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.
INTRODUCTION
This central heating programmer can automatically switch your central heating and hot
water ON and OFF, independently, up to 3 times a day, at whatever times you choose.
