmable LEDs. Some other lighting loads, including some types of LED,
perform best in Mode 2. T his is a simulated leading edge mode (not TRIAC)
which is suitable for use with certain types of LED light. T o change the mode,
follow the instructions under “Programming” below.
This product complies with European Safety Regulations (IEC 669-2-1 or BSEN
60669-2-1) when used in lighting circuits containing MCBs (miniature circuit
breakers). These can be rated at 6A, 10A or 16A (preferably 6A for lighting
circuits).Your guarantee is not affected if you have an older lighting circuit
protected by fuse wire links.
At the time of installation it is your responsibility to make sure that the lamps in
your installation are visibly on, even at the lowest brightness setting [see
“Adjusting the Minimum Brightness” under “Programming”]. This will allow your
installation to comply with the EU EcoDesign Regulation 1194/2012. To
optimise the dimming range for LED lighting in particular the minim um
brightness setting of the dimmer can be adjusted [see “Adjusting the Minimum
Brightness” under “Programming”].

OVERLOAD PROTECTION:
This dimmerswitch is protected against overload. If an overload occurs it will
automatically turn off until the overload is removed and the dimmerswitch is
switched off and then switched back on again. However, if the dimm erswitch
receives a total short-circuit it may be damaged beyond repair.
TRANSFORMERS
Use only with quality dimm able electronic transformers. For optimum
performance choose VARILIGHT transformers. Do not use with wirewound or
toroidal transformers, or TRIAC dimm able drivers (choose V-Com for TRIAC
dimmable. To calculate load, add the VA ratings of the transformers (not the
wattage of the bulbs). Choose transformers with a maximum rating close to
their lamp load (e.g. Use a 50VA, 6 0VA or 70VA transformer to control a 50W
low voltage bulb).
N.B. Certain transformers may not behave according to their power rating
when used with a dimmer. An overload will result in the safety feature s
switching the dimmer off. If so, change your transformer(s) (VARILIGHT
transformer(s) recommended); or remove one (or some) transformer(s) from the
circuit; or choose a higher rated dimmer.

polythene as a temporary gasket to protect the
product. Do not use masking tape on metal faceplates.
: Do not apply products with metal
FITTING YOUR DIMMERSWITCH
Read the instructions below carefully. Incorrect installation may damage the dimmer
beyond repair. In case of any doubt or difficulty consult a qualified electrician.
1. Switch off at the mains, and then remove the existing switch from the wall. Take
note of the present wiring of the switch and the marking on the terminals. Disconnect
the existing switch and connect the dimmerswitch. W here there are two or more wires
together in the old switch, they must be kept together in the dimmerswitch.
2. Ensure that any wall box is free of plaster lumps or projecting screw heads.
Dimmerswitches on single-sized plates can be fitted to wall boxes having 60.3mm
screw fixing centres and those with double-s ized plates to wall boxes with 120.6mm
fixing centres. Most models can be fitted into a box with a minimum depth of 25mm. A
box having 4 fixing lugs cannot be used without modifying it. The top and bottom lu gs
must be broken off or bent flat.
3. To connect the wiring for 1- way or 2-way circuits refer to the diagrams to the right
under the heading "1-Way, 2-Way and Multi-Way Circuits". Take care that no bare
wires project out of the terminals. Keep wires together in a terminal if they were
together in your old switch.
4. Dimmerswitches fitted to a metal faceplate must be earthed by means of the
marked earthing point on the faceplate.
5. After connecting the wires screw the dimmerswitch gently into the wall box so th at
the front plate is not distorted or cracked. Do not trap the wiring between the rear of
the dimmer and the back of the wall box.
6. Once installation is complete. Switch on the mains supply and switch on the
dimmer.
Important: Disconnect the dimmer before carrying out insulation resistance testing.
Failing to do so could damage a dimmer and make the guarantee invalid.

PROGRAMMING
OPTIMISING THE PERFORMANCE OF YOUR DIMMERSWITCH
When you first install t he dimmer switch it will automatically default to trailing-edge
MODE 1. This mode is the best one for most types of lighting but for some lighting
loads you may be able to improve the dim ming performance by changing the drivin g
mode. [See “Changing the driving mode” below.] You can always reset to trailingedge MODE 1. Additionally, the minimum brightness setting of the dimmer can be
adjusted to achieve the optimum dimming range for a particular load as follows. (You
may also need to refer to these instructions if you change your lights to a different
type at a later date so please keep them for reference).
ADJUSTING THE MINIMUM BRIGHTNESS
If your lights are flickering when they are dimmed to a low level you can increase the
minimum brightness setting of the dimmer, which may prevent this from happening. If
the lights are brighter than you would like when the dimmer is set to minimum, you
can try reducing the minimum brightness setting of the dimmer.
1. Switch on and set the dimmer knob to the MINIMUM position (turn fully anticlockwise).
2. Turn the lights off and back on again. OFF – ON, roughly once per second.
3. Repeat step 2 at least twice more. OFF – ON – OFF – ON, roughly once per
second.
4. The lights will step up and down in brightness to show that the dimmer is in
CONFIGURATION MODE, then either stay at a low light level or go off.
5. Turn the knob fully clockwise. The lights will come on and allow you to adjust the
minimum brightness.
6. Slowly adjust to the brightness that you are happy with as the minimum. Leave the
dimmer in this position.
7. After 3 seconds the dimmer will notice that you have stopped adjusting the
minimum. The lights will step up and down in brightness to show t hat the dimmer
has returned to normal operation.
8. Continue to use the dimmer as normal, with your new minimum brightness.
ADJUSTING THE MAXIMUM BRIGHTNESS
If your lights are flickering when they are set to a high brightness level you can
decrease the maximum brightness setting of the dimmer, which may prevent this from
happening. If the lights are not as bright as you would like when the dimmer is set to
maximum, you can try increasing the maximum brightness setting of the dimmer.
1. Switch off and set the dimmer knob to the MAXIMUM position (turn fully
clockwise).
2. Turn the lights on and back off again. ON – OFF, roughly once per second.
3. Set the dimmer knob to the MINIMUM position (turn fully anticlockwise).
4. Turn the lights on and back off again. ON – OFF, roughly once per second.
5. Set the dimmer knob to the MAXIMUM position (turn fully clockwise).
6. Turn the lights on.
7. The lights will step up and down in brightness to show that the dimmer is in
CONFIGURATION MODE, then either stay at a low light level or go off.
8. Turn the knob fully anticlockwise. The lights will come on and allow you to adjust
the maximum brightness.
9. Adjust the brightness that you are happy with as the maximum. Leave the
dimmer in this position.
10. After 3 seconds the dimmer will notice that you have stopped adjusting the
maximum. The lights will step up and down in brightness to show that the
dimmer has returned to normal operation.
11. Continue to use the dimmer as normal, with your new maximum brightness .
CHANGING THE DRIVING MODE
You may be able to improve the performance of your lamps by changing the driving
mode to MODE 3, or with some types of lamp MODE 2.
NB. It has been noted that some LEDs do not show the programming as well as
others. If you are having difficulty seeing the programming steps, you can replace one
LED lamp with a halogen one for the duration of the programming in order to see the
steps more clearly.
1. Switch on and set the dimmer knob to the MAXIMUM position (turn fully
clockwise).
2. Turn the lights off and back on again. OFF – ON, roughly once per second.
3. Repeat step 2 at least twice more. OFF – ON – OFF – ON, roughly once per
second.
4. The lights will step up and down in brightness to show that the dimmer is in
CONFIGURATION MODE, then either stay at a low light level or go off.
5. To select MODE 3, first turn the knob fully anti-clockwise then fully clockwise. For
MODE 2, just turn the knob fully anti-clockwise and leave it for a couple of
seconds.
6. The lights will FLASH 3 TIMES or TWICE to show which mode t he dimmer is in.
The dimmer can be operated normally in the new mode.
N.B. The dimmer is designed to protect itself against excess c urrent. Some types of
LED light will draw too much current in MODE 2. In this case the dimmer will switch
back automatically to MODE 1. The dimmer will turn off altogether if it is overloaded in
MODE 1 or MODE 3.
To manually return the dimmer to MODE 1 follow the same procedure and at step 5
turn the knob fully anti-clockwise. The lights will FLASH ONCE to indicate that you
have successfully returned the dimmer to MODE 1.
[To check which mode the dimmer is operating in omit step 5.]
RESETTING THE DIMMER
If you change your lights you can reset the dimmer to the factory default minimum
brightness setting and re-launch trailing-edge mode 1 as f ollows.
1. Switch on and set the dimmer knob to the MAXIMUM pos ition.
2. Turn the lights off and back on again. OFF – ON, roughly once per second.
3. Repeat step 2 at least twice more. OFF – ON – OFF – ON, roughly once per
second.
4. The lights will step up and down in brightness to show that the dimmer is in
CONFIGURATION MODE, then either stay at a low light level or go off.
5. W ithin 5 seconds, repeat steps 2 and 3. OFF – ON – OFF – ON – OFF – ON ,
roughly once per second.
6. The dimmer will reset all its settings to factory defaults. The lights will come on,
then fade away to off.
7. The dimmer will now operate in trailing-edge mode 1 an d the minimum brightnes s
setting will be reset to the factory default.
8. Continue to use the dimmer as normal.
PROGRAMMING (Continued)
DRIVE FUNCTION
Some LED lights require a large amount of power to come on and so do not illuminate
at low brightness levels. This dimmer is equipped with a DRIVE function to cater for
LED lights that require more power at start-up. To enable the DRIVE function
1. Switch off and set the dimmer knob t o the MINIMUM position (turn fully
anticlockwise).
2. Turn the lights on and back off again. [ON-OFF] roughly once per second.
3. Set the dimmer knob to the MAXIMUM position (turn fully clockwise)
4. Turn the lights on and back off again. [ON-OFF] roughly once per second.
5. Set the dimmer knob to the MINIMUM position (turn fully anticlockwise)
6. Turn the lights on.
7. The lights will step up and down in brightness to show that the dimmer is in
CONFIGURATION MODE, then either stay at a low light level or go off.
8. Slowly increase the power until your lamps illuminate. Leave the dimmer in this
position.
9. After 3 seconds the dimmer will notice that you have stopped adjusting the
DRIVE. The lights will step up and down in brightness to show that t he dimmer
has returned to normal operation.
10. Continue to use the dimmer as normal with your new DRIVE level.
To disable the DRIVE function, repeat the above but omit step 8.
CHILD LOCK
You can prevent your dimmer from accidentally going into programming mode by
following these instructions. To enable the Child Lock feature
1. Switch off the dimmer and set the dimmer knob to the MAXIMUM position (turn
fully clockwise).
2. Turn the lights on and back off again twice. ON – OFF – ON – OFF, roughly once
per second.
3. Set the dimmer knob to the MINIMUM position (turn fully anticlockwise).
4. Turn the lights on and back off again twice. ON – OFF – ON – OFF, roughly once
per second.
5. Set the dimmer knob to the MAXIMUM position (turn fully clockwise).
6. Turn the lights ON – OFF – ON, roughly once per second.
7. The lights will step up and down in brightness to show that the dimmer has
returned to normal operation.
8. Continue to use the dimmer as normal, with your new Child Lock setting.
9. To disable Child Lock, repeat the whole procedure again.
1-WAY, 2-WAY AND MULTI-WAY CIRCUITS
Your VARILIGHT V-Pro intelligent dimmerswitch is suitable for 1-way or 2-way lighting
circuits. It has a push on/push off action to switch and a rotary action to dim. There
are 3 screw terminals per module.
1-WAY CIRCUITS
In 1-way lighting circuits each light is controlled by one switch.
Your dimmerswitch should replace this switch. See Figure 1. Remove your old switch
and copy the wiring configuration for your dimmerswitch. Connect wires either way
round to the 'C' terminal and one of the 'L' t erminals. The other 'L' terminal is not used
in a 1-way circuit.
2-WAY CIRCUITS
2-way lighting circuits have two switches t urning the same lights on and off from 2
different locations (eg. at the top and bottom of the stairs). You must only replace one
of these switches with a dimmerswitch or the lights will flicker. See Figures 2 and 3
which show typical 2-way circuits. Remove your old switch and copy the wiring
configuration for the dimmer.
The wire(s) fitted in the "common" terminal of the old switch should be fitted into the
"C" terminal of the dimmerswitch. The wires fitted into the other two terminals of the
old switch should be fitted either way round into terminals "L1" and "L2" of the
dimmerswitch.
MULTI-GANG DIMMERSWITCHES
To fit 2 gang (or 3 or 4 gang) dimmerswitches treat each group of terminals at the
back of the unit as a s eparate dimmerswitch wiring them into the lighting circuits as
described above. If required, one terminal from each dimmer module may be joine d
together with a short length of wire to copy the wiring configuration of the old switch.
