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.
