4-Hour Countdown Timer Switch, Neutral Required

4 Hour Countdown Timer Switch provides a high-performance solution for automating lighting and ventilation systems to maximize energy efficiency. This 120VAC electronic timer offers six preset countdown intervals—5, 10, 30, and 60 minutes, plus 2 and 4 hours—allowing users to tailor the operation of bathroom exhaust fans, heaters, and ceiling fans to their specific needs. By automatically turning off loads in unoccupied rooms, this switch provides a 100% satisfaction-guaranteed way to reduce utility waste and modernize your home's electrical system. A standout feature of this model is its dual-mode LED indicator: in Mode 1, the blue LED flashes twice, then turns off for use in a dark bedroom. In contrast, Mode 2 keeps the LED on during the countdown to serve as a status indicator. The switch supports heavy-duty loads, including 1200W Tungsten Lamps and 1/2 HP motors, making it suitable for powerful ventilation fans. Requiring a neutral wire for a stable, long-lasting electrical connection, this UL-listed switch includes a premium screwless wall plate for a clean, professional finish that hides mounting screws from view.
