5. Electrical connections are simplifi ed by using a Wiring
Centre. However, if this is not used, the wallplate terminal
identifi cation 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. 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 24-hour 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
SELECT/A/-
buttons all at the same time 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 fl 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.
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.
