Panasonic FV-WCD01-W WhisperControl Countdown & Hourly Timer – Pre-Set Countdown | Adjustable Fan Timer | ASHRAE 62.2 Compliant Enhance your home’s ventilation strategy with the Panasonic FV-WCD01-W WhisperControl Countdown and Hourly Timer. This versatile wall control allows you to pre-set your ventilation fan to operate automatically for a selected period or at regular intervals—delivering cleaner air, improved efficiency, and code-compliant performance in residential and multi-tenant spaces. Dual Timer Functionality for Complete Control This smart controller combines a pre-set countdown timer (5 to 60 minutes) with an Adjustable Minutes Per Hour (MPH) fan timer. The countdown timer lets you manually turn the fan on, then automatically shuts it off after the selected duration—perfect for bathrooms, kitchens, or tenant-use areas. Meanwhile, the MPH function enables users to set the fan to run for a defined period every hour (0–60 minutes), supporting continuous ventilation as required by ASHRAE 62.2, LEED, and ENERGY STAR® 3.1 guidelines. It even senses when the countdown timer has been used and pauses hourly cycling to prevent over-ventilation. Manual Fan Control LED Indicator For immediate airflow, simply press the manual on/off button. A built-in blue LED indicator lights up when the fan is operating, providing a simple visual cue. Engineered for Performance and Durability Built to commercial-grade standards, the FV-WCD01-W supports up to 8 amps of load, making it ideal for handling LED lighting and DC motor fans. The unit includes a stylish white wall plate and is backed by a two-year limited warranty. Why Choose the FV-WCD01-W WhisperControl Timer?
