Service Interval Timer
... 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 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.
What is a programmer?
Please Note:
Please note: A timeswitch is a single channel programmer. It will allow you to set your system’s On and Off periods.
