Output Controller module upgrades - Metasys - LIT-12011832 - General System Information - Metasys System - 12.0

• Starting at Release 5.0, an Adaptive Tuning Reset Network Input was added. This feature is created and connected only if you re-run 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. This feature is created and connected only if you re-run System Selection.
• Starting a Release 5.1, the following feature updates were made to all Output Controllers:
  • General PID Process ID updates have been made to key tuning parameters and timer settings per control loop type. These changes are updated from either an upgrade or system selection.
  • Fast Switching logic that bypasses saturation timers when zones need to quickly transition from heating to cooling (for example, load changes in the space or setpoint changes). This logic is only created from system selection.
  • A new Lead Compensator block is automatically integrated into output controller modules for zone control loops on water valves. This block acts as like an anticipator and reduces the impact of the non-linearity of typical ball or globe valves. This is only created from system selection.
  • Updates to the default timer settings on Multi-Stage Controller (MSC) modules that reduce cycling of stages while maintaining setpoint in both the occupied or unoccupied modes. These timer settings are updated during system selection or manual updates of the unoccupied duration timer.
• Starting at Release 5.1, updates to Output Controller Modules that contain PID and PID preprocessor blocks are made even when the module has been user modified:
  • Output Controllers utilized with Proportional Outputs are fully upgraded with the latest logic and all the necessary internal connections.
  • Output Controllers utilized with Staged/MSC Outputs are upgraded with the latest primitives but the connections between the blocks are not made. Instead, the PID primitive uses the default tuning parameters.
• Starting at Release 5.1, four exponentially weighted moving average (EWMA) parameters are added automatically exposed during system selection to all the Output Controllers doing Zone Control (VAV Boxes, Fan Coils, Unit Vents, and Heat Pumps).
