Introduction

This programmer can automatically switch your
central heating or hot water ON and OFF up to 3 times
a day, at whatever times you choose. Timekeeping is
maintained through power interruptions by a non­replaceable battery designed to last for the lifetime
of the programmer. The clock is automatically put
forward 1 hour at 1:00am on the last Sunday of March
and back 1 hour at 2:00am on the last Sunday of
October. The clock is factory pre-set to UK time and
date, but you can alter the time setting if you wish.

During installation, the installer selects 24 hour, or
5 day/2day, or 7 day programming and 2 or 3 on/o
periods per day, via a 4 position DIP switch on the
back of the unit (see installation instructions).

IMPORTANT: These settings should only be
changed by a qualied person. Contact your
installer.

IMPORTANT: This programmer is not suitable
for the switching of devices greater than 2 Amp
rated per channel. (e.g. Not suitable for use as an
immersion timer)

Conguration

When setting time, date or changing programme
times the rst screen displayed indicates the
conguration as set up by the installer. (See ‘Setting
The Time section)

The 24 hour, or 5 day/2day, or 7 day programming
option as set up by the installer can also be veried
at this stage by how the Monday to Sunday indicators
are displayed.

Built In Programme

For convenience, the programmer has a built in
programme which will be satisfactory for many
people, but which can be changed very easily (see
section CHANGING PROGRAMME TIMES). Once the
unit is powered up this built in programme will run.

If the user changes from the built in programme and
wishes to return to it, then pressing the reset button
with a non metallic pointed tool will return the unit
to the built in / default programme

.

NOTE: Every time the reset is pressed, the time
and date must be set again. See the sections

‘Setting The Time & Setting The Date’

Programming Notes

The unit will automatically return to normal running
if a period of 30 seconds passes without any buttons
being pressed.

For convenience, to allow for programmes to go past
midnight, the programme day is from 03:00am to
02:50am the next day.

If a programme is required to run from 1.00 am to

8.00 am then 2 programmes must be used because it
is not possible to programme through 2.50 am. (The
programme should be split up into two sections; 3.00
am > 8.00 am and 1.00 am > 2.50 am).

Reset

Press the reset button with a non-metallic pointed
tool to restore the built in programme. As well as
restoring the built in programme, it also resets the
time to 12:00pm and the date to 01/01/2014. Initially
the display shows all segments lit for a few seconds,
but then will show the current conguration. See
SETTING THE TIME section to continue.

As a safety feature aer reset the unit will be in OFF
operating mode. Reselect your required operating

mode.

Using Advance

The ADVANCE function allows the user to move
to the next ON or OFF programme for a “one o”
event, without having to change the programme or
operating mode.

Warning: The ADVANCE function is only available
when programme is in AUTO or ALL DAY operating

modes.

To advance Central Heating

Press the ADV button. This will turn the Central
heating ON if it is in an OFF period and OFF if it is
in an ON period. It will stay in this state until either
ADV button is pressed again, or until a programmed
ON/OFF period commences. The word ADV [5] will
appear in the top le hand corner of the LCD.

Using +HR Boost

Press the +HR button to make the desired selection with
one, two or three hours extra heating [6] and cancel

options offered.

Warning: The +HOUR function is only available when
programme is in AUTO , ALL DAY or OFF operating modes.

If the Central heating operating mode is OFF, then it will
switch on for the extra hours selected. If the Central
heating mode is AUTO or ALL DAY, then during an OFF
period, it will switch on for the extra hours selected.
If during an ON period, then it will temporarily extend
that programme by the number of hours selected, this is
displayed on the right of the LCD display [6].

NOTE: If the programmer is in the OFF mode and then
+HR button is pressed (+1 HR, + 2 HR, or + 3 HR) and

the resulting time of the boost overlaps a START / ON time
in the AUTO mode programme memory then the boost will
disengage. If this happens simply press +HR button again
and the boost will activate for the time period chosen.

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 returns to its expected operating
condition.

If the conguration setting on the rear DIP switch
has been altered during the power interruption the
screen will initially show the new conguration. And
the appropriate factory default programme (see
BUILT IN PROGRAMME section) will be installed.
Press SET button to return to RUN mode.
