Theben

More Theben Products

Theben produce a wide range of actuators and motion sensors with up-to-date features and functions that make life easier for the installer, and the control better for the building. With their own VDE test laboratory, all their products are tested to the highest global standards.

Actuators

Theben produce stand-out KNX actuators for high-density switching, dimming, and shading control. Their actuators are highly reliable and enable manual control for pre-commissioning testing and screen terminals for easy connection.  Theben's zero-crossing and inrush management make their LED lighting relays long-lasting. Their heating actuators for underfloor and fancoil applications are packed with intelligent functions that make installation and integration a breeze.

Weather Stations

The Theben Meteodata weather stations are made with clear plastic, helping them blend into the built environment.  With measurement for wind speed, temperature, 3 x brightness, and rain, the sensors know with GPS the time of day and location, so can accurately control multi-facade shading.

Sensors

The wide range of Theben's motion and presence sensors means there is the right sensor for every application, from wide-open spaces like classrooms, to corridors where long thin beams of detection are necessary, to presence detection in rooms to keep lights on whilst people are working.

The company acquired the swiss sensor company HTS who pioneered the PIR motion sensor and has remained at the forefront of the technology introducing new products that push forward the use of sensors into a wide range of applications.

Theben presence detectors provide every option for energy-efficient and intelligent lighting control. In addition to lighting control in offices and public buildings, you can also control heating and air-conditioning based on presence. This lets you save energy costs and reduce CO2 emissions. Presence detectors react to the slightest of movements and measure room brightness at the same time. If no movement is detected, or a defined brightness value is exceeded, the presence detector automatically switches off or dims the light.

Presence detectors work with the same principle as motion detectors: They detect thermal radiation in their surroundings. If thermal radiation is detected in the detection area, the detector converts the radiation into a measurable electric signal, and the light is switched on. The difference between motion and presence detectors lies in the sensitivity of the sensors. Presence detectors have more sensitivity than motion detectors and detect the smallest movements with the detection area divided evenly into 1000 zones. Like a chessboard, the zones run through the entire detection area. Even slight changes in the thermal image, such as typing on the keyboard in an open-plan office will be detected. In contrast, a motion detector only responds to greater changes in the thermal image and is suited for applications with larger, walking movements or outdoor use.

A further difference between motion and presence detectors: light measurement. A motion detector measures brightness once when the light is switched on because of movement. If it continues to detect movements, even though daylight would be sufficient, the light remains switched on unnecessarily. In contrast, presence detectors constantly measure brightness: if a defined value is exceeded, the presence detector switches the light off, even if it detects movement. This further reduces energy costs and CO2 emissions.

Due to very fine sensor technology, Theben presence detectors react to the smallest movements and temperature differences. This allows you to adjust lighting and air conditioning to the exact needs of occupants. Depending on the model, Theben presence detectors are available in black, white, grey, silver or special colours on request.

Unique Features of Theben Detectors:

Square Detection Areas

As most rooms are square or rectangular, Theben sensors use a square detection area to simplify planning. The detection areas can be lined next to each other with no gaps. Another practical benefit is no "blind spots" or overlaps in the room. Movements are guaranteed to be detected everywhere.

Self-Learning Time Delay

The time delay changes automatically depending on people's habits in the room. If the presence detector detects more movement, the time delay is shortened to as little as two minutes. If people hardly move or only rarely, the time delay is increased to up to 20 minutes. This saves energy, boosts comfort, and allows people to work the way that suits them.

Sensitive Room Monitoring

A presence detector misses nothing. This is an advantage when the presence detector is integrated in the building system technology of large office or administration buildings. Building management know if rooms are still occupied.

Safe Staircase Light Function

In the event of a short stay, the light is only on for two minutes. But because presence detectors can detect how long someone is a space, it does not automatically trigger a time delay. This is critical for applications where sensors are used in stairways.

Custom Lighting Scenarios

Bright daylight or softly dimmed light – choose between two lighting scenarios, which can easily be defined. For example, in conference rooms when the light has to be dimmed for presentations. Settings can be made, saved, and changed easily using remote control.

Practical Pulse Function

The pulse function allows Theben presence detectors to be built into existing automation installations with timer switches or KNX binary inputs without expensive adjustments.

Intelligent Parallel Switching

Via master/master/parallel switching operations, the lighting conditions can be set for the detection area of devices individually. This is an advantage in open-plan offices when different lighting conditions are balanced between areas close to windows and the room's interior.

IP Rated for wet protection

Presence and motion detectors with protection class IP 54 can be used in wet rooms such as showers, changing rooms or toilets.

High-Capacity Switching

Presence and motion detectors from Theben have a high-performance relay with tungsten pre-contact or a zero-cross switching and can handle switch loads of up to 10 amperes. This allows several lights to be connected and larger areas to be lit. This provides peace of mind during planning, lowers costs and reduces installation time.

DALI Intelligent Lighting Control

Thanks to outstanding detection quality, sophisticated functions and exceptionally easy commissioning and programming, presence detectors and sensors from Theben are the discerning customer’s devices of choice. When combined with intelligent lighting management via the DALI bus system, they really come into their own. 

One Line for Three Groups

Control two to three lighting groups with a single DALI line. This means fewer lines and reduces the amount of time and money spent on installation. No rewiring is required if any changes are made later on.

Safety from Orientation Light

In buildings such as hotels or hospitals, an orientation light enhances the feeling of safety. If movement occurs, the lighting is dimmed up to the setpoint value and then back down to the level of the orientation light after a defined time delay

DALI 2 presence sensors

Perfect light management can be achieved with a master controller and presence sensors. The DALI-2 standard ensures compatibility across manufacturers. This allows the DALI-2 presence sensors to be operated with any Multimaster-Application-Controller that complies with IEC 62386 Parts 101/104. As an input device, the presence sensor provides information regarding presence detection and light measurements in accordance with IEC 62386 Part 303 or Part 304 via the DALI bus. The master controller oversees full functionality such as switching, constant lighting control, fully/semi-automatic, manual override, scenes, etc. The DALI-2 presence sensors also support remote control commands for dimming or switching lamps, controlling blinds or other functions. 

Planning Security

As a member of the European association and quality label sensNORM, Theben is committed to greater transparency, quality and planning certainty for motion and presence detectors in building automation. Products carrying the sensNORM quality label have been tested in line with standardised test specifications, allowing consumers to make a genuine cross-brand comparison. The measuring method ‘sensNORM’ has established itself as an industrial standard and was included in the European standard IEC 63180. The measured detection areas according to sensNORM can be found in the data sheets of our respective products.
