RESET
Should the unit be disconnected from the mains a small battery
symbol will blink on the left hand side of the display. After the second
midnight, i.e. between 24 and 48 hours, the display will go blank and
the unit will lose its settings. When mains power is restored it is
recommended that the unit be reset by lowering the front flap and
using a small non-metallic object, e.g. matchstick, press and release
the recessed reset button (marked R/S). This installs the factory pre-
set programme and sets the time to 12:00pm on Monday (MO). The
outputs will be OFF, (see Fig. 1). Note that the colon between the hours
and minutes is blinking. This means the unit is in RUN mode and will
switch the Central Heating and Hot Water on and off in accordance
with the programme. The colon only blinks in RUN mode.
CHOICE OF 12 HR OR 24 HR CLOCK
At any time during RUN mode the time displayed can be toggled

seconds.
