Leviton’s White Humidity Sensor & Fan Control Switch brings intelligent moisture management to any bathroom or damp-area installation. This single-pole retrofit replaces a standard wall switch, automatically sensing excess humidity and activating your ventilation fan to help prevent mold and mildew. User-friendly dials let you fine-tune both the humidity-trip level and fan run-on timer, delivering balanced airflow exactly when you need it—no manual toggling required.

Built to Leviton’s high standards, the RO2-IPHS5-0LW model accommodates a variety of lighting and fan loads while fitting seamlessly behind most standard wall plates. Whether you’re upgrading an existing switch or specifying new construction, this white humidity control switch offers reliability, flexibility, and discreet design for modern homes and commercial spaces.
