Motion sensor Steinel HF 3360 KNX V3 UP square — Steinel HF 3360 KNX V3 UP

Steinel HF 3360 KNX V3 UP square is a recessed KNX motion sensor that uses high-frequency (HF) detection to register presence and movement for lighting control in KNX installations. Designed for flush mounting in ceilings or walls, the sensor provides reliable detection in offices, corridors and commercial spaces where discreet installation and KNX integration are required. The device communicates with KNX systems to trigger lighting and automation functions based on presence and motion data.

Advantages

The sensor’s HF detection ensures accurate presence detection including small movements and stationary occupants, enabling energy-efficient control of lighting and building automation. Recessed square design offers a low-visibility installation that integrates with suspended ceilings or plaster surfaces. KNX compatibility allows centralized configuration and flexible scene or time-based control within building management systems.

Suitable for

• Office rooms and open-plan workspaces
• Corridors, stairwells and circulation areas
• Meeting rooms and conference areas with intermittent occupancy
• Commercial retail and service areas requiring integrated KNX control

Key specifications

• Detection technology: high-frequency (HF) presence and motion detection
• Mounting type: recessed / flush mounting for ceiling or wall
• Shape: square design suitable for grid and plaster ceilings
• Communication: KNX protocol integration for building automation
• Typical applications: presence detection, lighting automation, energy-saving control

How to use

Install the sensor in a recessed mounting box or ceiling cavity at the recommended height and position for the monitored area. Connect the sensor to the KNX bus following the system wiring rules and assign group addresses for presence, absence and lighting control. Calibrate detection parameters and time delays via the KNX configuration tool to match the use pattern of the room. After configuration, the sensor reports presence and motion events to the KNX system to control lighting and automation scenes.

Usage recommendations

Position the sensor to avoid direct exposure to HVAC outlets or reflective surfaces that may affect HF detection. Use parameter settings in the KNX configuration to adjust sensitivity and hold times for different room types; lower sensitivity can reduce false triggers in high-traffic areas, while longer hold times can prevent frequent switching in meeting rooms. Regularly verify KNX group addresses and firmware compatibility when integrating into existing building automation systems.
