Field Controller System Capacity Calculations

Important: When you upgrade from Release 5.x to Release 6.0 or later, or use the System Selection update as part of your upgrade process, the calculated object count may increase, which could potentially exceed system capacity. For more information on object counts and calculating system capacity, see System Capacity Indicator.

Output Controller Module Upgrades

  • Starting at Release 5.0, a new Tuning Reset Network Input was added. The tool only creates and connects this feature if you rerun System Selection. During the upgrade process, the interface to the PID is created, but is not connected.

  • Starting at Release 5.0, the Adaptive Tuning logic is disabled when the Output point associated with the Output Controller is overridden. The tool only creates and connects this feature if you rerun System Selection.

  • Starting at Release 5.1, the following feature updates were made to all Output Controllers:

    • General PID Process ID updates to key tuning parameters and timer settings per control loop type. The tool makes these changes during the upgrade process or when you rerun System Selection. See PID Pre-Processor.

    • Fast Switching logic occurs when the current heating command is zero and the zone temperature is greater than or equal to the effective cooling setpoint. This feature bypasses saturation timers when zones need to quickly transition from heating to cooling (for example, during major changes to space load conditions or setpoints). The tool only creates this logic if you rerun System Selection.

    • A new Lead Compensator block is automatically integrated into Output Controller modules for zone control loops on proportional water valves. This block acts as an anticipator and reduces the impact of the non-linearity of typical ball or globe valves. The tool only creates this logic if you rerun System Selection.

      Note: When Discharge Air Reset from zone is selected, the Lead Compensator is not used.

    • The PMAC Period is now 1/180th of the time constant rather than 1/30th with a minimum value of one second. This value change allows the Multi-Stage Controller (MSC) modules to reduce cycling of stages while maintaining setpoint in both the occupied or unoccupied modes. The tool makes this change if you rerun System Selection.

    • The Satisfied Timer Duration used to determine how long the unit stays on during unoccupied operation is now 30 seconds. The tool makes this change if you rerun System Selection; however, you may choose to manually update the Satisfied Timer Duration.
