iPower GLFANXINLINEPRO6 6 Inch 390 CFM Inline Duct Temperature Humidity Variable Speed Controller, Quiet HVAC Ventilation Exhaust Blower Fan, 6", White

I was looking for a quiet high CFM fan with temperature and humidity sensors. The iPower looked like a good choice, but now it runs only at 100% all the time after intermittent use for a few months. The control unit lights up, but it reports a fan error via a bell icon. Disconnecting and re-connecting the control unit has no effect. Disappointing to have spent hundreds of dollars on a fan that won't respond to environmental sensors. If anyone finds a better solution, please let me know.

Works great easy to install

Overall a great system.
