The
memo AST1
is a digital programmable switch used to manage electric utilities between
the hours of sunset and sunrise, which are automatically calculated by the instrument based on
the geographical coordinates inserted.
The cover on the back of the instrument makes it possible to replace the battery when it is run
down, whereas the integrated IR receiver makes it possible to exchange programs between the
instrument and the remote control.
