Don’t just set your ceiling fan to its mid-speed setting and hope to be comfortable; you’ll waste energy running the fan motor when you don’t really need it. This fan control has a thermostat, which tells the fan when to run only when it’s needed. The control module is installed inside the junction box and the sensor module is placed on the ceiling adjacent to the fan. Use the remote control (included) to turn the fan on and off and adjust temperature settings. Save energy by recirculating the warm air that naturally rises to the top of a room, reducing the need to additional heat.
