For systems with DDC of individual zone reporting to the central control panel static pressure setpoint shall be reset based on the zone requiring the most pressure, such as the setpoint is reset lower until one zone damper is nearly wide open. Controls shall provide the following:
- Monitor zone damper positions or other indicator of need for static pressure.
- Automatically detect those zones that are capable of excessively driving the reset logic and generate an alarm to the system operator.
- Readily allow operator removal of zone(s) from the reset algorithm. [ASHRAE 90.1:18.104.22.168.3]
