INSTRUCTIONS FOR VARILIGHT
V-COM DIMMERSWITCHES
OVERVIEW
Thank you for choosing a VARILIGHT V-Com intelligent programmable
dimmerswitch. Use only on an electricity supply of 230V 50Hz AC.
IMPORTANT:
Read
ALL
sections
below
before
installing
this
dimmerswitch.
V-Com dimmers are leading-edge and designed to control TRIAC dimmable
LED lighting. To optimise the dimming performance with LED lighting see
“Programming” overleaf. For information on compatibility with other types of
lighting please see “Loading” overleaf.
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.
LOADING
Always observe the recommended minimum and maximum loads
stated on the dimmer.
For mixed loads, follow the LED rating.

THIS SWITCH IS RECOMMENDED FOR
LED Lighting Requiring TRIAC dimming
THIS SWITCH IS ALSO COMPATIBLE WITH
Good quality dimmable low voltage transformers [see “Transformers"]
GU10 or similar good quality mains halogen bulbs; [Choose V-Plus
Series Dimmers for the best performance with halogen lighting]
Mains voltage incandescent GLS or candle-shaped bulbs
THIS SWITCH IS NOT SUITABLE FOR
Fluorescent bulbs and tubes
Electric motors
OVERLOAD PROTECTION
This dimmerswitch is protected against overheating and overload. If an
overload occurs the dimmer will turn off. In this case, switch off the dimmer,
remove the overload and switch back on again. However, if the
dimmerswitch receives a total short-circuit it may be damaged beyond
repair.
TRANSFORMERS
Use only with quality dimmable 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 (e.g. 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 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.

GUARANTEE
In case of any defect, return the dimmer to our service department. Varilight
undertakes to repair or replace, at its discretion, goods which have become
defective within 10 years of purchase, solely as a result of faulty materials
and workmanship, provided that:-
a) The unit has been correctly fitted according to the instructions and has
not been used with an incompatible load, fluorescent tubes, or overloaded
beyond its rating, and has only been used on a 230V 50Hz AC power
supply.
b) The dimmer module has not been tampered with or taken apart.
c) The unit is securely packed and safely returned to Service Department,
Carylls Lea, Faygate, Horsham, West Sussex, RH12 4SJ (Tel. (01293)
223333) together with a letter stating the guarantee registration number
below, the date and place of purchase, the type and wattage of the lighting
or other load being controlled and the details of the fault. This guarantee
states Varilight’s entire liability, which does not extend to cover
consequential loss or damage or installation costs arising from a defective
product. The guarantee does not apply to problems arising from any
incompatibility between your lamps and the dimmer switch. This guarantee
does not in any way affect the statutory rights of the purchaser and is
offered so that you may have the benefit of our technical facilities.
GUARANTEE REGISTRATION NUMBER K007.
FITTING YOUR DIMMERSWITCH
Read these instructions 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.
3. Dimmerswitches on single-sized plates can be fitted to wall boxes having
60.3mm screw fixing centres and those with double-sized 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 lugs must be broken off or bent
flat.
4. To connect the wiring for 1-way or 2-way circuits refer to the diagrams
overleaf 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.
5. Dimmerswitches having a metal front plate must be earthed by means of
the earthing point on the dimmer.
6. 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.
7. Once installation is complete. Switch on the mains supply and switch on
the dimmer, turning the control knob to give the desired light level.
Important:
Disconnect the dimmer before carrying out insulation resistance
testing. Failing to do so could damage a dimmer and make the guarantee
invalid.
1-WAY, 2-WAY & MULTI-WAY CIRCUITS
Your VARILIGHT V-Com 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'
terminals. The other 'L' terminal is not used in a 1-way circuit. (P.T.O)
