The switch's main appeal is its combined humidity-triggered fan control and motion-activated light timer, which aims to reduce excess moisture without manual intervention. For bathrooms, laundry rooms or basements where humidity and intermittent occupancy matter, this switch automates ventilation and lighting while offering simple override options and three humidity set points.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHumidity-triggered fan:\u003c\/strong\u003e Automatically turns the ventilation fan on when moisture exceeds the chosen set point to help prevent excess humidity and related problems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree sensitivity levels:\u003c\/strong\u003e Low, medium, and high humidity thresholds let the user match ventilation to the room's needs for more precise control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePIR motion lighting:\u003c\/strong\u003e Passive infrared motion sensor activates lights on detection with an adjustable timer to reduce wasted lighting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManual override options:\u003c\/strong\u003e A manual ON\/OFF light switch bypasses the timer and a separate switch can bypass the humidity sensor for direct fan control when needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation and safety:\u003c\/strong\u003e Requires a neutral wire and is UL Listed for safe use in typical 120VAC residential circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable time delay:\u003c\/strong\u003e Time delay for the light can be set between 5 and 30 minutes to suit occupant preference and energy savings.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe switch is best suited to homeowners or renters with access to a neutral wire who want an integrated solution for fan and light automation in bathrooms, laundry rooms, basements, or other high humidity areas.
