This unit should be installed by a

the current IEE Wiring Regulations.
If in doubt consult a qualified electrician.
• Before connecting the timer to the
mains, check that the mains
voltage and frequency correspond to
the rating plate (on side of timer).
• Do not overload. Refer to the
Ampere rating (amps) on the
rating plate.
• Do not expose the timer to
extremely high or low
temperatures. Do not place the timer
in direct sunlight.
• Do not allow the timer to come
into contact with water.
• If the time switch is mounted near
equipment where heat produced raises
the local ambient temperature above
55°C, then a 1/2 module space should be
left between the time switch and the
equipment.
• If used to operate a contactor, then a 1
module space should be left between
timer and contactor.
You can set as many as six switching-on
commands and an equal number of
corresponding switching-off commands
in the following manner:
1) Depress “Timer” button
once. The actual time will
disappear from the display.
This Timer on indication
will be displayed instead,
denoting a vacant “on”
time on No. 1 programme.
NOTE: Setting hours and minutes: When
setting switch-on time and switch-off time be
sure to set minutes as well as hours.
E.g. if 08.00 is required set all
4 digits: “08.”
and
“.00”
2)Set the required switching-on time
using button “h+” and “m+”.
3)Set the day(s). See “Day” button
selection (over) on which the
switching-on command must be
executed.
• This timer is designed to be din rail
mounted.
• Ensure that the 230V AC supply is
connected to terminals 1 and 2.
• Terminals 3 and 4 are volt free
contacts. Live in goes to terminal 3
and Live out goes to Load.
There is no neutral switching with the
T80, ensure that maximum loading is
complied with.
Flashing colon
indicates 24hr
clock is running.
Present time and day
1) Keep button depressed during the
entire “present time and day” setting
procedure.
2) Set the present time using buttons
“h+” and “m+”.
If you keep buttons “h+” and “m+”
depressed for longer than a second the
figures in the display will scroll
continuously. Set the present day of the
week using button “Day”.
3) Release button . The clock is now
running. The flashing colon indicates
this. Use a reliable time signal
(e.g. telephone or radio) to set the
clock accurately to the minute.
When the timer is new or when it has not
been used for some time it may need to
be “charged”.
To do this, connect to power.
The built-in rechargeable battery will
begin to charge.When symbols appear in
the display (after approx. 2 minutes),
press the “Reset” button (use a pencil or
pen).
C
aution: this will cancel all memory
including timer settings. The timer will be
‘clean’ for new commands. If a power
failure should occur (or should the timer
be disconnected from the power supply
for a short time), the built-in rechargeable
battery will then provide power to the
clock and guarantee that the time and
switching programmes are retained and
not disturbed or lost.
