WHAT IS A CHANNEL PROGRAMMER?
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 2 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.
- Pumped System (PU) allows independent
control of Central Heating and Hot Water.
- Gravity System (GR) does not allow
Central Heating without Hot Water but can
provide Hot Water without Central Heating.
NB: When 5/2, 7 day or 24hr is selected for
HW then the same will be applied to Heating
and vise-versa.
IMPORTANT: This programmer is not suitable
for the switching of devices greater than 6
Amp rated. (e.g. Not suitable for use as an
immersion timer)
