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.
