The new WhisperGreen Select Bathroom Fans from Panasonic offer a customizable ventilation solution that is energy efficient and feature-rich.  The FV-05-11VKS1 base model provides a single fan which can be customized or used as is - with the choice of 50, 80, or 110 CFM.  The Pick-A-Flow speed selector allows you to change the CFM rating on-the-fly.   The FV-05-11VKS1 includes a built-in multispeed selector for continuous, low volume ventilation with configurable time delay after boost. This feature set provides a way to run the fan at lower speeds to maintain ventilation standards to meet indoor air quality (IAQ) and then boost up to high speed for "spot ventilation" when moisture or odor is present.  The multi-speed module offers adjustable dials to configure appropriate level of lowspeed airflow (CFM) and a time delay for return to the low speed after the boost.
The WhisperGreen Select fans are built using DC motor technology.  The DC motor is 30-70% more energy efficient than the minimum ENERGYSTAR requirements. The WhisperGreen Select fans are the most technologically advanced and energy efficient products available!

This fan can accept up to 2 Plug 'N Play Modules, which are described below

SmartAction Motion Sensor Module - FV-MSVK1 - Turns the fan on or boosts to a higher speed when motion is detected.  The motion sensor is pre-set to run the fan for 20 minutes; it will then re-check for movement; if detected the fan will run for another 20 minute cycle.

Condensation Sensor Module - FV-CSVK1 - Turns the fan on or boosts to a higher speed when conditions for condensation are detected.  The condensation sensor works based on calculations from the psychrometric chart - or combination of relative humidity (RH) and temperature.  This allows the fan to anticipate the formation of condensation and automatically turn on when needed to expel humid air.  The condensation is pre-set to run for 20 minutes; it will then check the RH and temperature to detect if the fan needs to run for another 20 minute cycle.

NiteGlo LED Night Light Module - FV-NLVK1 - automatically turns on with ambient light levels are met.  Turning the dial on the module to "DARK" is ideal if the fan is in an isolated room with little ambient light from nearby rooms.  Turning the dial to "BRIGHT" is ideal if there is light spill from adjacent rooms.  This module is only recommended when using in conjunction with other modules or when power is being run directly to the fan and the red control loop wires are being used to turn on the fan.
