The Somfy Soliris RTS Sun-Wind Sensor (24V) enhances your motorized awning by automatically retracting the awning in high winds, and automatically opening it when intense sunlight is detected. You can set the wind threshold (6 to 31 mph) and sunlight threshold (0 to 50 kilolux) directly at the sensor for personalized use. The sensor is compatible with Somfys LT RTS CMO and ALTUS RTS motors, and is powered by an included class 2 transformer. NOTE: Compatible with RTS (Radio Technology Somfy) motors ONLY. RTS motors are remote controlled Somfy motors. This product is not compatible with any non-remote controlled motor.
