Panasonic-Multi-Speed with Time Delay
The multi-speed module comes standard in models FV-05-11VKS1 and FV-05-11VKSL1. It can be added to the other models, leaving you with two remaining slots for the condensation sensor, motion sensor or night light.
The multi-speed with time delay module lets you select the proper CFM setting. The fan runs continuously at a pre-set lower level, then increases to a maximum level 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 pre-set period of time.
