USER INSTRUCTIONS
General notes on using the programmer
The programmer automatically controls the
times at which your boiler operates to provide
heating and hot water. It also provides a
permanent display of the time of day (24 hr or
am/pm display) and day of the week. Indicators
on the display show when both the hot water
(indicated by a tap symbol) and heating
(indicated by a radiator symbol) is either ON or
OFF.
If the electricity supply to the boiler is
interrupted, e.g. during a power cut, the display
will remain and the programmer will retain the
time and on/off program settings. It will not
have to be reset when the supply is restored.
The programmer is supplied with three pre-set
program options each giving different On/Off
settings. Refer to page 3 –
To select and use a
pre-set program
. Please note that these pre-
set programs will switch
both
heating and hot
water ON and OFF at the
same
times.
Alternatively, you can set your own program of
On/Off settings, with different ON and OFF
times for heating and Hot water as you require.
Different On/Off settings for different days of the
week can also be set. You can set up to 10 ON
and 10 OFF commands throughout the week.
Refer to page 5 –
Setting your own program
.
Once set this program can be changed at any
time as required.
When setting the times for the ON periods it is
useful to remember that it might take up to an

hour for the house to become warm, especially
in colder weather. Also the effect of the central
heating will remain for a time when the central
heating is turned off.
A hot water cylinder may take ½ hour or more
to heat up fully. A well insulated cylinder will
retain its heat for quite some time after the
boiler is turned off.
When setting the time for the start of the first
ON period it must be after midnight. The time
for the end of the last ON period can be after
midnight. Refer page 6 - for the '
Shift'
function
section.
While setting any times, if a period of more than
1 minute elapses since the last key was
pressed, the programmer automatically reverts
back to the original program. Any changes
made up to that point will be lost as they were
not confirmed.
To temporarily override the current switching
time, i.e. change OFF to ON or ON to OFF, use
the
‘+’
and
‘-’
keys on the programmer.
Pressing the
‘+’
key will advance the Heating to
the next program operation and the
‘-’
key will
do the same for the Hot Water.
NB. The programmer will NOT automatically
return to the set program at the start of the
next program operation. Refer to Page 6 - To
manually override automatic operation.
For ‘Summer’ use the central heating can be
set to OFF by pressing the
‘+’
key. Check that
the ‘switching status’ display indicates that
the heating function is OFF.
