5.6.6 INTERMITTENT FAN
Intermittent Fan function allows the fan to run periodically when the heating/cooling equipment is off. Many times this functionality is used to improve the performance of air cleaning or special filtration systems.
When the Intermittent Fan function is active, the fan output will be activated for the currently selected Intermittent Fan On Time, and then operate using the selected Intermittent Fan Off and On times until a heating or cooling operation is activated again.
After the heating or cooling operation is complete, the intermittent fan operation will resume with the beginning of a new Intermittent Fan On Time on the ¼ hour.
•On Time (default Off): options: Off, 5 to 20 minutes (in 5 minute increments)
•Off Time: options: 5 to 90 minutes (in 5 minute increments)
NOTE: This intermittent fan operation can also improve the performance of air cleaning or special filtration systems that locate the cleaning or filtration media at the return air side of the fan.
