What is a Channel Programmer?...
An explanaon for householders
On some programmers you must also set whether you want the
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 heang will not work if the room
thermostat has switched the 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 Heang to come on and
go off at different mes. Set the ‘On’ and ‘Off’ me periods to suit
your own lifestyle.

An explanaon for householders
Introducon to the 1 Channel Programmer
This programmer can automacally switch your Central Heang or
Hot Water ON and OFF up to 3 mes a day, at whatever mes you
choose. Timekeeping is maintained through power interrupons
by a non replaceable baery 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 wish. During installaon, 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 posion DIP switch on the back
of the unit (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.
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)

The Factory-Set Programme
This is the factory-set programme built into the unit. If the user
changes from the factory-set programme and wishes 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 8).
If the unit is installed as a 24 hour programmer the built in
programme will be the same for each day (i.e. Sat-Sun be same as
Mon-Fri above).
Changing The Programme (refer to Fig.1, Page 4)
For 7 Day Programmer Opon - the inial programme displayed will
be for Monday. You can go to any day of the week by pressing the
DAY buon repeatedly. The COPY buon will copy the current
programme onto the next day. NB. It is not possible to copy Sunday
to Monday.
For 5/2 Day Programmer Opon - the inial programme displayed
will be for Monday - Friday. Press the DAY buon for Saturday -
Sunday programme. The COPY buon will copy the current
programme onto the next day group. NB. It is not possible to copy
Saturday-Sunday programme to Monday-Friday programme.
For 24 Hour Programmer Opon - the built in programme will be
the same for each day. The COPY & DAY buons have no effect if
installed as a 24 hour programmer.
