Daylight saving time (DST)/winter time (CET) change setting menu
Daylight saving time (DST)/winter time(CET) change and vice versa can occur in an automatic way. In this case, the device:
- increases by an hour in the passage from winter time (CET) to daylight saving time (DST) ( )
- decreases by an hour in the passage from daylight saving time (DST) to winter time (CET) ( )
For every time change it’s necessary to specify:
the week of the month during
which the time change occurs
(first, second, third, fourth, last)
the day of the week
(Monday: 1, Tuesday: 2, ...)
the month hour and minutes
In Italy, for example, daylight saving time (DST) begins the last ( LAST ) Sunday ( ) of March ( 03 )at 02:00 o’clock,
and ends the last ( LAST ) Sunday ( ) of October (10) at 03:00 o’clock.

Astronomical coordinates setting menu
The setting of the geographical coordinates of the installation place allows the device to calculate, for each day of the year, sunrise and
sunset times. To simplify the procedure, in the device are stored the coordinates of the locations listed below; if your location is among them
you can select it from the menu , otherwise it’s necessary to enter the coordinates of latitude and longitude (menù ).
Note: the display on point shows “---------” if the coordinates have been entered.
Stored location: Italy: all provinces. United Kingdom: Cardiff, Belfast, Edinburgh, London. Spain: Barcelona, Madrid, Seville, Valencia
France: Lyon, Marseille, Paris, Toulouse. Germany: Berlin, Hamburg, Cologne, Monaco
The correction of sunrise and sunset times is useful for applications that require the turning on of lights in particular localities. It’s possible, in
fact, that the presence of disturbing elements, such as the mountains, can influence actual times of sunrise and sunset, making it necessary
to advance or delay of a few minutes the calculated times.
The twilight is the time interval before sunrise, or after sunset, characterized by the permanence of the light due to the spread by the
atmosphere of the Sun light. During these time intervals it’s possible to distinguish clearly objects and conduct outdoor activities without
using additional lighting. Therefore, in some applications it is more interesting to take as times of switching on and off the twilight (civil)in
place of sunrise and sunset. With the switch Tempo it’s possible to choose to turn on/off the loads depending on the times of sunrise
and sunset or the civil twilight. The calculated time correction also applies to the times of twilight.
To view the calculated switching on time (sunset) and switching off time (sunrise), from the main screen press the key .
The times displayed take into account any corrections entered.
If the display shows it means that the calculated sunrise time is after the sunset time. If the display shows it means that
the calculated sunrise time is before 00:00 or that the calculated sunset time is after 23:59.

Random switchings setting menu
The “random switching ” function (which can be activated by pressing the keys and simultaneously for more than 3 seconds)
allows the relay to switch automatically and at random time intervals.
In this menu it’s possible to define the minimum and maximum duration of the time interval between two random switchings. Default mini-
mum duration is 1 minute, maximum duration is 5 minutes.
Parameters modification
1Set the minimum duration. It’s possible to set values between 1 minute and the maximum duration.
2Set the maximum duration. It’s possible to set values between the minimum duration and 23:59 hours.
Note: setting the minimum duration equal to the maximum, the switchings will occur at fixed time intervals.
