Reseng the Unit

Press the reset buon with a non-metallic pointed tool to reset the

unit. This will restore the built in programme and also reset the me

to 12:00pm and the date to 01/01/2000. To set the me and date,

please refer to page 10.

NB: As a safety feature aer reseng the unit will be in OFF operat-

ing mode. Reselect your required operang mode (page 6). Use of

excessive force may result in the reset buon scking behind the

front cover of the programmer. If this happens the unit will “freeze”

and the buon can only be released by a qualiﬁed installer.

Power Interupon

In the event of a mains supply failure the screen will go blank but the

back-up baery ensures that the programmer connues to keep the

me and retain your stored programme. When power is restored,

switch the slider to RUN to return to Run mode.

Seng the Backlight

The backlight can either be set permanently ON or OFF. The

programmer backlight is pre-set to be permanently OFF. When the

backlight is permanently OFF, the backlight will turn ON for 15

seconds when + or – buon is pressed, then turn OFF automacally.

To change seng to permanently ON, move the slider to TIME/-

DATE. Press the Next buon repeatedly unl Lit is displayed.

Press +/- to turn backlight ON or OFF. Press the Next buon or

wait for 15 seconds to automacally conﬁrm and return to Run

Mode.

NB: Do not use Advance or +HR Boost Buon to acvate the

backlight as it may engage the Advance or +HR facility and turn on

the boiler. Only use the Home buon.
