The system automatically adjusts the duct static pressure setpoint based on the damper position of the zone that needs the most cooling. It increments or decrements the duct static pressure setpoint so that the damper position of this zone is maintained between 85% and 95% open. If the damper position rises above 95%, it increases the duct static pressure setpoint by 0.1 in. (2.54 mm) Water Column (W.C.). If the damper position drops below 85%, it decrements the duct static pressure setpoint by 0.1 in. W.C. The system waits 10 minutes between setpoint adjustments. No adjustment occurs if the damper position is between 85% and 95% open. A maximum duct static pressure setpoint adjustment parameter limits the range of adjustment (Max Duct Static SP Adjust). The user can disable the duct static pressure reset strategy.
