Danfoss Heating

What is a programmer?

... 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 diﬀ erent 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.
