Resetting the Unit
Press the reset button with a non-metallic pointed tool to reset the
unit. This will restore the built in programme and also reset the time
to 12:00pm and the date to 01/01/2000. Initially the display shows
all segments lit for a few seconds, but then will show the current
configuration. To set the time and date, please refer to page 8.
NB: As a safety feature after resetting the unit will be in OFF operat-
ing mode. Reselect your required operating mode (page 5). Use of
excessive force may result in the reset button sticking behind the
front cover of the programmer. If this happens the unit will “freeze”
and the button can only be released by a qualified installer.

Setting 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 – button is pressed, then turn OFF automatically.
To change setting to permanently ON, press SET repeatedly until L
IR is displayed. Press + or – to turn backlight ON or OFF. Press SET to
confirm.
NB: Do not use Advance or +HR Boost Button to activate the
backlight as it may engage the Advance or +HR facility and turn on
the boiler. Only use + or - button under facia cover.

Power Interruption
In the event of a mains supply failure the screen will go blank but the
back-up battery ensures that the programmer continues to keep the
time and retain your stored programme. When power is restored, if
there has been no change to the rear DIP switch, the programmer
then goes to RUN mode. If the configuration setting on the rear DIP
switch has been altered during the power interruption the screen
will initially show the new configuration and the appropriate factory
default programme will be installed. Press SET button to return to
RUN mode.
