Microwave presence detector capable of detecting motion, evaluating the ambient light level, and transmitting information to other system devices such as dimmers, relays, etc. via the common KNX bus. Built-in sensors allow measurement of ambient light, temperature, and humidity in the room. The detector is intended for ceiling mounting at a height of up to 4 meters, with a motion detection diameter of up to 8 meters. Sensitivity can be configured and adjusted depending on day/night conditions. The built-in thermostat (2-point and PID control) enables management of heating and/or cooling systems. Up to 4 groups of lighting control algorithms with a wide range of actions in each, including Master-Slave mode, allowing multiple detectors to be combined into a single group. A wide range of logical functions. KNX Secure support. Supports the standard KNX protocol and is compatible with certified KNX equipment from major global manufacturers. Power supply: 12–30V DC. Overall dimensions: Ø65×38 mm (flush-mounting part: Ø48.5×38 mm).
