PROGRAMMER SUMMARY
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 non-replaceable 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/off 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 qualified person. Contact
your installer.
IMPORTANT:
This programmer is not suitable for the switching of devices greater
than 6Amp rated. (eg. Not suitable for use as an immersion timer)
The large, easy to read display makes programming easy and the unit is designed to
eliminate the possibility of accidental changes to your programme. Buttons normally
visible only affect your set programme temporarily. All buttons which can permanently
change your programme are located behind the flip-over facia.
- The 24 hour programmer option runs the same programme every day.
- The 5 day/2 day programmer option allows different ON/OFF times at week ends.
- The 7 day programmer option allows different ON/OFF times for each day of the
week

USING ADVANCE
The ADVANCE function allows the user to move to the next ON or OFF programme for a
“one off” event, without having to change the programme or use the ON or OFF
buttons.
Warning:
The ADVANCE function is only available when programme is in AUTO or ALL
DAY operating modes.
To advance Central Heating
Press the ADV (1) 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(1) button is
pressed again, or until a programmed ON/OFF period commences. The word ADV will
appear in the top left hand corner of the LCD.
USING THE +HR BOOST
Press the +HR button (2) to make the desired selection with one, two or three hours
extra heating 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.
NOTE:
If the programmer is in the OFF mode and then +HR button (2) 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.
