Introducing Lutron's latest sensing technology, the Maestro Dual Technology sensor enhances reliability by using both passive infrared and ultrasound technology to ensure optimal sensing performance for small rooms. Lutron's XCT Dual Technology detects very fine motion, such as typing at a desk or reading, ensuring lights do not turn off inadvertently. To save additional energy, enable ambient light detection, which allows the sensor to learn your light level preference over time and adapt accordingly to keep lights off when there is enough daylight in the room. Maestro Sensors work with any bulb type, including CFLs and LEDs and will match the decor of any room in your home. Works with 6 Amps lighting/4. 4 Amps fan in single pole applications. Installing and setting up a Maestro in-wall, dual-technology occupancy sensor is a simple, easy and low cost way to save energy and add light automation to your home.
