Operator Notes

Stage 1 DX active; tracking discharge setpoint.

  • Air-temp panel pairs supply/return/mixed/outside so the operator can validate OA mixing on a packaged unit at a glance.
  • Supply-fan + VFD panel surfaces commanded speed, measured speed, amps, and fault state; VFD-fault hero chip is highlighted at the top.
  • DX cooling and heating stages are listed individually so staging order and runtime balance are visible — RTUs use staged DX, not modulating CHW.
  • Filter ΔP shows current loading vs alarm threshold so a filter-change reminder is obvious before it trips an alarm.
  • Alarm history surfaces both auto-reset events and OPEN trips that still require manual intervention.
