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).
