Wall Timer Switches
Installation Information
Safety Warning
Before use please read carefully and use in accordance with these safety wiring instructions.
Before commencing any electrical work ensure the supply
is switched off at the mains
. Either by switching off the consumer unit or by removing the appropriate fuse.
Wiring should be in accordance with the latest edition of the IEE regulations (BS 7671).
Wire Identification – Twin & Earth Cable
EARTH
= Green/Yellow Sleeving
NEUTRAL
= Black (pre Apr 04) / Blue (after Apr 04)
LIVE
= Red (pre Apr 04) / Brown (after Apr 04)
To prevent fire hazard always use cable of the correct rating, size and type for the application.
Note
- If your installation uses a four lug metal mounting box, remove the top and bottom lugs or bend fully back.

Installation Instructions
The unit is designed to be used in place of a standard light switch in a one-way or two-way
standard circuit. Connections to other circuits are possible but beyond scope of this instruction,
so please consult a qualied electrician for advice. The rear face of the unit has a terminal block
with 3 connections:
If the Timer switch is required at the end of circuit without an existing Live connection, one of
the existing wires will need to be used to extent the Live connection to the unit.
Remove existing light switch & note the numbers of wires, excluding any Earth connections
& proceed as below:
For a one-way circuit there should be only 2 wires.
Typical One-Way Circuit
Connect
:
1. Live wire to the LIVE terminal.
2. Switched Live wire to the LOAD terminal
For a two-way circuit, depending on how it is wired, there may be either 3 wires at both
switches OR 3 wires at one switch & 5 wires at the other.
Typical Two-Way Circuit (3 Wires Both Ends)
Connect
:
1. Live wire to the LIVE terminal.
2. COM (or C) from other switch to LOAD terminal
3. L1 from other switch to 2-WAY terminal
4. Switched Live wire to the other switch COM terminal L2 on other switch has no connection,
& wire MUST be isolated by connecting to a seperate terminal block or similar.
This circuit normally uses 3-core insulated cable to connect between the COM, L1 & L2 ter-
minals between both switches. The end of the circuit with 5 wires also includes the Switched
LIVE & LIVE wires.
Typical Two-Way Circuit (5 Wires One End, 3 Wires Other)
Connect
:
1. Live wire to the LIVE terminal.
2. COM (or C) from other switch to LOAD terminal
3. L1 from other switch to 2-WAY terminal
4. Switched Live wire to LOAD terminal
L2 on other switch has no connection, & wire MUST be isolated by connecting to a separate
terminal block or similar.
NOTES
- The internal battery may require up to 2 hours to charge before first use, or long periods of non-use. To charge the unit must be connected to the mains power supply – and the switch turned
ON (under load conditions)
- Timer tol/- 2min per month
- Max load = 400W or 2.5 Amps
- Only suitable for most tungsten lament lamps
IMPORTANT
Do not use with fluorescent lighting, low energy CFL, low voltage
LIVE
: for connecting Live
LOAD
: for connecting switched live to Light bulb or Load
2-WAY
: for use with 2-way circuits only
Note
- It is important that a Live connection to the unit exists to provide permanent power for
the timer, especially on 2-way circuits where the Live connection will only be at one switch.
