USER MANUAL
The digital time switches of memo BT GPS series are electronic devices for the management of the electrical utilities with a programming of
time or astronomical type.
They have one (memo BT1 GPS and memo BT Y1 GPS) or two (memo BT2 GPS and memo BT Y2 GPS) independent relays (channels).
In the 2-channel models, the relays can also be configured independently with an hourly (one) and star (the other) programming.
The bluetooth interface allows it to be coupled with mobile devices (smartphone or tablet). Thanks to the free app that can be downloaded
from the AppStore and Google Play stores, it is possible to program and make settings directly on your smartphone, and then transfer all the
data to the time switch. The reverse procedure is also possible, i.e. to copy the programming of a time switch on your mobile device.
The device is equipped with an input for synchronization from external GPS that allows the updating of data such as: date, time, latitude,
longitude.
The backup battery allows you to keep the settings even in case of black-out and can be replaced through the cover on the back of the time
switch.
The switches of memo series perform actions of 1BTU type and are intended to operate in environments with III overvoltage category and
pollution degree 2 in accordance with EN 60730-1 standard.
Code Model Description
memo BT1 GPS Daily / weekly / astronomical switch with 1 relay and Bluetooth and GPS interface
memo BT2 GPS Daily / weekly / astronomical switch with 2 relays and Bluetooth and GPS interface
memo BT Y1 GPS Daily / weekly / yearly / astronomical switch with 2 relays and Bluetooth and GPS interface

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, memo BT GPS:
- 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 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 the hour and the minutes
In Italy,for example, daylight saving time (DST) begins the last ( ) Sunday ( ) of March ( ) at o’clock and ends the last
( ) Sunday ( ) of October ( ) at o’clock.

User manual memo BT GPS
Astronomical coordinates setting menu
The setting of the geographical coordinates of the installation place allows memo BT GPS to calculate, for each day of the year, sunrise and
sunset times. To simplify the procedure, in the memo BT GPS 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 (menu ).
Note: if the display at point shows “---------” it means that the latitude and longitude 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. Finlandia: Helsinki, Hämeenlinna,
Hyvinkää, Iisalmi, Joensuu, Jyväskylä, Kajaani, Kemi, Kokkola, Kotka, Kouvola, Kuopio, Kuusamo, Lahti, Lohja, Lappeenranta,
Mikkeli, Oulu, Pori, Porvoo, Raahe, Rauma, Rovaniemi, Saariselkä, Salo, Savonlinna, Seinäjoki, Tampere,Tornio, Turku, Vaasa,
Varkaus.
The correction of sunrise and sunset times is usefull when the presence of disturbing elements, such as the mountains, influences 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. With memo BT GPS 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.
