• Smart Temperature & Humidity Controller: The intuitive controller lets you switch between ON / OFF / TIMER / AUTO modes with ease. AUTO mode automatically starts or stops the fan based on your set temperature and humidity thresholds (High/Low Temperature; High/Low Humidity), complete with an auto-alarm function.
