Intelligent Electronic Timer Switch
1 Way
Thank you for choosing VARILIGHT. This switch is suitable for 1-Way Circuits only. Use only on an electricity supply of 200
to 250 volts a.c.. This switch features versatile trailing-edge control making it suitable for a wider range of applications.
THIS SWITCH IS SUITABLE FOR
Mains voltage GLS bulbs;
Most dimmable electronic low voltage transformers
(including those requiring trailing-edge control)
[see “Transformers" box on the right ]:
GU10 or similar HiSpot mains halogen bulbs
Candle bulbs
Never exceed the recommended maximum load
[see "Safety Features" box below ]
THIS SWITCH IS NOT SUITABLE FOR
Fluorescent lights or compact fluorescent bulbs;
Wire-wound or toroidal transformers;
Electric motors or fans
TRANSFORMERS
Use only on dimmable Electronic Transformers
To calculate load, add the VA ratings of the transformers (not the
wattage of the bulbs). There is an absolute maximum of 5
transformers on any dimmer circuit (except with VARILIGHT LV
Transformers when you can add the bulb wattages up to the dimmer
"max. load" and use up to 10 transformers). Choose transformers
with a maximum rating close to their lamp load (eg. Use a 60VA
transformer to control a 50W low voltage bulb); except with
VARILIGHT LV Transformers when any lamp loading will work.
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 of this dimmer turning down the brightness. If so change
your transformers to ones which do not appear as an overload,
remove one (or some) transformer(s) from the circuit or choose a
higher rated dimmer instead. (This does not apply to VARILIGHT
transformers.)
FITTING THE SWITCH
Read the instructions below carefully before beginning. In case of any doubt or difficulty consult a qualified electrician.
1. Switch off at the mains.
2. 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 this one.
3. Ensure that any wall box is free of plaster lumps or projecting screw heads. Use 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, refer to the diagram below. Switches with a metal front plate must be earthed by means of the
earthing point on the switch. You must ensure that all wires are sleeved fully and only enough bare wire is showing to
connect to the terminals. Push wires deep into terminals and tighten terminal screws so that wires are held securely. No
bare wires should protrude from the terminals.
5. After connecting the wires, screw the dimmer gently into the wall box. Do not trap the wiring between the rear of the
dimmer and the back of the wall box.
6. Turn on the mains electricity.
Your VARILIGHT Timer Switch is suitable for 1-way circuits. It cannot be used conjunction with another switch in a 2-way
circuit. In 1-way lighting circuits each light is controlled by one switch. This dimmer replaces that switch. The live wire must
be connected to the terminal marked "Liveο" and the "load" wire to the terminal marked " ". This means that
the terminal marked “ ” is connected directly to the light(s) (or transformers for low voltage lighting).

SAFETY FEATURES:
This dimmer will protect itself against overload, short-circuit, over-temperature and
over-voltage. To avoid these safety features turning the dimmer down or off, make
sure you load the dimmer correctly by carefully reading the advise in this leaflet.
If a gross overload or short-circuit occurs the dimmer will automatically turn off until
the overload or short-circuit is removed and the dimmer is switched on again.
Even if the dimmer is slightly overloaded it will react by turning down the brightness
progressively. If it can find a comfortable operating level it will stay on with the light(s)
at reduced brightness, otherwise it will switch off.
This dimmer should not be used on wire-wound transformers. If it is mistakenly
connected to a wire-wound transformer the dimmer will warn the user by coming on
at a low brightness for 2 seconds before switching off completely. N.B. To prevent
damage to itself, the dimmer will only perform this warning 3 times. After this it will
block further use until it is disconnected from and then re-connected to the mains
electricity supply.

OPERATION OF THE SWITCH
Factory Setting
This timer switch is pre-programmed so that when you touch the button it will bring the lights up gently to full brightness. The
lights will stay on for 5 minutes after which they will dim down to off over 30 seconds.
Programming The Switch
You can program the switch to (a) alter the time-on period or to (b) alter the brightness of the lights while they are on.
To begin programming, tap the button with your finger 6 or more times in quick succession (each tap causes the lights(s) to
turn on or off). After 6 or more taps, the lights will step up and down once and go off to indicate you are in programming mode.

Is it normal for the dimmer to be warm to the touch even when the lights are off? A small current passes
through the dimmer even when it is off to maintain its memory. This can cause the dimmer to feel warm to the touch.
Should I be concerned if the dimmer is very warm during use? The dimmer will become warm during use. The
more lights the dimmer is controlling, the warmer it will become. On its maximum load the dimmer can become very
warm. As long as you have not overloaded the dimmer, this is no cause for alarm.
What happens if I have a power cut? If for any reason the power is lost to the dimmer, the dimmer will be reset to
its factory setting. Any settings you have applied to the dimmer will need to be re-programmed. Keep these instructions
safe so that you can use them again if this occurs.
Can this dimmer be used in 2-way circuits? No, this is a 1 way dimmer. It cannot be used to control lights that are
also controlled by another switch elsewhere.
The touch button does not work properly. This can be caused by the live and load wires being in the wrong
terminals (see wiring diagram overleaf).
The light(s) come(s) on dim for 2 seconds and then the lights go off. This could be the dimmer warning you that
it is connected to a wire-wound transformer(s). It cannot be used to control wire-wound transformers. (N.B. In this
situation, the dimmer may block any further use until it is disconnected from the mains.) Either replace the
transformer(s) with a dimmable electronic transformer(s) or use the dimmer elsewhere on a suitable load.
The dimmer keeps turning the lights down. The dimmer is doing this because it is overloaded. If it can find a
comfortable operating level it will stay on with the light(s) at reduced brightness, otherwise it will switch off. One solution
could be to use lower wattage bulbs or transformers to reduce the load. Otherwise use the dimmer elsewhere on a
suitable load.
The dimmer keeps turning itself off. The dimmer is doing this for 1 of 3 reasons: (1) It is overloaded. One solution
could be to use lower wattage bulbs or transformers to reduce the load. Otherwise use the dimmer elsewhere on a
suitable load; (2) There is a short-circuit. Check your wiring or consult a qualified electrician; (3) It is sensing an
unsuitable load such as a fan or wire-wound transformer. Either replace the transformer(s) with a dimmable electronic
transformer(s) or use the dimmer elsewhere on a suitable load.
