An automatic time switch can turn the heating on and off at pre-set times
to suit your pattern of everyday life. This is an inexpensive way of
controlling your heating system.
Time switches can also plugged in at the wall, to allow equipment or lights
to switch on and off at pre-set times. This is a useful security step to
take and can also make a warm welcome when returning home late at night.
Remember to occasionally change the settings from time to time, to avoid an
obvious pattern of lighting seen from outside.
