6440330 Digital 4-channel timer clock, TR 644, year program, app

Thanks to the integrated astro program, the Theben TR 644 top3 BLE RC digital year timer clock can automatically determine the exact times for sunrise and sunset throughout the year in addition to classic time functions. The timer clock can be synchronised via external DCF or GNSS antennae. If a GNSS antenna is used, the exact position is also determined automatically. With four independent switching channels and two external inputs, this timer clock offers comprehensive and flexible control options. External buttons or switches can be used to conveniently activate sequence timers or implement continuous switching. In addition to direct programming on the device via an integrated Bluetooth BLE module (can be deactivated), app control via smartphone or tablet is also possible. Optional PIN coding protects against unauthorised access.
