USER MANUAL

The digital time switches of memo AST are electronic devices for the management of electrical loads between sunset and sunrise times (astronomical program). It has a NFC interface that allows it to be coupled with mobile devices (smartphone or tablet and, thanks to the free app that can be downloaded from Google Play store, 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 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 time switches of Memo series are devices that perform actions of 1B type, intended to operate in environments with III overvoltage category and pollution degree 2 in accordance with EN 60730-1 standard.

Astronomical coordinates setting menu

The setting of the geographical coordinates of the installation place allows memo to calculate, for each day of the year, sunrise and sunset times. To simplify the procedure, in the memo 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.

Location stored in memo: - 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 memo 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).

Random switchings setting menu

The “random switching ” function (activated with the combination described on page 6) allows the channel on which it’s active to automatically switch 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 minimum duration is 1 minute, maximum duration is 5 minutes.

Parameters modification

Set the minimum duration. It’s possible to set values between 1 minute and the maximum duration.

Set 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.

To activate PIN protection:

- set a value between 000 and 999

To disable PIN protection:

User manual memo AST NFC

Memo AST carries out programs of astronomical type, i.e. in the interval delimited by sunrise and sunset*: ON/OFF, ON pulse, OFF pulse, holiday, night programs (see pages 30-31). ON switchings set before sunset are carried out at sunset, OFF switchings set after sunrise are carried out at sunrise (except for some night programs that can have switching on or switching off during the day. See on page 30).

* times of sunrise and sunset are automatically calculated by memo according to geographic coordinates set during installation. In place of

sunrise and sunset times it’s possible to use the times of civil twilight (see page 18).

Programs types

• ON/OFF program : is composed of a switching of the ON relay and of a subsequent switching of the OFF relay. It can have a daily period (everyday with the same modes), weekly (every week with the same modes)*.

• PULSE ON program: is an ON relay switching for a maximum duration of 59 seconds. It can have a daily period (everyday with the same modes), weekly (every week with the same modes)*.

• PULSE OFF program: is a relay switching OFF for a maximum duration of 59 seconds. It can have daily period (everyday with the same modes), weekly (every week with the same modes)*.

• HOLIDAY program: is a period of time defined by a start time and an end time within which all programmed switchings (of that channel) are disabled. The relay is in OFF position (OFF holiday) or in ON position (ON holiday).

English

User manual memo AST NFC

 Important: on the same channel can’t coexist ON pulses and OFF pulses (if an ON pulse is already present, it’s not possible to save a

holiday OFF program and vice versa).

 Important:

on the same channel can’t coexist holiday ON programs and holiday OFF programs (if a holiday ON program is already

present, it’s not possible to save a holiday OFF program and vice versa).

Programs priority

The priority programs defines how memo manages the case in which programs with different period are running at the same time (1 indicates higher priority).

Program

Date* Annual Monthly Weekly Daily Holiday 1 Night

2 Pulse 3 On/Off 4 5

* Date: select day, month, year (program carried “only once in the life of the product”). If the month is not specified, the program is carried

out all days xx of all months of the specified year.

User manual memo AST NFC

Priority on/off programs

In case in which, on the same channel, on/off programs are provided with different period (daily or weekly) to carry out in the same day, only the program with the highest priority is executed.

Holiday program

The holiday program just begins and ends exactly at the specified times.

From this example it’s possible to see that the daily event on Monday is not carried out because in the same day it is provided the beginning of the week program (even if the daily program

of Monday begins and ends before the beginning of the weekly program). Instead, the daily program of Sunday is carried out because it’s the only one running for that day.

• EN 60730-2-7

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

- replace the battery and 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 replacement doesn’t exceed 60 seconds (in absence of power by means).

Dispose of the used batteries observing the laws in force

in relation to the disposal of hazardous waste.
