New Installations
Example circuit diagrams for typical installations are show below. These diagrams are
schematic and should be used as a guide only.
Please ensure that all installations comply with the current IEE regulations.
For reasons of space and clarity not every system has been included and the diagrams have
been simplied, for instance some Earth connections have been omitted.
Other control components shown in the diagrams i.e. Valves, RoomStats etc are general
representations only. However the wiring detail can be applied to the corresponding models of
most manufacturers e.g. Horstmann, Honeywell, Danfoss Randall, Drayton etc.

C=Common Call = Call for heat or break on rise SAT = Satiseld on rise N= Neutral
Existing Installations
1. Remove old programmer from its back plate mounting loosening any securing screws as
dictated by its design.
2. Check compatibility of existing back plate & wiring arrangement with that of the new
programmer. See online Programmer Compatibility Guide for direction.
3. Make all necessary changes to back plate & wiring arrangement to suit new
programmer
Installation Safety Notes
This unit must be installed by a suitably qualied person in accordance with the latest IEE
Wiring Regulations.
Isolate mains supply before commencing installation. Please read all installation
instructions before proceeding.
Ensure that the xed wiring connections to the mains supply is via a fuse rated at not more
than 6 amps and a class ‘A’ switch having a contact separation of a minimum of 3mm in all
poles. The recommended cable sizes are 1.0mm2 or 1.5mm2
If the unit is tted to a metal surface, IT IS ESSENTIAL that the metal be earthed.
DO NOT use a surface mounting box.
No earth connection is required as the product is double insulated but ensure continuity of
earth throughout the system.
NEVER t or remove the unit to a live wall-plate.
Fitting Back Plate – Direct Wall Mounting
1. Position the wall-plate (terminals along top edge) with 60mm (min) clearance to its right,
25mm (min) above, 90mm (min) below. Ensure that the supporting surface will fully cover
the back of the programmer.
2. The ideal location would be 1.4M above oor level, easily accessible, reasonably lit and
free from condensation or temperature extremes.
3. Offer the back plate to the wall in the position where the programmer is to be mounted
remembering that the back plate ts to the left hand end of the programmer. Mark the xing
positions through the slots in the backplate, drill and plug wall, then secure back plate in
position using screws.
4. All necessary electrical connections should now be made. Ensure that the wiring to the
wall-plate terminals leads directly away from the terminals and is completely
enclosed within the wall-plate aperture. Wire ends must be stripped and screwed to
the terminals so that minimal bare wire is showing.
Fitting Back Plate – Wiring Box Mounting
1. Fix the wall-plate to a ush mounting single conduit box type UA1 (BS4662) using M3.5 x
14 screws. Take care to ensure the opening is adequate and will allow mounting of the unit
onto the base plate. The use of glue, mastic, or other sealants MUST NOT be used to secure
the unit to the wall.
2. All necessary electrical connections should now be made. Ensure that the wiring to the
wall-plate terminals leads directly away from the terminals and is completely enclosed within
the wall-plate aperture. Wire ends must be stripped and screwed to the terminals so that
minimal bare wire is showing.

USER INSTRUCTIONS
1 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.
If this happens simply press +HR button (2) 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 then goes to RUN mode.
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.

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 qualied 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 ip-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

“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.

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 RUN mode if a period of 5 minutes passes without any but-
tons 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 01/01/2000. 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 after reset the unit will be in OFF operating mode. Reselect your required
operating mode,
NOTE: Use of excessive force may result in the reset button sticking behind the front
cover of the programmer. If this happens the unit will “freeze” - and the button can
only be released by a qualied installer MODE
