recommended that the time switch be installed
with the base provided.

4. Terminals are for xed wiring only.
Provision must be made in the xed wiring

for a means of disconnection from the supply
having a contact separation of at least 3mm
on all poles.

5. This product is suitable for ‘Ordinary’

screws for xing so screw heads sit ush

inside base.

intended.
c. When mounting the time switch on a
metal surface, ensure the metal is adequately
earthed to cover the 20A rating in accordance
with IEE Regulations.

satisfactory connection with terminals.
Connect switch to supply and load as in wiring
diagrams above.

Programming the Time Switch

There is standard ‘On’ period from 7.00 am to 5.00 pm, Mon-Sun
memorised into the product. Programming the time switch to a time
other than that is achieved by ‘painting in’ or ‘wiping out’ ‘On’
markers as the analogue hand is moved around the 24-hour clock
display in either direction using the + or - buttons.

Notes: Press Set Prog as required to skip to required day.
Pressing Set prog memorises a days program.
Analogue hand starting point is 0:00 LED ashing indicates
programming neutral mode.
Press + or – to reach the time you require before programming.
Press set ON or set OFF twice will bring unit back to programming
neutral mode.
Programming is in 15 minute increments as viewed on the Digital
display; 15, 30, 45, 00.
The Analogue display segment resolution is 30 minutes.

So program periods at 15 or 30 = one segment, 45 or 00 = next

segment.

The unit can be reset back to the default settings simply by pressing
the + and - keys simultaneously until the full display occurs.
Continue pressing + and - keys and press set clock, revu & copy to
