Panasonic WhisperSense-Lite Collection

This WhisperSense-Liteā„¢ model features Exclusive Dual Sensor Technology reacts to both motion and humidity, automatically turning the fan on when needed. No effort is required.... the fan does all the work for you. No more forgetting to turn the fan on with Panasonic's decision free technology. A built-in humidity sensor detects rapid rise in relative humidity (RH), automatically turning on the fan to remove moisture and helping to prevent mold and mildew. Built-in adjustable delay timer can be set from 30 seconds to 60 minutes and activates when motion is no longer detected or when humidity levels are below preset levels. Already remarkably energy efficient, our auto shut off feature can help eliminate unnecessary energy use and further reduce operating costs.
