V-PRO SMART DIMMERSWITCHES

OVERVIEW

Thank you for choosing a VARILIGHT V-Pro Smart intelligent
programmable rotary control dimmerswitch. Us e only on an electricity
supply of 230 volts AC.
IMPORTANT: Read ALL sections below before installing this
dimmerswitch.
The V-Pro Smart master dimmer is suitable for 1-way circuits. For 2­way (or multi-way) circuits, use a V-Pro Smart master dimmer with one
or more supplementary controllers. V-Pro Smart rotary dimmers cannot
be used in c onjunction with conventional switches in a 2-way circuit.
Use only on an electricity supply of 230V~.
This product complies with British and European Safety Regulations
(IEC 669-2-1 or BSEN60669-2-1) 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.

LOADING

Maximum loads f or V-Pro Smart dimmerswitches (please see
www.varilight.co.uk for latest loading advice);

Always observe the recommended maximum load.

Lighting
Load

Dimmable Mains
& Low Voltage
LEDs

THIS SWITCH IS SUITABLE FOR
 Most dimmable LEDs

THIS SWITCH IS NOT SUITABLE FOR:

 Non-dimmable fluorescent bulbs and tubes;
 Wire-wound or toroidal transformers;
 Electric motors

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 dimmerswitch 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*.
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 (eg. Use a 50VA, 60VA 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 dimmer turning itself off. If this

happens, change your transformer(s) (VARILIGHT transformer(s)
recommended); or remove one (or some) transformer(s) from the
circuit; or choose a higher rated dimmer instead. If a transformer
specifies Triac dimming, use a dimmer from the V-Com series.
* If a transformer appears as a highly inductive load, e.g. W ire-wound
or toroidal transf ormers, the dimmer will not work. To protect itself it
will turn off within 1 second.

ADVICE ON CHANGING LIGHT BULBS

Always turn off the mains power when light bulbs controlled by your V­Pro Smart dimmers are replaced. If you change the type of light bulb
then restore factory settings as described under “Programming”.

WARNING: Do not apply products with metal f aceplates directly
to freshly plastered or damp surfaces as product may tarnish. If in
doubt, use polythene as a temporary gasket to protect the
product. Do not use masking tape on metal faceplates.

has not been used with an incompatible load, fluorescent tubes, or
overloaded beyond its rating, and has only been used on a 200-250V
a.c. power supply.
b) The dimmer module has not been tampered with or taken apart.
c) The unit is securely packed and safely returned to either address
listed in the overview section above, together with a letter stating the
guarantee registration number below, the date and place of purchase,
your contact details and return address, the type and wattage of the

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, then remove the existing switch and
disconnect the wiring from the switch terminals at the rear, taking note
of the present wiring of the switch and the marking on the terminals.
Where 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 double­sized plates to wall boxes with 120.6mm fixing centres. Dimmers can
be fitted into a box with a minimum depth of 25mm for Classic plated
products, or 35mm for Ultraflat and Screwless. A box having 4 fixing
lugs cannot be used without modifying it. The top and bottom lugs
must be broken off or bent flat.

3. To connect the wiring for 1-way or 2-way circuits refer to the wiring
diagrams, or the text under the heading "1-Way, 2-Way and Multi-Way
Circuits" on the other side of this leaflet. T ake c are 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 having a metal plate must be earthed by means of
the earthing point on the faceplate.

5. After connecting the wires screw the dimmerswitch gently into the
wall box so that 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 c ould damage a dimmer and make
the guarantee invalid.

CONTROL TIPS

There are some extra functions of this dimmer that c an be used
alongside the regular push on/off and rotary dim controls.
A sharp turn up will set the dimmers to maximum brightness, with a
sharp turn down setting them to minimum brightness. Either of
these can be performed from off. Turning the dimmer slowly in either
direction from off will bring the dimmers on at minimum brightness,
allowing you to ramp up from a very low level.

PROGRAMMING

You can a change the s ettings of this dimmer via use of the control
knob. You can see instructions on how to do so below:

*Once set, leave the dimmer for 3 seconds. The lights will flash to show the

new level has been set, and the dimmer will return to norm al operation.
**When holding down for 15 seconds, the lights will flash on after 6
seconds. This is to be ignored.

Boost Function Explained

Some LED lights require a large amount of power to come on and so do not
illuminate at low brightness levels. The Boost functi on caters for LED lights
that require more power at start-up by raising the startup brightness level,
and putting the brightness back to the specified level.

Set to minimum brightness and hold the button for 6
seconds. The lights will then come on and allow you
to adjust the minimum brightness. *
Set to maximum and hold the button for 6 seconds.
The lights will then come on and allow you to adjust

seconds. Once reset, the light will come on and
fade to off. **
Turn the dimmer off and hold the button down for 6
seconds. The lights will pulse and go off. Press the
dimmer once for mode 1, twice for mode 2, or
thrice for mode 3. The default mode for this dimmer
is mode 2.
Turn the dimmer off and hold the button down for 15
seconds. The lights will then come on and allow you
to set the boost level. *

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

In 1-way lighting circuits the light(s) are controlled by one switch. This
dimmer should replace that switch. The live wire must be connected to
the terminal marked "LIVE" and the "load" wire to the terminal marked
"LOAD". To fit 2, 3 or 4-gang dimmers treat each group of terminals at
the back of the unit as a s eparate dimmer. You may also need a short
length of wire to connect together the "LIVE" terminals if only one live
wire is present.
For 2-way or Multi-way circuits (where the light(s) are controlled by
more than one switch) use this dimmer and any number of V-Pro
Smart supplementary controllers (total cable length from the master to
the last supplementary controller should be no more than 50m)
following the wiring diagrams below. It is not possible to use a
conventional switch in combination with this type of dimmer. Follow the
same wiring as for 1-way circuits with three (or two) wires linking each
supplementary controller using the “LOAD” terminal, “S-LINK” terminal
and “LIVE” terminal. For more information please refer to the wiring
diagrams below.
