INSTRUCTIONS FOR VARILIGHT HIGH
POWER V-PRO DIMMERSWITCHES

OVERVIEW

Thank you for choosing a VARILIGHT V-Pro intelligent programmable dimmer switch. Use only on an electricity supply of 230V 50Hz AC.
IMPORTANT : Read ALL sections below before installing this dimmer switch.
V-Pro dimmers are set to run in trailing-edge mode (MODE 1) by default. This versatile model is suitable for most types of lighting, including many dimmable LEDs. It is also gentler on the load. An alternative trailing-edge mode (MODE 3) may improve the performance of some dimmable LEDs and dimmable CFLs. Some other lighting loads, including some types of LED, perform best with leading-edge control. This dimmer can also be set to run in the leading edge (MODE 2) with certain types of LED light. To change the mode, follow the instructions under “Programming” below.
To optimize the dimming range for LED lighting in particular the minimum brightness setting of the dimmer can be adjusted [see “Adjusting the Minimum Brightness” under “Programming”]. 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.

THIS SWITCH IS NOT SUITABLE FOR
× Non-dimmable fluorescent bulbs and tubes
× Wire-wound or toroidal transformers
× Electric motors (e.g. Fans)

OVERLOAD PROTECTION :
This dimmer switch is protected against overload. If an overload occurs it will automatically turn off until the overload is removed and the dimmer switch is switched off and then switched back on again. However, if the dimmer switch receives a total short-circuit it may be damaged beyond repair.
TRANSFORMERS
Use only with quality dimmable electronic transformers. For optimum performance choose VARILIGHT transformers. Do not use wire-wound or toroidal transformers. 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, 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 features 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.

PROGRAMMING

OPTIMISING THE PERFORMANCE OF YOUR DIMMERSWITCH
When you first install the 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 dimming performance by changing the driving mode. [See “Changing the driving mode” below.] You can always reset to trailing-edge MODE

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 a minimum, you can try reducing the minimum brightness setting of the dimmer.

Switch on and set the dimmer knob to the MINIMUM position (turn fully anticlockwise).
Turn the lights off and back on again. OFF – ON, roughly once per second.
Repeat step 2 at least twice more. OFF – ON – OFF – ON, roughly once per second.
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.
Turn the knob fully clockwise. The lights will come on and allow you to adjust the minimum brightness.
Slowly adjust to the brightness that you are happy with as the minimum. Leave the dimmer in this position.
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 that the dimmer has returned to normal operation.
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.

Switch off and set the dimmer knob to the MAXIMUM position (turn fully clockwise).
Turn the lights on and back off again. ON – OFF, roughly once per second.
Set the dimmer knob to the MINIMUM position (turn fully anticlockwise).
Turn the lights on and back off again. ON – OFF, roughly once per second.
Set the dimmer knob to the MAXIMUM position (turn fully clockwise).
Turn the lights on.
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.
Turn the knob fully anticlockwise. The lights will come on and allow you to adjust the maximum brightness.
Adjust the brightness that you are happy with as the maximum. Leave the dimmer in this position.
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.
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.

Switch on and set the dimmer knob to the MAXIMUM position (turn fully clockwise).
Turn the lights off and back on again. OFF – ON, roughly once per second.
Repeat step 2 at least twice more. OFF – ON – OFF – ON, roughly once per second.
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.
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.
The lights will FLASH 3 TIMES or TWICE to show which mode the dimmer is in. The dimmer can be operated normally in the new model.

N.B. The dimmer is designed to protect itself against the excess current. 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 follows.

Switch on and set the dimmer knob to the MAXIMUM position.
Turn the lights off and back on again. OFF – ON, roughly once per second.
Repeat step 2 at least twice more. OFF – ON – OFF – ON, roughly once per second.
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.
Within 5 seconds, repeat steps 2 and 3. OFF – ON – OFF – ON – OFF – ON, roughly once per second.
The dimmer will reset all its settings to factory defaults. The lights will come on, then fade away to off.
The dimmer will now operate in trailing-edge mode 1 and the minimum brightness setting will be reset to the factory default.
Continue to use the dimmer as normal.

PROGRAMMING (Continued)

DRIVE FUNCTION
Some LED lights to 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

Switch off and set the dimmer knob to the MINIMUM position (turn fully anticlockwise).
Turn the lights on and back off again. [ON-OFF] roughly once per second.
Set the dimmer knob to the MAXIMUM position (turn fully clockwise)
Turn the lights on and back off again. [ON-OFF] roughly once per second.
Set the dimmer knob to the MINIMUM position (turn fully anticlockwise)
Turn the lights on.
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.
Slowly increase the power until your lamps illuminate. Leave the dimmer in this position.
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 the dimmer has returned
to normal operation.
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

Switch off the dimmer and set the dimmer knob to the MAXIMUM position (turn fully clockwise).
Turn the lights on and back off again twice. ON – OFF – ON – OFF, roughly once per second.
Set the dimmer knob to the MINIMUM position (turn fully anticlockwise).
Turn the lights on and back off again twice. ON – OFF – ON – OFF, roughly once per second.
Set the dimmer knob to the MAXIMUM position (turn fully clockwise).
Turn the lights ON – OFF – ON, roughly once per second.
The lights will step up and down in brightness to show that the dimmer has returned to normal operation.
Continue to use the dimmer as normal, with your new Child Lock setting.
To disable Child Lock, repeat the whole procedure again.

1-WAY, 2-WAY AND MULTI-WAY CIRCUITS

Your VARILIGHT V-Pro intelligent dimmer switch 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 dimmer switch should replace this switch. See Figure 1. Remove your old switch and copy the wiring configuration for your dimmer switch. Connect wires either way round to the ‘C’ terminal and one of the ‘L’ terminals. The other ‘L’ terminal is not used in a 1-way circuit.
2-WAY CIRCUITS
2-way lighting circuits have two switches turning 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 dimmer switch 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” a terminal of the dimmer switch. The wires fit into the other two terminals of the old switch should be fitted either way round into terminals “L1” and “L2” of the dimmer switch.
MULTI-GANG DIMMERSWITCHES
To fit 2 gangs (or 3 or 4 gangs) dimmer switches treat each group of terminals at the back of the unit as a separate dimmer switch wiring them into the lighting circuits as described above. If required, one terminal from each dimmer module may be joined together with a short length of wire to copy the wiring configuration of the old switch.
