INSTALLATION
• The instrument is supplied with the battery not inserted to avoid
wasted consumption. Extract the battery from its packing and insert
it into the housing located behind the instrument so that pole (+)
is visible as shown in the figure. Then secure the closure cover,
turning it clockwise.
• Using a pointed object press key “R”
to perform a reset. All the segments
of the display will light for a few
seconds and then the instrument shows
the version of the firmware and the type of instrument.
• At this point it is possible to insert the parameters necessary for the
instrument to work correctly:
− language
− date format
− date
− time
Setting language
It is possible to choose from 5 languages:
Italian ´English ´Spanish ´
French ´German
Use keys “C1” and “C2” to choose
the desired language.
Press “Ok” to confirm and go on to the
“data format” menu.
• Connect the load and the power supply as illustrated in section
“Connection diagrams”

The instrument then goes into normal
operational status and is ready to work.
The display shows the values for the date,
time, status relay, day of the week (on
the first line in letters and lower down in
numbers) and the DST/CET symbol.
Note: if the instrument is not fed by
the mains, on the first line of the

ON/OFF Events
ON and OFF events consist of switching the relay to the on or off
position.
They may be daily (every day at the same time) or weekly (one or more
days during the week, each week).
IMPULSE events
An impulse event can be an on or off type and may last for a maximum
of 59 second:
ON OFF
At the end of the on impulse the relay will always be in the off status; at
the end of an off impulse the relay will always be in the on status.
An impulsive event can be interrupted following a manual operation.
CYCLE events
A cycle event is a programme which repeats itself over a preset period
of time (maximum duration 1 week) during which there is a succession
of on and off switching.
The cycle programme always starts from the on status and always ends
in the off status. The duration of the on and off status cannot be less
PROGRAMMINGS

User manual memo DW E
ON OFF
than one minute.
The cycle event may be interrupted following a holiday event (relay
status:off), a manual operation, a date/rime change, automatic updating
of CET/DST time (we recommend disabling the automatic time change
when using the cycle programme).
HOLIDAY events
A holiday event allows you to enter individual days or holiday periods
during which all the set programmes shall not be carried out and the
relay shall be in the off position.
Holiday events always start at 00:00 on the starting day and end at
23:59 on the last day of the holiday.
Holiday events are interrupted in the case of manual operations on
output.
Programming priority
In automatic function mode the instrument behaves as foreseen by the
entered programmes. Should there be conflict between programmes
(different events starting at the same moment) the instrument will only
run the one with the highest priority, according to the following table
(1 maximum priority):
Event Weekly Daily
Cycle 1 -
Impulse 2 3
ON or OFF 4 5
Programmed events which starting during an event already in progress
(holiday, cycle) are ignored.
In the case of non-instantaneous (holiday, cycle, impulse) the device
always completed the started programme before managing the next.
Exceptions to this are cases in which:
- a holiday event occurs while executing a non-instantaneous
programme
- there is a change to manual operation while executing a non-
instantaneous programme. In this case all the programmes running are
interrupted and if there is a lock or random on the channel, execution
of all programmes is disabled until manual procedure is deactivated
Programmes that are active when one of these exceptions occurs are
interrupted and will not be restored. When execution is interrupted, the
relays still maintain status unless entering a holiday day (or period).

MANUAL OPERATION
Manual operations are reachable from the
normal operational status in which the
display assumes an appearance similar to
the following:
Manual switching on/off
Briefly pressing keys “C1” allows
switching The achieved status is
maintained until the next programmed
event.
Casual on/off switchings
It is possible to activate casual output
switching.
Activation brings the output to the on
status and shall then be followed by on/
off switching with casual periods and
duty-cycles (the default minimum period
is 1 minute and the maximum 5 minutes:
such values can in any case be changed
in the settings menu)
Hold keys “C1” and “Ok” down
simultaneously for 3 seconds to activate
the function.
On confirmation of activation, under the
output status indication appears the
symbol .
Pressing keys “C1” and “Ok” again for 3
seconds deactivates the function.
The relay is set to off status.
Lock output switching (Lock)
It is possible to activate the function
which allows all the switchings of one
output to be locked. In this way all the
programmes are locked (including the
holiday programme and the other manual
switchings) and the output is maintained
in its current status until manual
unlocking.

Battery Test
The battery is read automatically once a week (Monday at 00:00). It is
in any case possible to read battery status by holding down key “ ”
for 3 seconds. On the display appear the words if the
battery charge level is sufficient for correct operation; otherwise the
words appear to indicate that replacement is required as
soon as possible.
The manual functions which work on the output relays have
priority over any set programming.
The highest priority function is the lock switchings function
(LOCK).

Press “Ok” to confirm.
Confirmation of programming is shown by
the words on the display.
Note: recursive function
t this point the instrument activates the
recursive function which allows several
on-off events to be programmed in
succession on the same day.
Thereby once an activation (deactivation)
event has been programmed, it is possible
to enter the time of a deactivation
(activation) event for the same day.
If you do not wish to enter an off (on) time, press key “ ” to terminate
programming.
There is no control of the correlation between on/off events
programmed using the recursive function: such function is therefore to
be intended as facilitated programming.

programme in the memory in order to enter a new one.
The message is shown on the display whenever there
is an attempt to save a programme overwriting a pre-existent
programme of the same type (for example trying to enter a daily
off event at 08:00 if there is already a daily on event at the same
time).
