Panasonic FV-CSVK1 WhisperGreen Select Condensation Sensor Module – Plug N Play Humidity Control – 1-Pack – New in Box

Stop Bathroom Condensation Before It Starts — Automatically

Manual bathroom exhaust fans get forgotten. The result is fogged mirrors, damp walls, and the slow creep of mold and mildew in corners you can't easily reach. The Panasonic FV-CSVK1 WhisperGreen Select Condensation Sensor Module eliminates that problem by reading both relative humidity and temperature to anticipate dew point conditions — automatically activating or boosting your fan's speed before condensation can form. No wall switch required. No guesswork. Just clean, dry air managed quietly in the background. Available here at More4less Outlet as a brand-new, in-box unit — also found in our Home & Living and Electronics & Gadgets collections.

Features & Benefits

• Predictive Sensor Technology: Reads both relative humidity (RH) and temperature simultaneously to anticipate dew point conditions — activating the fan before condensation forms rather than reacting after the fact.
• Built-In 20-Minute Delay-Off Timer: Once humidity levels drop to the set threshold, an automatic 20-minute timer runs the fan just long enough to fully clear residual moisture — then shuts off without any manual input.
• Snap-In Plug N Play Setup: Installs directly inside the WhisperGreen Select fan housing in minutes. No complex wiring, no additional components. Snap in, adjust the dial, done.
• Adjustable Sensitivity Dial: Built-in RH sensitivity adjustment lets you fine-tune the trigger point to match your local climate, bathroom size, or code requirements.
• Code-Compliant Ventilation: Helps satisfy CALGreen and ASHRAE 62.2 continuous ventilation requirements — a practical asset for new construction, remodels, and permitted work.

Frequently Asked Questions

Q: Will this module work with any bathroom exhaust fan?
A: No. The FV-CSVK1 is designed exclusively for Panasonic WhisperGreen Select models: FV-05-11VK1, FV-05-11VKS1, FV-05-11VKSL1, FV-05-11VKL1, FV-11-15VK1, and FV-11-15VKL1. Verify your fan model before purchasing.

Q: Do I need an electrician to install this?
A: The snap-in Plug N Play design is intended to simplify installation inside the existing fan housing. However, always turn off power at the breaker before accessing any electrical fixture. If you are not comfortable working with electrical components, consult a licensed electrician.

Q: What does the sensitivity dial adjust?
A: The built-in RH sensitivity dial lets you set the relative humidity threshold at which the sensor activates the fan. This allows you to fine-tune the response based on your bathroom size, local climate, or ventilation code requirements.

Q: How long does the fan run after humidity drops?
A: Once the sensor detects that humidity has dropped to the set threshold, an automatic 20-minute delay-off timer activates — running the fan long enough to clear residual moisture before shutting off.

Q: Is this product code-compliant?
A: Yes. The FV-CSVK1 helps satisfy CALGreen and ASHRAE 62.2 continuous ventilation requirements when used with a compatible WhisperGreen Select fan.
