An explanation for householders
Programmers allow you to set ‘On’ and ‘Off’ time periods.
Some models switch the Central Heating and domestic Hot
Water on and off at the same time, while others allow the
domestic Hot Water and Central Heating to come on and go
off at different times. Set the ‘On’ and ‘Off’ time periods to
suit your own lifestyle.
On some programmers you must also set whether you want
the Central Heating and Hot Water to run continuously,
run under the chosen ‘On’ and ‘Off’ heating periods, or
be permanently off. The time on the programmer must
be correct. Some types have to be adjusted in Spring and
Autumn upon the changes between Winter and Summer time.
You may be able to temporarily adjust the heating
programme, for example, ‘Override’,‘Advance’ or ‘Boost’.
These are explained in the manufacturer’s instructions. The
Central Heating will not work if the room thermostat has
switched the Central Heating off. And, if you have a Hot
Water cylinder, the water heating will not work if the cylinder
thermostat detects that the Central Hot Water has reached
the correct temperature.
Introduction to the 1 Channel Programmer
This programmer can automatically switch your Central
Heating and Hot Water ON and OFF either 2 or 3 times a day,
at whatever times you choose. Timekeeping is maintained
through power interruptions by a replaceable internal battery
(by Qualified Installer/Electrician only) designed to last for

the lifetime of the programmer and 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 it if you want. During installation, 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 Settings (see installation
instructions).
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 5/2 Day programmer option allows different ON/OFF
times at weekends.
- The 7 Day programmer option allows different ON/OFF
times for each day of the week.
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 Factory Pre-Set Programme
This Channel Programmer has been designed to be simple
to use, requiring minimal user intervention with a pre-
programmed heating profile.
The pre-set heating times and temperatures will suit most
people (see table below). To accept the factory pre-set
settings, 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 button with a non
metallic pointed tool will return the unit to the factory-set
programme.
N.B. Every time the reset is pressed, the time and date must
be set again (page 15).
