Installation Instructions

Installation

NB. For FRU units - go straight to point 6 below.

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.

Wallplate & Terminals

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 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 ap 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. 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 xing 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.
