Multi-Speed Module With Time Delay | FV-VS15VK1

The Multi-Speed Module With Time Delay (Part Number: FV-VS15VK1) is a high-performance accessory that enhances your ventilation system by providing precise control over airflow. This module features a High/Low Delay Timer, allowing you to select the optimal CFM settings to meet ASHRAE 62.2 continuous ventilation requirements. It operates by running the fan continuously at a lower level and ramps up to maximum operation when triggered by a wall switch, SmartAction® motion sensor, or condensation sensor module. The built-in high/low delay timer automatically returns the fan to the preset CFM level after a user-set period.
