Multi-Sensor

Designed to enhance comfort and energy efficiency in modern living spaces, the OPT-MSx-21y series are KNX-compatible indoor detectors. With advanced motion and presence detection capabilities, they automatically control lighting and HVAC systems, improving user comfort and enabling energy savings. Powered directly from the KNX bus, they eliminate the need for external power and simplify installation.

The device continuously monitors ambient conditions using built-in brightness, temperature, humidity, and optional air quality sensors, and transmits the data to the KNX network for more efficient smart building operation. Constant light level control allows lighting to be automatically adjusted based on daylight, ensuring both savings and optimal lighting conditions.

With its Room Temperature Controller (RTC) functionality, temperature measurements are managed directly via KNX to optimize heating and cooling systems. Additionally, the device can be expanded with digital input and I/O modules and supports complex automation scenarios through advanced logic functions. Available in both flush-mounted and surface-mounted versions, it adapts to various architectural needs.
