Panasonic WhisperGreen Select Multi-Speed Module with Time Delay

Panasonic WhisperGreen Select Multi-Speed Module with Time Delay. Allows you to select the proper CFM settings to satisfy ASHRAE 62.2 continuous ventilation requirements. The fan runs continuously at a pre-set lower level, then elevates to a maximum level of operation when the wall switch is turned on, or when the SmartAction® motion sensor or condensation sensor module is activated. A high/Low delay timer returns the fan to the pre-set CFM level after a period of time set by the user. Plug-n-play module for Panasonic WhisperGreen Select ventilation systems.
