Details
Introducing Lutron’s first-ever Humidity Sensor Switch, offering a bathroom solution that you and your homeowners can be proud of. This state-of-the-art device detects humidity levels to activate the exhaust fan when needed, reducing moisture, mildew, and mold in any bathroom space. The device is compatible with a 3 A, 1/10 HP fan, as well as a 3 A combined fan and light. Showcasing our commitment to quality and innovation, the XACT Sense Humidity Sensor Switch measures humidity levels and uses advanced signal processing to determine the optimal time to activate the fan. This new humidity-sensing feature provides added convenience and allows consumers to adjust how long the fan will stay on once activated.
