With the Theben KNX presence detectors, you have every option for energy-efficient and intelligent lighting control. In addition to the classic use for lighting control in offices, corridors and public buildings, you can also control heating and air-conditioning depending on presence. This lets you save energy costs and considerably reduce CO2 emissions.
Our presence detectors work according to the same principle as motion detectors: They detect thermal radiation in their surroundings, that is in their detection area. If thermal radiation is detected in the detection area, for example caused by a person approaching the presence detector, the presence detector converts the radiation into a measureable, 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 much more sensitive sensors than motion detectors and detect the smallest of movements. The sensitive sensors divide the detection area evenly into up to 1000 zones. Like on a chessboard, the zones run through the entire detection area. Even minimum changes in the thermal image, such as typing on the keyboard in an open-plan office, will be detected.

ThePixa KNX optical presence detector detects how many people are in a room and where they are. This information is used to trigger predefined actions in KNX systems. But it is not only building automation that benefits. Building operators in particular benefit from completely new added values. For example, for the flexible organisation of desk-sharing models or for optimising room occupancy and building cleaning. thePixa is available as 24 V or 230 V operating voltage.

Due to their very fine sensor technology, Theben KNX presence detectors detect even the smallest movements and temperature differences. In this way, they allow to exactly adjust light and climate to the needs of inhabitants and users. Depending on the model, the various presence detectors are available in the colours white, grey, silver, black or in special colours upon request.
The square detection area is ideal for most rooms in which presence detectors are installed. In this way, the individual detectors can be perfectly arranged. Without any gap or unnecessary overlapping. Without blind spots. This makes planning easier, reduces the installation effort, saves energy and lowers costs – because, due to the square detection area, usually fewer detectors are needed.
Presence detectors in entrance halls or warehouses must reliably detect movements from a great height. The innovative optics ensure that the presence detector does not miss anything from an installation height of up to 15 m.
With a remote control, certain settings, including activation of the programming mode, can be made and changed conveniently from the ground. This is faster, shortens the installation time and lowers costs. And, what's more, it's safer.
"eco" stands for optimum switching behaviour. "eco plus" for maximum energy savings. By configuring, you decide what is best for you. Just as you want. Exactly how you need it. There is no easier way to save energy.
How sensitively presence detectors react to movements inside the room, is entirely up to you. The PIR sensors can be conveniently set using the remote control – according to the individual requirements of the users.
A presence detector misses nothing. This is a particular advantage when the presence detector is integrated in the building system technology of large office or administration buildings. In this way, the building management always knows in which rooms people are still working.
The KNX presence detectors feature constant lighting control, which permanently compares artificial light and daylight. They determine the desired brightness value from these two light sources. No matter how changeable the weather: The lighting conditions inside the room remain pleasantly constant.
The measured brightness value is influenced by the installation location, the incidence of light, the position of the sun, the weather conditions, as well as the reflection properties of the room and the furniture. The automatic calibration is carried out by the remote control, which has which has an integrated luxmeter. It is also possible to manually enter a lux value, or change the room correction factor. This calibration ensures that the set point value in lux will be exactly observed at each workplace.
Depending on how people behave inside the room, the time delay changes automatically. If people hardly move or only rarely, the time delay is increased to up to 20 minutes. This saves energy, increases comfort and allows people to work in their most efficient way: active and lively or still and focused.
In the event of a short stay, the light is only on for two minutes, because presence detectors "detect", whether and how long someone is in the room. This means that whoever enters the room for a short period of time does not automatically trigger the time delay that has been set but still does not have to go without light.
The integrated, calibrated light measurement provides a reliable and continual measurement of the proportion of artificial and natural light. The presence detector measures the brightness by means of up to three directed light measurements, and can thus optimally respond to the diverse conditions inside the room. This ensures optimum lighting, even under difficult lighting conditions.
Lighting conditions change quickly – it is good if you can simply save them when they are exactly how you want them to be. With the clever teach-in function, the current lux value can be permanently saved. Without specialist knowledge. By the end user. It couldn't be easier.
Bright daylight or softly dimmed light – you can choose between two lighting scenarios, which you can define whatever mood takes you. For example, in conference rooms where the light has to be dimmed for presentations. For exactly those lighting arrangements that are necessary in everyday situations. Settings can be made, saved and changed quickly and easily by using the remote control.
Presence detectors allow for more than just increasing the detection area via master/slave switchings. Via master/master/parallel switchings, the lighting conditions can be set in the detection area of individual devices independently, and thus individually. This is an advantage if, for instance, in open-plan offices, different lighting conditions are to be balanced between areas close to windows and the room's interior.
Presence and motion detectors with protection class IP 54 can also be used in damp rooms such as showers, changing rooms or toilets.
Today, room situations in offices change faster than ever. With PlanoSpot, Theben has developed the first presence detector on the market whose detection zone can be mechanically moved.
If the presence detector detects too much, its detection range can be conveniently reduced by remote control or via ETS parameters. This makes the PlanoSpot the ideal presence detector for rooms in which a flexible room layout is important. But PlanoSpot can do even more: thanks to its three directional light measurements, it ensures pleasantly constant lighting conditions. In any weather and at any time of year. And that even when no people are registered. A function that ensures comfortable lighting conditions, especially in museums, restaurants, hotels or open-plan offices.

The mirror optics of the square detection area can be mechanically tilted by up to 12° to the left and right. This allows the detection area to be shifted by up to ± 1 m to better detect changed room layouts.
The square detection area is optimal for the vast majority of rooms where presence detectors are used. This allows the individual detectors to be arranged perfectly. Without gaps and without unnecessary overlaps. Without blind spots. This simplifies planning, reduces installation effort, saves energy and lowers costs - because fewer detectors are generally required due to the square detection area.
Depending on how people behave in the room, the follow-up time changes automatically. If people hardly move or rarely move, it is extended to up to 20 minutes. This saves energy, increases comfort and allows people to work in the way that is most efficient for them: active and moving or quiet and concentrated.
PlanoSpot measures artificial light and daylight by means of three directional light measurements. The middle light measurement detects the brightness directly below the detector, while the other two light measurements detect the brightness near the window or inside the room. The result: optimal lighting conditions in the entire room.
Daylight incidence, reflective surfaces or strong colour contrasts of the interior design have an influence on the lux value. It is good to know that there is a room correction factor. This automatically adjusts the measured brightness value of the corresponding light channel to the conditions in the room.
In buildings where you don't know your way around, such as hotel or hospital corridors, a dimmed orientation light provides safety. If movement is detected, the lighting is dimmed up to the set value. After a defined follow-up time, the lighting is softly dimmed down again to the level of the orientation light.
Comfort and safety – two aspects a KNX motion detector must cover. Nothing accomplishes these tasks better than theLuxa P300 KNX. Integrated in the KNX building system technology, it detects exactly , when it should guide the way.
Especially in larger areas, it is about detecting and automatically responding to streams of movements which have to be expected. For instance of employees, who enter the company premises in the early morning, and often leave late in the evening. Or employees and visitors of hotels, hospitals and administrative buildings. In all these cases, it is about the required control, but also a predictive lighting of entrance halls, access routes and connecting passages.
theLuxa P300 KNX (protection class IP 55) is available in white or black, and can be installed on the wall or ceiling, thanks to its swivelling sensor head. With a 300° detection area of up to 16 m, and creep under protection, theLuxa P300 KNX does not miss anything. Via ETS, the motion detector can be easily integrated into the building automation, and it is easy to configure. Brightness thresholds, duty cycle, and sensitivity can easily be configured via the KNX visualisation.
Thanks to its swivelling sensor head, theLuxa P300 KNX is not only suitable for wall mounting but also for ceiling mounting. The motion detector and its included accessories (corner bracket, spacer frame) are available in white and black.
The four motion detector channels can be linked in a timedependent manner for various lighting applications, such as switching or dimming, for instance as an orientation light. Functions, such as short-time presence, master/slave, fully automatic/semi automatic device and two switchable time delays can be configured via ETS.
The four universal channels respond, independent of movement, to temperature and/or brightness, and can thus be used as a twilight switch, for instance.
The "AND", "OR", and "XOR" operations of the four independent logic channels respond to current bus events. As initial object, switch commands, or percentage values can be sent, for example.
theLuxa P300 KNX is an enrichment to any scene. The motion channel can be incorporated into scenes in a number of versatile ways: "locking", "permanent ON", "brightness threshold", and "change over time delay".
Functions, such as "locking", "permanent ON", "brightness threshold", and "change over time delay" can be called up in a time-dependent manner via the integrated time switch function with a simple weekly program.
theLuxa P300 KNX has an integrated temperature sensor, which can be used for temperature-dependent operations.
theLuxa P300 KNX supports remote operation. 2 scenes and numerous settings can be easily made from the ground. This is faster, shortens the installation time and lowers costs. And, it is safer.
Lighting conditions change quickly - it is good if you can simply save them when they are exactly how you want them to be. With the clever teach-in function, the current lux value can be permanently saved.
