OPERATING INSTRUCTIONS.

1.

Remove the setting pins and insert them at the times you wish
the switch to operate. ON = Inner Circle OFF = Outer Circle.
The shortest period is half-an-hour. Unused setting pins are
stored in the front of the unit.

2. Turn the programme ring clockwise, one complete turn, to
check the programme. Set the programme ring to the correct
time of day at the time indicator.

3. It is possible to manually override the programmed time by
operating the override switch in the right hand corner.
1 = ON. O = OFF.

Notes: a. The override switch cannot be used within 15 minutes
either side of a switching time.
b. Remember to reset the time following power failure.

This product must not be used on a load
greater than 3kW resistive.

Warning: Continuity of earthing must be maintained. If you have
any doubt about your ability to install this Timeswitch correctly
consult a competent electrician. The IEE Wiring Regulations
require that a means for disconnection from the supply having
a contact separation of at least 3mm in all poles must be
incorporated in the fixed wiring. Your consumer unit normally
complies. All conductors should be 1.5mm2 min.
