Installation
NB. For FRU units - go straight to point 6.
1. Loosen the fixing screw in the base of the unit to release the
Wiring Cover.
2. Holding the unit face downwards, press firmly 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 simplified by using a Wiring
Centre. However, if this is not used, the wallplate terminal
identification 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. Refer 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 7-day 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 button marked R/S under the flap 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 flush 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 fixing 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 15.

What is a programmer?
... an explanation for householders.
Programmers allow you to set ‘On’ and ‘Off’ time periods.
Some models switch the central heating and domestic hot
water on and off at the same time, while others allow the
domestic hot water and heating to come on and go off at
different times.
Set the ‘On’ and ‘Off’ 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 ‘Off’ heating periods, or be permanently off.
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 off. 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.
Please note: A timeswitch is a single channel programmer. It will
allow you to set your system’s On and Off periods.

Setting the Day
The day of the week is set automatically.
Factory Presets
The unit is supplied with the following preset programme which
will be active after the unit has been reset.
Mon-Fri Sat-Sun
1st ON 6.30am 7.30am
1st OFF 8.30am 10.00am
2nd ON 12.00pm 12.00pm
2nd OFF 12.00pm 12.00pm
3rd ON 5.00pm 5.00pm
3rd OFF 10.30pm 10.30pm
NB. 2nd ON and 2nd OFF are set to the same time. These 2 times
are ignored by the programme therefore the heating will just
come on once in the morning and once in the evening. If you
want the heating to come on in the middle of the day set the
2nd ON and 2nd OFF to the times you require.
Accepting the preset times
If you are happy to use the settings
above, you don’t need to do anything
else.
To accept the presets press the PROGRAMME button until the
colon in the display begins to flash.
Your unit is now in RUN mode.

16
Changing the preset programmes
Your installer will have set your unit to operate in one of the
following modes:
7 day - different settings for each day of the week
(page 16-17) - default setting.
5/2 day - one set of programmes for weekdays and another
for weekends (page 18-19) .
Please follow the correct instructions to programme your unit.
Please Note
The unit must be programmed in sequence and ON/OFF
times cannot be set out of sequence.
If you want to leave a preset time as it is, simply press NEXT
ON/OFF to move on to the next setting.
Your clock will allow you to programme 3 ON/OFF settings
per day. If you do not wish to use one of the ON/OFF
settings, simply programme the ON time to be the same as
the OFF time and the setting will not operate.
If at any time you get confused and need to reset your
timings to the standard preset programme, press the R/S
button to return to the preset programmes.
