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 programme,
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.
The text below has been edited and approved by the
Plain English Campaign, who has issued a Crystal Mark
to be displayed with it.

1.1 Your Programmer
The FP715 Si allows you to switch your heating and hot water on and
off at times that suit you.
Your programmer has had the date and time set up during
manufacture and will automatically change between Greenwich
Mean Time and British Summer Time.
You can programme up to 3 ON/OFF times per day for the heating and
the hot water and the two systems can be operated independently.
1.2 Preset Programmes
Your FP715 Si comes ready programmed with a set of operating
times which often suit most people.
If you want to change any of these settings, you can do so by
following the instructions on pages 9-14. First, follow the steps on
page 7-8 to set the correct time and date.

1.7 Before you change the preset programmes
Your installer will have set your unit to operate in one of the following
modes:
