Functions Temperature measurement The room unit measures temperature using a digital temperature and humidity sensor. Relative humidity measurement The room unit measures relative humidity using a digital temperature and humidity sensor. Indoor air quality indication The room unit indicates CO 2 levels using a traffic light LED: Green (ok), orange (fair), red (bad). Low-power operation With advanced algorithms and parameters, the room unit reduces measurement and communication frequency, achieving long sleep cycles and a battery life of upto 10 years. Firmware update The device supports over-the-air (OTA) firmware update. The device can be updated to the latest firmware version during commissioning. Smart linking The device supports smart linking, which allows for the automatic linking of group objects through a simple drag-and-drop action on smart linking channels. Cybersecurity Implements end-to-end encryption and authentication for all KNX IoT communications. All telegrams are digitally signed and encrypted, ensuring data integrity and confidentiality. Security mechanisms apply to both ETS-based commissioning and runtime communication between devices and visualizations. Mechanical design The Wireless Room Unit is designed for wall, flush, and tape mounting. It is compatible with most standard recessed conduit boxes available on the market. The device consists of two parts: ● Front part including electronics ● Mounting plate 3 SiemensA6V15019166_en--_a Smart Infrastructure2025-10-24 Type summary Product No.Stock No. Temperature measuring range Humidity measuring range BatteriesOutput signal QMA340KT S55627-H101 0...50 °C 5...95 %4 × 1.5 V AAA alkaline KNX IoT via Thread Delivery When ordering, specify name and product number, e.g.: Wireless Room Unit QMA340KT.
