The Tjernlund Automatic Duct Booster Fan - 6" is controlled by a pressure response control (PRC). This PRC will sense the positive pressure being created in the duct and will turn the fan on when the system fan is running. Then, the fan will continue to run after the system shuts off in order to distribute the warm or cool air to the room(s).
Make sure to use the Tjernlund Automatic Duct Booster Fan - 6" in branch ducts and not in the main supply duct from your forced air system. This will help give the fan proper function. When installing the fan, it is best to position it near the end of the duct to provide the most efficient performance.
