Installation
NB. For FRU units - go straight to point 6.
1. Loosen the xing screw in the base of the unit to release the
Wiring Cover.
2. Holding the unit face downwards, press rmly in the
centre of the wallplate and slide it apart and lift it from the
module.
3. Fix the wallplate and terminal block to the wall, or plaster
box, as required. Ensure that the screw heads do not
protrude beyond the vertical centre rib of the wallplate,
or this will prevent the module correctly locating onto the
wallplate.
4. Surface cables can only enter from below the unit. Cut
an appropriate cable aperture in the wiring cover. If the
wallplate is mounted on a plaster box, cables can enter
from the rear below the terminal block.

5. Electrical connections are simplied by using a Wiring
Centre. However, if this is not used, the wallplate terminal
identication is as shown.
If the system being controlled is 230 Vac then terminals
3 and L must be linked with insulated cable capable of
carrying full load current. Whilst the unit does not require
an earth connection, a terminal is provided on the wallplate
for earth continuity purposes.
6. Referring to the wiring diagrams on page 6-9, connect the
unit as shown.
7. Find out from the user whether the unit is required to
operate in 24-hour mode (factory preset) or weekday/
weekend mode (5/2 day). To convert to 5/2 day mode
remove the small two-way connector from the pins towards
the left of the recess on the rear of the module, then press
the SELECT/ADVANCE/+/- buttons all at the same time to
RESET the unit.
8. Ensure all dust and debris are cleared from the area. Plug
the module into the wallplate by locating it onto the
wallplate and, when ush with it, sliding it down, ensure
the hook at the top of the wallplate engages with the slot
at the back of the module.
9. Before setting the programme, check the unit and circuit.
Press the SELECT button until the bar in the display lines up
with the word ON. Adjust the remote thermostats to check
the system operates correctly.

10. Then press the SELECT button until the bar lines up with
the word OFF and check the system does not operate.
11. When the circuit check has been completed, replace the
wiring cover and tighten the xing screw. Cut any cable
aperture in the wiring cover which may be necessary to
accommodate surface mounted cables.
12. Finally set time of day and programmes required, noting
that the unit is supplied with a pre-set programme, as
stated on Page 14.

What is a programmer?
... an explanation for householders.
Programmers allow you to set ‘On’ and ‘O’ time periods.
Some models switch the central heating and domestic hot
water on and o at the same time, while others allow the
domestic hot water and heating to come on and go o at
dierent times.
Set the ‘On’ and ‘O’ time periods to suit your own lifestyle.
On some programmers you must also set whether you want
the heating and hot water to run continuously, run under the
chosen ‘On’ and ‘O’ heating periods, or be permanently o.
The time on the programmer must be correct. Some types
have to be adjusted in spring and autumn at the changes
between Greenwich Mean Time and British Summer Time.
You may be able to temporarily adjust the heating
programme, for example,‘Override’,‘Advance’or‘Boost’. These
are explained in the manufacturer’s instructions.
The heating will not work if the room thermostat has switched
the heating o. And, if you have a hot-water cylinder, the
water heating will not work if the cylinder thermostat detects
that the hot water has reached the correct temperature.
The text below has been edited and approved by the Plain
English Campaign, who has issued a Crystal Mark to be
displayed with it.
What is a programmer?
Please note: A timeswitch is a single channel programmer. It will
allow you to set your system’s On and O periods.

User Instructions
Your timeswitch
Your 103E5 timeswitch controls your hot water and heating

The 103E5 can provide 3 ON periods and 3 OFF periods each day
and can oer either 24 hour control (same programme for each
day of the week) or 5/2 day control (one set of programmes for
weekdays and a dierent set for weekends)

Battery backup
In the event of a power cut, the built-in lithium battery will
keep your time and programme settings for up to 15 days.
After 15 days without mains power the unit will switch o
