For applications where the need to
control lighting, temperature
or other functions according
to daylight hours exists,
Finder has developed an
easily programmable time
switch which uses a special
digital program to calculate
sunrise and sunset times by
simply entering a location’s
postcode with a single joystick.

The Astro 12.81 time switch will
control lighting, heating/cooling
and humidity equipment in
industrial, commercial and
residential applications wherever
sunrise and sunset times are
critical.

The Astro’s micro-controller
stores postcode data from 16
European countries, including
the UK, allowing for a precise
calculation of seasonal sunrise
and sunset times through date
and location coordinates.
