What is a Programmer
A programmer allows you to set ON OFF time periods. Some models switch the 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.
