You want light and climate to react automatically without the room looking cluttered with technology. This white KNX ceiling presence detector combines reliable PIR detection with brightness measurement as well as temperature, humidity and CO2 in one device, so that automations and controls can work directly from real room values.



  • 360° detection with four sectors: The presence detector function works with PIR technology in four separate detection sectors with adjustable sensitivity, allowing the response to be tailored specifically to walkways, work areas and sources of interference.
  • Large motion range up to Ø 30 m: For a mounting height of 2.7 m, tangential motion detection reaches up to Ø 30 m and radial up to Ø 20 m, at 4 m mounting height it is up to Ø 25 m tangential and Ø 16 m radial, while the presence zone is at Ø 10 m.
  • Constant light and switching thresholds: Two channels for constant light control and several configurable presence channels enable either brightness control, switching based on brightness threshold, or pure presence logic without light value dependency.
  • Multisensor including CO2 control module: The device measures temperature, relative humidity and CO2 internally and additionally provides a CO2 controller module so that ventilation and air quality can be controlled directly based on ppm values.
  • KNX-TP with KNX Data Secure: As a KNX-TP1-256 device, it communicates directly on the bus and supports KNX Data Secure, which secures telegrams against manipulation and eavesdropping in suitable projects.
  • 2 analogue or digital inputs: Two inputs (dry contacts) with 3.3 V DC at common and up to 30 m cable length allow additional sensors such as switches, contacts or temperature sensors to be integrated into one device.


Detection and reporting functions

As a white KNX presence detector for ceiling mounting, the device covers 360° and divides detection into four sectors, whose sensitivity can be adjusted separately, which offers real advantages in open floor plans or rooms with clearly defined zones such as workspaces, walkways and door areas. For planning, the detection ranges depend on the mounting height: At 2.7 m height, the motion detection area for tangential movement is Ø 30 m and for radial movement Ø 20 m; at 4 m height, this reduces to Ø 25 m tangential and Ø 16 m radial, because radial movements towards the sensor axis are generally harder to detect than tangential ones. For true presence detection in terms of small movements, the presence zone is specified as Ø 10 m; additionally, there is a maximum detection zone of Ø 6 m that is not affected by the sensitivity configuration, which is helpful for robust basic detection directly under the detector. Six presence detector channels are available in the parameterisation, allowing multiple logics to be mapped in parallel, for example separate messages for lighting, shading, alarm or HVAC, without everything having to be linked to a single presence object. For more complex logic, ten logic functions are integrated, so that links, time conditions or simple evaluations can be implemented directly in the device if you want to reduce bus load or bring logic closer to the sensor.

Sensors for climate and air quality

Beyond mere presence, the multisensor provides internal measurements that are often crucial in KNX projects because they make automations more stable and can save additional individual devices. The temperature sensor measures from -10 °C to 60 °C with 0.1 °C resolution and has an accuracy of ±0.8 °C at 25 °C, which is typically sufficient for room control and temperature monitoring in residential and commercial buildings. Humidity measurement covers 0 to 100 % RH, works with 1 % resolution and ±6 % RH accuracy, has a response time of 1 s and a drift of ±0.25 % per year in normal air, allowing humidity monitoring and ventilation-based logic such as dehumidification requirements or mould prevention to be reliably implemented. The CO2 sensor measures in the range of 400 to 2000 ppm with 10 ppm resolution and ±50 ppm accuracy as well as a drift of ±5 ppm over five years, enabling air quality indicators, ventilation stages or demand-based controls based on ppm thresholds; for correct measurements, the room must be ventilated at least once a week because the sensor needs fresh outside air for referencing. In practice, this means that when planning threshold values, it is sensible to include minimum ventilation logic alongside comfort thresholds so that the system does not only react to load peaks but measurement values remain stable in the long term.

Connection and KNX integration

The device operates fully via the KNX bus and requires no external power supply, simplifying installation and making it easy to calculate typical line dimensions. The supply is typically 29 V DC SELV, the permissible range is 21 to 31 V DC, and the maximum current consumption is 8.4 mA at 29 V DC or 10 mA at 24 V DC, allowing you to accurately include line load in power supply planning. Connection to the bus is via the usual TP1 bus connector for 0.8 mm solid conductors, and the integrated KNX BCU (TP1-256) ensures direct, standard-compliant bus communication. For commissioning and service, there is a programming button and programming LED, with the display also indicating states such as initialisation of the motion sensors and visualising sector detection via short light pulses, which helps with zone alignment during shell construction or changes in the usage concept. The two analogue or digital inputs are designed as dry contact inputs and operate with 3.3 V DC at common, input current is 1 mA per input, the terminals are screw terminals up to 0.2 Nm, conductor cross-section is 0.5 to 1 mm² and maximum cable length is 30 m, making it practical to connect contacts, switches or compatible temperature sensors nearby without adding extra bus devices.

Planning and installation

For mechanical planning, the design, installation type and environmental conditions are decisive because presence detectors strongly depend on position and surroundings. The housing measures Ø 84 x 47 mm and weighs 66 g, the protection rating is IP20 for clean indoor environments, and the permissible operating range is 0 to +35 °C and 5 to 95 % humidity. Installation is possible as flush-mounted or surface-mounted, allowing the device to be installed in suspended ceilings, concrete ceilings or even situations without a suitable flush-mounted box without changing functionality. The four detection sectors help with positioning because by adjusting orientation and individual sensitivity, you can specifically avoid movements outside the useful area, for example in adjacent corridors or at glass surfaces, triggering unnecessary telegrams. For lighting automation, the combination of presence and brightness is particularly relevant: Two constant light channels are suitable for work areas with changing daylight, while switching logic based on brightness threshold is better suited if only a simple on-off reaction is desired, and pure presence logic remains sensible if the light value is too strongly influenced by other sensors or the position of the luminaires. For HVAC applications, the interplay of temperature, humidity and CO2 helps because it allows not only heating and cooling but also ventilation and comfort logic to be controlled according to actual use and air quality, without separate sensors needing to be installed in visible areas.

Manufacturer

Zennio develops KNX devices that often combine sensors, logic and operation in compact designs to make installations with fewer individual components easier to plan. The brand places great importance on fine parameterisation, for example in sensitivities, calibrations and channel divisions, which facilitates adaptation to room geometry and usage in large projects. A recurring focus is on integrated logic functions and multi-channel concepts so that typical automation tasks can be implemented close to the bus. With support for KNX Data Secure, Zennio also addresses projects where communication and access protection in building technology are given greater priority.
