...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.
