■ Operates as a normal light switch - or can be quickly switched
to ‘automatic’ for timer control.
■ If required, several may be used in key rooms of the house to
simulate a ‘lived in’ appearence.
■ Has ‘random’ setting to simulate ‘lived in’ situations when the
home is vacant.
■ Accurate 24 hour digital clock.
■ Backlight turns on with first button press.

* GU10 240V Halogen Downlights can damage the XL770T when
they fail, and are therefore not recommended for use with this product.
** A minimum load of 10W can be achieved if a resistive load is
connected in parellel with the fluorescent load. This can be, for
example a resistor or incandescent lamp rated at least 10W.
*** Power factor correction capacitors must be placed on the
line side of the XL770T. If this is not possible then they should
either be removed, or a 36W magnetic ballast should be
connected in parallel with the fluorescent load, to prevent
damage to the XL770T.
**** Refer to the following table for VA ratings when power factor
correction is not used:

N.B. If connected incorrectly or if load exceeds the above values,
an internal fuse will rupture, rendering the unit inoperable.
WHAT TO DO IF THE DISPLAY IS BLANK
When this unit is not connected to power for a long period
of time, the back-up battery will run down and the display
will go blank. When power is re-connected, wait for about 20
minutes for the internal battery to charge up before attempting
to program the unit. After this time, the display may still not
return to normal. If this should happen, press the reset button,
see Fig 1, using a small insulated object.
This procedure will erase the memory contents of the unit.

Setting the ‘switching off’ days and times
Having set the day/s of operation and the ‘on’ time, the ‘off’ time
must be chosen, otherwise the light/s will stay on permanently
from the ‘switching on’ time setting. After setting the ‘on’ time,
press set again to enter the setting for program 1 ‘off’ time.
Please note that the program 1 ‘on’ time will automatically be
copied to the ‘off’ time to make setting easier.
Press the ‘Hrs’ and ‘Min’ keys as before to set the ‘off’ time.
If, for instance, you wish the lights to turn off on Sunday (as in
‘on’ program) at, say, 23:15 hours (11.15pm), you must set the
‘off’ time as:
Press the ‘Day’ key to change the day you wish the lights to turn
off. However, this cannot be done if you have selected a group
of days, such as Monday to Friday.
When the program on/off time has been set properly, press
the ‘Set’ key once. This will allow you to set the ‘on’ time for
the next program.
Setting present day and time
In ‘clock’ mode, press the ‘Set’ key. A clock icon will appear at
the top right. The timer is now in ‘clock setting’ mode. (If no key
is pressed for 60 seconds, the timer will automatically revert to
‘clock’ mode.)
Clock setting mode
While the clock icon is flashing, press ‘Day’ until the present day
is illuminated at the bottom of the display, ‘Hrs’ until the present
hour appears (this is a 24 hour clock), then press ‘Min’ until the
current time is reached. By pressing and holding either the ‘Hrs’
or ‘Min’ key, the digits will increment automatically, and similarly
for the ‘Day’ key. The setting below represents 5.35pm
on a Monday.
‘Day’ and ‘time of day’ display
Setting the ‘switching on’ days
While in ‘clock setting’ mode, press ‘set’ once. The timer is now
in ‘program setting’ mode. (If no key is pressed for 60 seconds,
the timer will automatically revert to ‘clock’ mode.)
The display will show a flashing 1. This signifies that this is the
first of 8 programs.
By continually pressing ‘Day’, different days will be illuminated
at the bottom of the display. These indicate the days that the
timer will operate. For instance the above display signifies the
timer will come on during weekdays only (not weekends).
Pressing ‘Day’ once gives the following display:
This means that the timer is to operate during weekends only.
If ‘Day’ is pressed again all the days of the week will be
displayed, meaning the timer is to operate everyday. The next
press will highlight Su, then Mo, then Tu etc. Each progressive
press will highlight another single day, the timer to operate on
that day only.
Setting the ‘switching on’ time
With the 1 flashing, set the ‘switching on’ time for the first
program by pressing the ‘Hrs’ and ‘Min’ keys.
This display shows that the timer will operate on Sunday only
and the light/s will come on at 6.30pm.

Note 1: The same on/off times can be set every day or on selected days. These
settings will occupy one program only.
If different on/off times are required on one night (say 3 different settings) then
3 programs would need to be utilised.
There are 8 programs in this timer which provide a maximum of 56 on/off
settings per week.
Note 2: Say for example that you are installing the timer at 11.00am. You set
the timer to turn on at 9.00am and off at 5.00pm. You will have to wait until
9.00am the next morning for the timer to turn on.
Press ‘Set’ after program 8 off time setting and the timer will
go back to ‘clock’ mode and show the current time.
Disabling program(s)
If you wish to cancel a particular program you may press
‘Man’ when that ‘on’ or ‘off’ time is displayed in ‘program
setting’ mode.
By doing this the black ‘ ’ icon appears on the top right of
the screen, which disables that time command.
If, for instance, the timer was programmed to switch on at 19:30
on Wednesday and turn off at 23:15, then by displaying the ‘on’
time (19:30) and pressing ‘Man’, the ‘ ’ icon would appear
and the lights would not switch on. Alternatively, if the turn-off
time of 23:15 was displayed and the ‘Man’ key pressed, the
result would be that the light would not switch off at 23:15 and
would remain on until the next switch-off time occurred.
To resume normal operation, view the time which had previously
been cancelled and press the ‘Man’ key again. The ‘ ’ icon
should disappear, and the program will be reinstated.

Using manual override
There are two ways to override the timer:
1. Turn the MAN/AUTO switch to the MAN position.This allows
the adjacent switch to operate as a normal light switch. In this
mode, the words ON and OFF on the LCD display will not
necessarily reflect the state of the light.
2. Press the ‘Man’ key (under the Excel cover). This will toggle the
light on and off. The words ON and OFF on the LCD display will
show the state of the light. If the word is flashing, this means that
normal programs have been overridden until such time as the
‘Man’ key is pressed again.
Placing in ‘Random mode’
Random mode switches the light/s on and off in a random
fashion, giving an appearance of the house being lived in.
Random switching is unpredictable, but the time the lights are
on will be between 10 minutes and 30 minutes.
Random mode is set by pressing the ‘Hrs’ button for 3 sec. It is
denoted by the following icon on the display:
When random mode is set, random ON/OFF switching will only
occur between the ON/OFF times in the 8 programs. If no
programs are set, no random switching will occur.
To exit random mode, press and hold the ‘Hrs’ button
for 3 sec.
Reading the program
In ‘clock’ mode, press the ‘Set’ key until the clock face icon
appears as a flashing sign at the top right of the display.
Continue to press ‘Set’ and the display will show ON/OFF times
and step from program 1 to 8.
Pressing ‘Set’ further, the timer will then revert to ‘clock’ mode.
Daylight saving time adjustment
In ‘clock’ mode, press and hold the ‘Min’ key for 3 seconds.
‘ST’ will appear on the display.
Press ‘Hrs’ key once to decrement the hour by 1 (-1).
Press ‘Hrs’ key again to increment the hour by 2 (+2).
Press ‘Hrs’ key again to decrement the hour by 1 (-1).
Press ‘Hrs’ key again to decrement the hour by 1 (-1).
Press ‘Hrs’ key again to increment the hour by 2 (+2).
ie. the adjustment pattern is: -1, +2, -1, -1, +2, -1,...
When the adjustment has been made press ‘Min’ key to confirm
the setting and return to run mode. This will advance or retreat
all the time settings.
One Touch countdown timer
This feature can be used to switch the lights on for 10, 20, 30,
40 or 50 minutes.
To activate the countdown timer hold down ‘Day’ key for
2 seconds. The display will show 10:00 with ON symbol
showing. Repeatedly pressing the ‘Day’ key will increment the
timer value in steps of 10 minutes, until the maximum of 50:00 is
reached. The countdown will begin immediately.
When countdown is operating all preset programs or the
random function will be temporarily suspended.
The countdown feature can be cancelled at any time
by pressing the ‘Man’ key.
