Introduction

What is a central heating programmer...?
Central Heating programmers allow you to set 'On'
and 'Off' time periods for your heating and/or hot
water. One Channel models switch your central heating
and domestic hot water on and off at the same time,
while the two and three channel versions control your
domestic hot water and heating to come on and go
off at different times. Three channel programmers
are often used to provide separate control for two
heating zones (perhaps upstairs
as well as the separate control for your hot water.
Sangamo Choice programmers make it easy to set the
'On' and 'Off' time periods to suit your own lifestyle, with
options for; 7 day, 5/2 day, and 24 hour programming.
You can also choose to have your heating and hot water on
continuously or be permanently off. Choice programmers
also adjust automatically between Greenwich Mean Time
and British Summer Time. The Choice programmers even
have a default set of programmes, so you can decide
not to adjust the programming at all! And to improve
your comfort, you can temporarily adjust the heating
programme, with the Choice; 'Advance' or 'Boost' buttons.

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.
(e.g. 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 ac-
cidental 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 fascia.
• The 24 hour programmer option runs the same
programme every day.
• The 5 day/2 day programmer option allows differ-
ent ON/OFF times at week ends.
• The 7 day programmer option allows different ON/
OFF times for each day of the week
