Installation
NB. For FRU units - go straight to point 6 below.
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 230Vac 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 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.
Set the rocker switch to WATER & HEATING. 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. Set the rocker switch to WATER ONLY. Press the
SELECT button until the bar in the display lines up
with the word ON and check that the water circuit only
operates.
12. 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.
13. Finally set time of day and programmes required,
noting that the unit is supplied with a pre-set
programme, as stated on Page 14.

(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
