Installation Instructions

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.

Wallplate & Terminals

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.
