Thank you for choosing a VARILIGHT dimmerswitch. This
dimmerswitch is designed for mains voltage lighting and can
be used to dim VARILIGHT electronic transformers as well
as VARILIGHT DigiFlux Dimmer Dimmable Energy-Saving
Light Bulbs. Use only on an electricity supply of 230 volts
AC.
IMPORTANT: Read ALL sections below before installing this
dimmerswitch.

OVERLOADING AND UNDERLOADING
Dimmers must not be overloaded or underloaded. Check the
label on the back of your dimmerswitch for the maximum
ratings of each module and adjust this if necessary according
to the load type (see above). The minimum loads for each
are also shown on the label.
If the dimmerswitch makes the lights flicker it is likely that it is
underloaded. For optimum energy-saving it is recommended
that the minimum load for any dimmerswitch is 100W. This
way you will save more energy and still be able to dim the
lights to the level that you want. Don't forget that the added
advantage of a dimmerswitch is that it will also extend bulb
life.

TRANSFORMERS
This dimmer can be used to control VARILIGHT dimmable
electronic transformers (the load is calculated by adding the
wattages of the transformers, eg. 7 x 50W transformers =
350W and can be dimmed using a 400W dimmer). Always
choose quality dimmable electronic transformers such as
VARILIGHT transformers.
For electronic transformers from other manufacturers we
recommend a maximum of 5 electronic transformers per
dimmer circuit. Noise levels may vary depending upon the
type and quantity of transformers used.

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 200-250V a.c. power supply.
b) The dimmer module has not been tampered with or taken
apart. However, for your convenience, it is perfectly in order
to remove a faulty dimmer module from multi-gang dimmers
by pulling off the knob and unscrewing the nut under the
knob. You will then still have the remaining modules working
whilst we service your faulty module.
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.

FITTING YOUR DIMMER
1-WAY & 2-WAY CIRCUITS AND MULTI-GANG
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 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.
3. To connect the wiring for 1-way or 2-way circuits refer to
the diagrams overleaf under the heading "Typical Lighting
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 having a metal front 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, turning the control knob to give
the desired light level.
A slight buzzing may be heard from the dimmerswitch in
operation. This is quite normal.
Important: Disconnect the dimmer before carrying out insulation
resistance testing. Failing to do s o could damage a dimmer and
make the guarantee invalid.
Reconnect the wires either way round to the “C” terminal and
Figure 1. Using a 1-W ay Dimmerswitch
(For single switches or each module of a multi-gang)
the “L1” terminal.

(For single switches or each module of a multi-gang)
Dimmer must replace only one of the 2-way switches
There are two basic types of lighting circuit, so make sure
you have the correct dimmerswitch for your lighting circuit.
1. 1-Way Circuits
In 1-way lighting circuits the light or lights are controlled by
one switch. Your dimmerswitch replaces this switch and
can be a 1-way rotary model (Figure 1), or a 1 or 2 way
push-on/push-off model (Figure 2).
(The advantage of a push-on/push-off dimmerswitch is that
the dimmer can be switched on and off with a push action,
while keeping the lighting at the level you have chosen.)
Remove your old switch and copy the wiring configuration
for the dimmerswitch. The wires from your old switch can
be connected either way round to the "C" and "L1"
terminals of the dimmerswitch. If you are using a pushon/push-off dimmerswitch there is a spare terminal (L2)
that you will not need to use for a 1-way circuit.
2. 2-Way Circuits
2-way lighting circuits have two switches turning the same
light or lights on and off from two different locations (e.g..
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 3 and 4 which show typical 2-way
circuits. Remove your old switch and copy the wiring
configuration for the dimmer.
Remove your old switch and copy the wiring configuration
for your dimmerswitch. The wire(s) fitted in the "common"
terminal of the old switch should be fitted into the "C"
termnal 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.
Note: Dimmer switches have “C” next to “L1” & “L2”
whereas most switches have “C” at the opposite end to
“L1” & “L2”.
3. Multi-Gang
Dimmerswitches (with 2, 3
or 4 control knobs)
To fit multi-gang
dimmerswitches treat
each group of terminals at
the back of the unit as a
separate dimmerswitch 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.

(For single switches or each module of a multi-gang)
Reconnect the wires either way round to the “C” terminal and
the “L1” terminal.
Figure 4. Using a 2-W ay Dimmerswitch
(For single switches or each module of a multi-gang)
Dimmer must replace only one of the 2-way switches
