MDT KNX aanwezigheidsmelder 2,2 m TS 55, PSE-B552T02.02S

Detect presence across a 95 m² area with 360° coverage from a single flush-mounted device. The MDT KNX Presence Detector PSE-B552T02.02S integrates six sensors—presence, light, temperature, humidity, air pressure, and CO2—into one TS 55-compatible unit.

Overview

Designed for ceiling installation at a height of 2.2 m, this KNX presence detector monitors a circular zone approximately 11 m in diameter. It operates directly on the KNX bus (21-30 V DC) and consumes only 0.2 W. The integrated push button allows manual control or teach-in, while the LED provides local status indication.

What stands out

• Six built-in sensors eliminate the need for separate environmental monitors.
• Eight logic gates enable complex automation without extra modules.
• Constant light control and HVAC functions support energy-efficient building management.
• Flush-mounted design fits standard TS 55 switch ranges from Gira, Jung, Berker, and others.
