The Finder 12.A1/A2 is a digital astro time switch programmable via NFC using the Finder Toolbox app. It supports Astro ON/OFF, standard ON/OFF, and Pulse functions. The device features a backlit display (when powered) and is powered by a CR 2032 battery for memory backup.
Device Overview
The display indicates the current time, day of the week, active channel functions (ON, OFF, Astro, Pulse), and program status. The 12.A1 model features one channel (SPDT), while the 12.A2 model features two channels (DPDT).
Settings
To enter settings, hold the button for over 3 seconds. You can configure the country, postal code (CP), year, date, time, and daylight saving settings. Geographic coordinates (Latitude/Longitude) and time zone can also be set manually if required.
Programming
