User manual memo RF
USER MANUAL
memo RF is a digital electronic clock for managing electrical users over time. Allows hourly programming (periodicity: daily or weekly) or
astronomical. memo RF does not have on-board relays but is able to drive up to 8 different channels (relays) made by radio frequency remote
actuators (available as accessories), connected through the RF BUS. Each channel can be associated with a different programming (hourly or
astronomical).
The bluetooth interface allows pairing with mobile devices (smartphone or tablet). Thanks to the free app that can be downloaded from the
App Store and Google Play stores, you can make programming and settings directly on your smartphone, and then transfer all the data to the
device. The reverse procedure is also possible, ie copying the programming of a clock on your mobile device.
The backup battery allows you to keep the settings even in the event of a black-out and can be replaced through the cover on the back of the
device.

SAFETY WARNINGS
nDuring product installation and operation it is necessary
to observe the following instructions:
1) The instrument must be installed by a qualified person,
strictly in observance of the connection diagrams shown
in this manual.
2) After installation inaccessibility to the terminals without
using dedicated tools must be guaranteed.
3) Before accessing the connection terminals, make sure
that the leads are not live.
4) Do not connect or feed the instrument if any part of it is
damaged.
5) The product must be installed and activated in com-
pliance with current electric systems standards.
6) Do not use the instrument for anything other than the
indicated purpose.
7) In the electrical system upstream of the instrument
must be installed a protection device against the
overcurrents
8) The product can be used in environments with
overvoltage category III and pollution degree 2,
according to the Standard IEC 60730-1
BATTERY MANAGEMENT
When the battery is close to empty, on the first line of the display
appears . In this case, the battery must be replaced as
soon as possible. Use only batteries of CR2032.
To replace the battery:
- disconnect the mains
- remove the battery slot cover, turning it anti-clockwise
and replace the battery
- remount the cover, turning it clockwise
- connect the power supply
Warning: do not use metal objects (such as screwdrivers) to remove
the battery because this may cause the power reserve to be canceled,
resulting in a loss of date and time.
Warning: in order not to lose the programming steps and carried out
settings, it is necessary to ensure that the time for the battery repla-
cement doesn’t exceed 60 seconds (in absence of power by means).
It is necessary to remove the batteries
before the instrument is scrapped.
In case of replacement, dispose of the batteries in the
appropriate places separate waste collection containers.

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 RF:
- 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 hour and 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 RF
Astronomical coordinates setting menu
The setting of the geographical coordinates of the installation place allows memo RF to calculate, for each day of the year, sunrise and sunset
times.
To simplify the procedure, in the memo RF 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: the display on point shows “---------” if the coordinates have been entered manually.
In the memo RF the locations of all the provinces of Italy and the main English, French, German, Spanish and Finnish cities are stored.
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 memo RF 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 page press the key (see page 8).
