Occupancy sensor Steinel True Presence Multisensor KNX flush-mounted, black

Steinel True Presence Multisensor KNX flush-mounted in black is a compact occupancy and presence detector designed for integration into KNX building automation systems. The device combines fine motion and presence detection in a discreet, recessed housing that blends into ceilings or panels. It provides reliable detection of stationary and moving occupants to control lighting and HVAC via the KNX bus, making it suitable for professional applications in offices, meeting rooms, corridors and other indoor areas where accurate presence sensing is required.

Advantages

The sensor offers accurate presence detection even for low-movement activities thanks to its high-sensitivity technology. Its flush-mounted format ensures a low visual profile and protects the sensor from accidental contact. Integration with KNX allows centralized control and configuration through the building automation system, enabling coordinated management of lighting and climate. The black finish provides a neutral appearance in contemporary interiors and reduces visual contrast in darker ceilings.

Suitable for

• Open-plan and private offices for energy-efficient lighting control
• Meeting and conference rooms where detection of stationary occupants is needed
• Corridors, stairwells and circulation areas requiring automated lighting
• Smart building installations with KNX-based lighting and HVAC integration

Key specifications

• Type: Flush-mounted occupancy and presence multisensor
• Detection modes: Motion detection and presence detection for stationary persons
• Integration: KNX bus-compatible for system-level control and configuration
• Installation: Recessed mounting suitable for ceilings or panels
• Housing color and finish: Black, low-profile design
• Typical application environment: Indoor commercial and office spaces

How to use

Install the sensor into a compatible recessed mounting box or ceiling opening at the recommended height and position for the monitored area. Connect the device to the KNX bus according to the KNX wiring and commissioning guidelines and configure detection parameters and switching logic via the KNX engineering tool. Adjust sensitivity and presence settings during commissioning to match room layout and typical occupant behavior to avoid false triggers and ensure reliable control of lighting and HVAC functions.

Usage recommendations

Position the sensor to provide an unobstructed view of the occupied zone and avoid mounting near large heat sources or ventilation outlets that may affect presence detection. Fine-tune presence sensitivity for rooms with long periods of low movement, such as meeting rooms, to ensure both comfort and energy efficiency within the KNX-controlled system.
