What is a 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 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 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 at the changes
between Greenwich Mean Time and British Summer Time.
You may be able to temporarily adjust the heating pro-
gramme, for example, ‘Override’, ‘Advance’ or ‘Boost’. These
are explained in the manufacturer’s instructions.
The heating will not work if the room thermostat has switched
the heating off. And, if you have a hot-water cylinder, the
water heating will not work if the cylinder thermostat detects
that the hot water has reached the correct temperature.

If the engineer has set your program and timings – you won’t
need to do anything else. Just keep this guide in a safe place
for future reference.
Sometimes you might need to change the way you use your
system temporarily – perhaps due to an exceptionally cold day.
Here’s how to do it – without affecting the timings in your
program.
Switching on and off
On the front of the timeswitch there is an
button.
It allows you to switch your system either on or off, irrespective of
the program. So if the heating is off, and you want warmth now,
you can either –
1. Press
Advance
to switch it on (ADV will be displayed), and it will
stay on until the end of the next period. Or if the heating is on and
you don’t need it, press Advance and it will go off until the
beginning of the next ON period.
Advance will only operate in TIMED or ONCE modes.
2. Press & Hold
to switch on for an extra hour ( & BST will
be displayed), then Press again for two ( ) or three ( ) hours.
To cancel Boost, Press Boost again ( ). Or if the heating is
already on, using Boost will extend the ON time by one, two or
three hours.
DAY-TO-DAY VARIATIONS

= continuously on.
Use the SELECT button under the flap to change the
mode.
This won’t alter the timings in your program, which you
can return to by selecting TIMED.
