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 Central 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 Central 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 upon the changes between Winter and 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
Central Heating will not work if the room thermostat has
switched the Central Heating off. And, if you have a Hot
Water cylinder, the water heating will not work if the cylinder
thermostat detects that the Central Hot Water has reached
the correct temperature.
