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

Thanks to its built-in astro program-in addition to standard timing functions-the Theben TR 644 top3 BLE RC digital annual timer can automatically determine the exact times of sunrise and sunset throughout the entire year. This enables precise control of lighting systems and other electrical loads based on these parameters. Of particular note is the choice between the preconfigured astro modes: sunset, twilight, or complete darkness, with sunrise and sunset times further adjustable via an offset. The TR 644 top3 BLE RC can also be synchronized via external DCF or GNSS antennas. When a GNSS antenna is used, precise position determination occurs automatically, making the Astro function even more accurate.

With a total of four independent switching channels and two additional external inputs, this timer offers particularly comprehensive and flexible control options. Countdown timers can be conveniently activated or continuous switching operations implemented using external pushbuttons or switches.

Various switching modes-such as ON/OFF switching, nighttime interruption, pulse switching (e.g., astro-pulse for controlling shading), and cycle programs for recurring tasks-allow for customization to meet specific needs. A well-designed vacation program ensures efficient control during extended periods of absence. Two programmable random modes simulate occupancy to effectively provide additional security.

The wide range of functions offers virtually limitless applications: whether for demand-based storefront and advertising lighting outside of business hours, for controlling blinds and ventilation systems, or for automatically lighting schools, daycare centers, parking lots, or public spaces-with an impressive 800 memory slots, even complex time schedules can be managed easily and clearly. Even the WWF’s Earth Hour is already pre-programmed into the TR 644 top3 BLE RC through the year 2044.

Operation is particularly convenient: In addition to direct programming on the device, the integrated Bluetooth BLE module (which can be deactivated) also enables straightforward app control via smartphone or tablet. The proven DuoFix spring-loaded connection technology guarantees secure, fast, and convenient wiring of two conductors (0.5-2.5 mm²) at a time. The practical release button makes wiring and subsequent adjustments particularly easy.

The TR 644 top3 BLE RC features a built-in lithium battery that ensures an impressive operating life of up to ten years (“Install and forget"). Reliability is ensured by an integrated zero-crossing circuit, which protects the relay contacts even under high LED loads of up to 600 W. Despite 5 times the LED power compared to the top2 devices (now up to 600 W), standby power consumption has been reduced by 60% to just 0.5 W.

A clearly structured, backlit display with user-friendly menu navigation makes operation a breeze. Preset date and time values allow for quick and easy setup. Even without mains power, the timer remains fully programmable. Optional PIN coding provides reliable protection against unauthorized access.

The TR 644 top3 BLE RC is rounded out by practical additional features such as an operating hours counter, a reset function, and a service function for monitoring upcoming maintenance. Whether for commercial use, demanding industrial applications, or private households: With the Theben TR 644 top3 BLE RC, you’re choosing high-performance technology, outstanding quality, and intuitive operation. The annual timer is “Made in Germany," with development, production, and 100% final inspection taking place at the Haigerloch manufacturing site.

Theben annual timers are also available with 1 channel (TR 641 top3 BLE RC, part number 6410330) or 2 channels (TR 642 top3 BLE RC, item number 6420330), as well as a 2-channel version with a special voltage range of 12-24 V (TR 642 top3 BLE RC 12-24 V, item number 6424330).
