Set consisting of a digital multifunction timer switch 1-channel and brightness built-in sensor. The digital multifunction timer switch 1-channel features an integrated Bluetooth function and app programming. It allows for time, brightness, and location-dependent control with a changeover contact for load on/off or twilight switch function, as well as buttons/switches for exceptions. Usable as a daily, weekly, yearly, and astro clock, additionally with an integrated twilight switch function.

Exception control is carried out via a wired external switch/button or KNX radio switch/button quicklink. Programming is done through the app by activating, deactivating, and resetting Bluetooth on the device: time and date are factory set, automatic summer/winter time changeover, holiday and school vacation times can be selected based on location, access can be restricted via app or key combination, as well as temporary and permanent exception control on/off/pulse.

Programs can be created in the app, can be taken from already used templates, or exceptions can be activated. An optional portal can be used for sharing and external storage of the program. The contact load is reduced by zero-crossing switching. Programming without mains voltage is possible via the integrated power reserve (approximately 10 years).

The built-in sensor has a measuring range of 5 to 2000 lx, a cable length of 1 m, and an operating temperature of -30° to 60°C. The maximum cable length between connectable devices and brightness sensor is 100 m. Note: Communication protocol from version Bluetooth 4.2 and KNX radio RF quicklink.
