Operator Notes

Tracking CHWS setpoint within 0.4°F.

  • Compressor stage load and current draw are visible at a glance — confirms loading order.
  • Evap/cond pressure + saturation temp pair lets the operator infer approach and refrigerant health.
  • CHWS/CHWR context ties the chiller back to the plant-level setpoint tracking question.
  • Lead/lag role is shown read-only here; rotation is plant-policy, not commanded from this page.
  • Lockout history surfaces both auto-reset events and OPEN trips that still require manual intervention.
