Operator Notes

Locked out: low water cutoff trip not auto-reset; manual intervention required.

  • Firing rate plus flame status answers the first heating-side question instantly: is this boiler producing heat right now?
  • Stack temp + O₂/CO give a fast read on combustion health and condensing efficiency.
  • HWS/HWR/Δ-T pair ties the boiler 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.
