The Schneider Electric Twilight Switch IC Astro (CCT15225) is an advanced, programmable twilight switch that allows for the automatic switching on and off of electrical consumers such as lighting systems. Instead of relying on a light sensor, the device calculates sunrise and sunset times based on geographical data. Programming can be done directly on the device or via the Acti 9 Light and Time Switch smartphone app, which utilizes a Bluetooth connection. Alternatively, programming via PC with a special programming kit is also possible. The twilight switch offers a variety of features, including the ability to set thresholds for light sensitivity and choose different astronomical modes. With a user-friendly interface and an LCD display that shows the current time and day of the week, the IC Astro is a practical solution for automating lighting systems.
