Presence detector Gira Präsenzmelder Mini Komfort KNX 222500 — ceiling-mounted KNX presence sensor for automatic lighting and HVAC control

The Gira Präsenzmelder Mini Komfort KNX 222500 is a compact ceiling-mounted presence detector designed for integration with KNX building automation systems. Intended for reliable detection of presence and motion, it enables automated control of lighting and HVAC circuits. The device supports adjustable detection zones and sensitivity settings via KNX parameters, making it suitable for a variety of interior spaces where occupancy-based control improves comfort and energy efficiency.

Advantages

The presence detector offers a small footprint for discreet ceiling installation and seamless integration with KNX networks. It provides configurable detection areas and sensitivity levels through the KNX bus, allowing tailored responses to different room geometries and use patterns. By detecting presence and motion, the sensor facilitates automated switching and timed control of lighting and climate systems, contributing to reduced energy consumption and consistent environmental control.

Key specifications

How to use

Install the presence detector on the ceiling at the recommended central position for the monitored area, following local electrical codes and KNX installation practices. Connect the device to the KNX bus and configure detection zones, sensitivity, and time-delays using the KNX commissioning tool. Program desired actions for lighting and HVAC control within the KNX system so that presence and motion events trigger the appropriate scenes or outputs. Verify coverage and adjust parameters remotely via KNX during commissioning to avoid false triggers or missed detections.

Recommendations

Position the sensor to minimize direct exposure to large windows or heating sources that may affect detection. Test and fine-tune sensitivity and time settings during different occupancy conditions to balance responsiveness and energy savings. Use appropriate KNX group addresses and scenes to coordinate the presence detector with lighting and climate control devices for smooth operation.
