What is a Channel Programmer?...
An explanaon for householders
On some programmers you must also set whether you want the
Central Heang and Hot Water to run connuously, run under the
chosen ‘On’ and ‘Off’ heang periods, or be permanently off. The
me on the programmer must be correct. Some types have to be
adjusted in Spring and Autumn upon the changes between Winter
and Summer me.
You may be able to temporarily adjust the heang programme, for
example, ‘Override’,‘Advance’ or ‘Boost’. These are explained in the
manufacturer’s instrucons. The Central Heang will not work if the
room thermostat has switched the Central Heang off. And, if you
have a Hot Water cylinder, the water heang will not work if the
cylinder thermostat detects that the Central Hot Water has reached
the correct temperature.
1
Programmers allow you to set ‘On’ and ‘Off’ me
periods. Some models switch the Central Heang and
domesc Hot Water on and off at the same me, while
others allow the domesc Hot Water and Central Heang to come
on and go off at different mes. Set the ‘On’ and ‘Off’ me periods
to suit your own lifestyle.

Introducon to the 2 Channel Programmer
This programmer can automacally switch your Central Heang or
Hot Water ON and OFF either 2 or 3 mes a day, at whatever mes
you choose. Timekeeping is maintained through power interrup-
ons by a replaceable internal baery (by Qualified Installer/Electri-
cian only) designed to last for the lifeme of the programmer and
the clock is automacally 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 me and date, but you
can alter it if you want. During installaon, the installer selects 24
hour, 5/2 day, or 7 day programming and either 2 or 3 on/off
periods per day, via the Technical Sengs (see installaon instruc-
ons).
The large, easy to read display makes programming easy and the
unit is designed to eliminate the possibility of accidental changes to
your programme. Buons normally visible, only affect your set
programme temporarily. All buons which can permanently change
your programme are located behind the flip over facia.
- The 24 hour programmer opon runs the same programme every
day.
- The 5/2 Day programmer opon allows different ON/OFF mes at
weekends.
- The 7 Day programmer opon allows different ON/OFF mes for
each day of the week.
- Pumped System (PU) allows independent control of Central
Heang and Hot Water.
- Gravity System (Gr) does not allow Central Heang without Hot
Water but can provide Hot Water without Central Heang.
IMPORTANT: These sengs should only be changed by a qualified
person. Contact your installer. This programmer is not suitable for
the switching of devices greater than 6Amp rated. (e.g. Not suitable
for use as an immersion mer)

Programming the Unit
The Factory Pre-Set Programme
This Channel Programmer has been designed to be simple to use,
requiring minimal user intervenon with a pre-programmed heang
profile.
The pre-set heang mes and temperatures will suit most people
(see table below). To accept the factory pre-set sengs, move the
slider to RUN which will revert the programmer to Run Mode (the
colon (:) in the LCD display will begin to flash).
If the user changes from the factory-set programme and wants to
return to it, pressing the reset buon with a non metallic pointed
tool will return the unit to the factory-set programme. NB. Every
me the reset is pressed, the me and date must be set again (page
10).

Basic Sengs
Seng the Time and Date
The me and date are factory set and changes between summer
and winter me are handled automacally by the unit.
1. Switch the slider to Time/Date.
2. The hour symbols will flash, use the +/- buons to adjust.

down.
4. Once the countdown has finished, the programmer will return
to normal operaon. It may be advisable to set the Holiday Mode
1 day less so the house is back up to temperature for your return.
5. To cancel the Holiday Mode, press the buon to revert back
to run mode.

Reseng the Unit
Press the reset buon with a non-metallic pointed tool to reset the
unit. This will restore the built in programme and also reset the me
to 12:00pm and the date to 01/01/2000. To set the me and date,
please refer to page 10.
NB: As a safety feature aer reseng the unit will be in OFF operat-
ing mode. Reselect your required operang mode (page 6). Use of
excessive force may result in the reset buon scking behind the
front cover of the programmer. If this happens the unit will “freeze”
and the buon can only be released by a qualified installer.
11
Power Interupon
In the event of a mains supply failure the screen will go blank but the
back-up baery ensures that the programmer connues to keep the
me and retain your stored programme. When power is restored,
switch the slider to RUN to return to Run mode.
Seng the Backlight
The backlight can either be set permanently ON or OFF. The
programmer backlight is pre-set to be permanently OFF. When the
backlight is permanently OFF, the backlight will turn ON for 15
seconds when + or – buon is pressed, then turn OFF automacally.
To change seng to permanently ON, move the slider to TIME/-
DATE. Press the Next buon repeatedly unl Lit is displayed.
Press +/- to turn backlight ON or OFF. Press the Next buon or
wait for 15 seconds to automacally confirm and return to Run
Mode.
NB: Do not use Advance or +HR Boost Buon to acvate the
backlight as it may engage the Advance or +HR facility and turn on
the boiler. Only use the Home buon.

Installaon Safety Instrucons
The unit must be installed by a suitably qualified person in accord-
ance with the latest IEE Wiring Regulaons.
Isolate mains supply before commencing installaon. Please read all
instrucons before proceeding.
Ensure that the fixed wiring connecons to the mains supply is via a
fuse rated at not more than 6 amps and class ‘A’ switch having a
contact separaon of a minimum of 3mm in all poles. The recom-
mended cable sizes are 1.0mm sqr or 1.5mm sqr.
No earth connecon is required as the product is double insulated
but ensure connuity of earth throughout the system.
If the unit is fied to a metal surface, IT IS ESSENTIAL that the metal
be earthed. DO NOT use a surface mounng box.
NEVER fit or remove the unit to a live wall-plate.
Maintenance
Always isolate the mains supply before commencing any work,
servicing or maintenance on the system. And please read all instruc-
ons before proceeding.
Arrange for an annual maintenance and inspecon schedule to be
carried out by a qualified person on every part of the heang and hot
water system.
WARNING!
ALWAYS ISOLATE THE AC MAINS SUPPLY BEFORE INSTALLING.
THIS PRODUCT MUST BE FITTED BY A QUALIFIED PERSON, AND
INSTALLATION MUST COMPLY WITH THE GUIDANCE PROVIDED IN
THE CURRENT EDITIONS OF BS767 (IEE WIRING REGULATIONS) AND
PART “P” OF THE BUILDING REGULATIONS.

Technical Sengs
1. Move the slider to RUN. Hold down the Home buon, the Day
buon and the buon (under the facia) together for 3 seconds
to enter the Technical Seng Mode.
2. Press +/- to choose between 2 or 3 ON/OFFs per day.
3. Press the Next buon and press +/- to choose between Pu
(Pumped, allows independent control of CH and HW) or Gr (Gravity,
does not allow CH without HW but can provide HW without CH).
4. Press the Next buon and press +/- to choose between
Protecon ON/OFF. (If Protecon is ON and the system does not call
for heat for one week, the system will be turned ON for one minute
each week that the system does not call for heat.)
5. Press the Next buon and press +/- to choose between 12
hour clock or 24 hour clock.
Fing the Back Plate
1. Posion the wall-plate (terminals along top edge) with 60mm
(min) clearance to its right, 25mm (min) above, 90mm (min) below.
Ensure that the supporng surface will fully cover the back of the
programmer.
2. Offer the back plate to the wall in the posion where the
programmer is to be mounted, remembering that the back plate
fits to the le side of the programmer. Mark the fixing posions
through the slots in the back plate, drill and plug wall, then secure
back plate in posion.
3. All necessary electrical connecons 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.
