## Summary description

Steinel US 360 KNX V3.1 is a recessed presence and twilight sensor designed for KNX installations. It combines motion detection and ambient light measurement to automate lighting control based on presence and daylight. The square, white IP20 device integrates into ceilings or walls and supports KNX communication for centralized smart-building management.

## Long description

Steinel US 360 KNX V3.1 recessed presence and twilight sensor is designed for KNX-based building automation. The device combines passive infrared motion detection with an ambient light sensor to control lighting circuits according to occupancy and daylight levels. Its square white housing is intended for flush mounting in ceilings or walls and is rated IP20 for indoor use. The sensor supports KNX communication for integration with central control systems and scene logic.
Advantages
The sensor offers combined presence detection and twilight measurement in a compact, square design suitable for discreet flush installation. Integration with KNX allows centralized configuration and the use of building automation topology for reliable switching and dimming. Adjustable detection parameters and light-level thresholds enable customized behavior for different rooms and applications. The IP20 rating and white finish make it appropriate for most interior installations where protection against solids is sufficient.
Suitable for
Interior rooms in commercial or residential buildings with KNX automation
Corridors, stairwells, and utility rooms where presence-based lighting is required
Offices, meeting rooms and reception areas that benefit from daylight-dependent control
Ceiling or wall locations where flush-mounted square sensors are preferred for aesthetics
When it may not be suitable
This sensor is intended for indoor environments only and is not rated for wet or outdoor locations due to its IP20 protection class. It is designed specifically for KNX systems and therefore requires KNX installation and configuration; it will not operate as a standalone wireless or conventional hardwired presence sensor without KNX infrastructure. For environments requiring higher ingress protection, rugged housings, or non-KNX standalone solutions, alternative products should be considered.
Key specifications
Detection technology: passive infrared (PIR) motion detection combined with ambient light measurement
Mounting: recessed (flush) ceiling or wall mount, square form factor
Protection rating: IP20 suitable for indoor use
Color and finish: white
Communication: KNX-compatible for integration in building automation
Adjustable parameters: detection sensitivity, hold time and twilight threshold settings via KNX
How to use
Install the sensor into a compatible recessed mounting box in the ceiling or wall, ensuring correct orientation for the monitored area. Connect the device to the KNX bus and configure parameters such as detection zones, sensitivity, hold times, and ambient light thresholds through the KNX commissioning tools. Use KNX group addresses to link the sensor to lighting actuators, scenes, and timers. Verify detection coverage and adjust angle or sensitivity settings as needed to avoid false triggers from nearby heat sources or reflections.
What to consider before purchase
Required KNX infrastructure and commissioning tools for configuration
Indoor use only — check IP20 is suitable for the installation environment
Mounting depth and cutout dimensions for recessed installation
Compatibility with existing lighting actuators and KNX topology
Usage recommendations
Position the sensor centrally for uniform coverage, and configure daylight thresholds to prevent unnecessary switching when ambient light is sufficient. During commissioning, perform walk tests and adjust sensitivity and hold times to balance responsiveness and prevent false positives.
