Frequently Asked Questions
What devices can I control with FV-WCCS2-W?
This model controls both a ventilation fan and an overhead light, with independent manual control for the light and automated moisture control for the fan.
How does the condensation sensor work?
It uses humidity and temperature to anticipate dew point. Once condensation is likely, it triggers the fan automatically and then turns it off after 30 minutes once humidity returns to normal.
Can I manually turn the fan or light on?
Yes. Manual ON activates a 20-minute fan timer, and the light can be toggled independently on or off.
What does the MPH timer do?
It runs the fan for a user-set amount of time every hour (0–60 minutes), helping comply with ASHRAE 62.2 ventilation standards.
Is the moisture sensitivity adjustable?
Yes. Choose from High (dry climates), Average (default), or Low (humid regions) to best suit your environment.
What fans is this compatible with?
It’s optimized for Panasonic Whisper-series fans and extends the warranty of certain models when used together.
Can this be used in wet locations?
No. This device is for indoor use only and should not be exposed directly to water.
