This fan is designed to run continuously ensuring a healthy climate at low CFM levels 24 hours a day. NOTE: This NEW model can also be configured for spot (non-continuous) ventilation!!This fan is also built to take care of the homeowners spot ventilation needs when the room is occupied. This fan kicks-up to a maximum level of 130 CFM when activated by standard switch. A High/Low Delay Timer, located inside the fan unit, is utilized to return the fan back to the pre-set continuous ventilation mode OR shut off completely
A NOTE ON SWITCHING THIS FAN:
There are a variety of ways that this fan can be switched. When contact with the high speed (red) wire is opened - the countdown begins to turn the fan down to the continuous operation (low) speed. As the wiring diagram indicates - it is also possible to introduce an additional switch to override the fan and turn it off altogether. We have made a special "momentary contact" switch available to make the transition from low to high speed easy.
Constant CFM Performance
This WhisperGreenT model features built-in intelligence called SmartFlowT Optimum CFM Technology. This unique "electronic-brain" lets the fan do what was once thought to be impossible, perform at a constant CFM regardless of elbows and other factors that might hinder performance. Basically, when a WhisperGreenT fan faces static pressure, its speed is automatically increased to ensure that the desired CFM is actually achieved. This allows the fan to perform as rated and makes for easier installation because the installer no longer has to worry as much about compromising the fan's performance. Uses ultra energy-efficient DC motor.
DC Brushless Motor
Panasonic's DC brushless motor provides unparalleled energy efficiency with its magnetic rotor and print circuit board. The magnetic rotor prevents energy loss while the print circuit board incorporates a unique IC chip which monitors and directs the RPM of the fan blade. The combination of these two unique features allows the DC motor to have higher energy efficiency than an AC motor.
Variable Speed Control
This fan is equipped with a CustomVentT Variable Speed Control. This allows the fan to run continuously at a pre-set lower level of 50-130 CFMs that can then be elevated to a maximum of 130 CFMs when the switch is turned on. A High/Low delay timer(adjustable from 30 seconds - 60 minutes), will then return the fan to the minimum CFM level after a period of time set by the user.
