Information about the device
What is a programmer?
Savings Trust)
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
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.
