Your timeswitch
Your 103 timeswitch has one time output which can be used to
control your heating and hot water at the same times.
Normally the 103 provides 2 ON periods and 2 OFF periods each
day. However 1 ON and 1 OFF period can be obtained by using
the Pre-Selector Wheel (see page 12).
You can choose whether the 103 controls your hot water & heating
at the programmed times, constantly ON or constantly OFF.
