1.1 General energy information
What is a programmer?...an Explanation for Householders
(as recommended by the Energy Savings Trust)
Programmers allow you to set ‘ON’ and ‘O ’ 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 ‘O ’ 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 ‘O ’ 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.

and O periods to suit your own lifestyle.
