Operator Notes
Tracking HWS reset setpoint within 1.2°F; flame steady.
- 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.
