IMPORTANT
This unit should be installed by a
competent person in accordance with
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.
INSTALLATION
• 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.
HOW TO OPERATE
When the timer is new or when it has not
been used for some time it may need to
be “charged”.

begin to charge.When symbols appear in
the display (after approx. 2 minutes),
press the “Reset” button (use a pencil or

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.
HOW TO SET

EXAMPLE
NOTE: Be sure that the desired day or
days are chosen on both the ‘on’ and the
‘off’ displays.
EXAMPLE
“DAY” BUTTON SELECTIONS
Every day of the week
If you do not enter the day when setting a
switching command, the switching will
be carried out at the set time on every
day of the week.
Only one day of the week
If you enter a particular day while setting
a switching command (using button
“Day”), the command will be carried out
at the set time only on that specific day of
the week.
Abbreviations
MO = Monday, TU = Tuesday,
WE = Wednesday, TH = Thursday,
FR = Friday, SA = Saturday,
SU = Sunday.
On a weekly combination (or ‘block’
programming) of days
When pressing button “Day” several
times, you will find by means of the
display that three combinations of days
are also possible:
MO TU WE TH FR = Monday to Friday
SA SU = Saturday and Sunday
MO TU WE TH FR SA = Monday to
Saturday
If you enter these combinations of days
instead of one individual day, the on/off
command will be carried out at the set
time on each of the corresponding days
of the week.
This programme will repeat itself week
after week until the programme is
changed or the timer is disconnected.
HOW TO CHECK, CHANGE
OR DELETE SWITCHING
COMMANDS
Checking
By pressing button “Timer” a number of
times you can make the switching-on and
switching-off commands visible in the
isplay: first the set commands are
d
presented and then the free spaces.
Changing
You can change a switching command by
aking it appear on the display and
m
pressing “day”, “hour” and “minute”
buttons accordingly.
Deleting
elete a timer command period (an ‘on’
D
and ‘off’ time) by pressing the “timer”
button until the required program
number on time is displayed in the
window and pressing h+ until -- is
displayed immediately after 23. Do the
same with m+ until -- appears after 59.
Repeat this sequence for the ‘off’ mode.
The deleted command then becomes
available for reprogramming. Press
button “Timer” after changing or deleting
a command to save the new command.
Switching back to present time
After setting the switching commands
you return to normal time reading by
pressing button.
Is power being supplied to connecting
load?
The word “ON” or “OFF” in the display,
above the time reading, informs you
about the actual switching condition.
OVERRIDE SWITCH
When in the “off” mode pressing the
button marked will switch “on” the
power to the load connected to the timer.
If the button is pressed again the power
will switch off. If the button is not
pressed again, power will remain on until
the completion of the next on/off
command when power will switch off.
If not pressed again the power will
remain off until the following ‘on’
command has been reached.
