USER INSTRUCTIONS
3 CHANNEL PROGRAMMER
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 and
downstairs) 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 and 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 letter of the configuration (i.e. a U or an A) will be L if the Central Heating and Hot Water programmes
have been linked. In this mode the Hot Water and Central Heating 2 will run from the Central Heating 1
programme, so changes to the programme need only be made once and this will affect both Central Heating
channels and Hot Water.
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 then goes to RUN mode.
If the configuration setting on the rear DIP switch has been altered during the power
interruption the screen will initially show the new configuration. And the appropriate factory default programme
(see BUILT IN PROGRAMME section) will be installed. Press SET button to return to RUN mode.
