  ESP = External Static Pressure (inches of water)



Maximum allowable duct static



 Continuous airflow is the CFM being circulated with manual fan operation without any additional function occurring.



 Will occur automatically for first 5 minutes of Part Load Cooling Operation.



 Will occur automatically after five minutes of Part Load Cooling Operation.



  Will occur automatically with control signal input.
