Panasonic FV-WCD01-A is a countdown and hourly timer designed to give you full control over the ventilation of your bathroom, laundry room, sun room, or spa room. It features two timers in one: a countdown timer and a fresh home / Minutes Per Hour (MPH) timer, which work together to ensure optimal indoor air quality.

The countdown timer can be set anywhere from 5 to 80 minutes, and it activates any time you manually turn the fan on.
