Big Ass Fan's Automatic Destratification System keeps temperatures consistent through all seasons
The Automatic Destratification System has three user modes - winter, summer and manual. In winter mode, the device uses internal temperature sensors and automatically adjusts the fan’s speed to keep the floor-to-ceiling temperature differential within 3°. The fan speed increases as the temperature at floor level rises during summer. And manual mode gives users full control over every aspect of operation. The three pushbutton controls allow you to switch between user modes while the LED lights are color-coded to identify the selected mode.
