4. Programming the
time switch:
a) Decide what times you would like the time switch
to switch ON and OFF.
b) Push the required segments down for the duration
of an ON period, and pull them up for the duration
of an OFF period. The minimum switching interval
is 15 minutes, and this can be increased in
15 minute steps.
c) Set the correct time, by rotating the dial clockwise
until the correct time is indicated by the triangular
pointer. Note that as the dial is rotated there will
be an increased resistance to turning as ON/OFF
periods are passed.
Points to note:
The segment dial can be turned whilst the time
3
controller is operating.
In case of power failure, re-adjust the time controller
to the correct time of day by turning the dial in
a clockwise direction until the correct time is
indicated by the pointer.
5. Permanent Override:
The main slider on the timer can be set to permanent
on by sliding it to the left, aligning the arrow head
to the 1 symbol.
In the middle position, with the arrow head pointing
at the timer symbol, the timer is in automatic mode.
If the slider is moved to the right, and the arrow head
points at the 0 symbol, the timer is permanently OFF.
