Operator Notes

Supply temp tracking setpoint within 0.6°F.

  • Air-temp panel pairs supply/return/mixed/outside so the operator can sanity-check coil work and OA mixing in one glance.
  • Supply-fan + VFD panel surfaces commanded speed, measured speed, amps, and fault state — three different fault signatures are distinguishable.
  • Cooling and heating coil panels expose valve position and leaving-air temp; activeness flags surface as hero chips for at-a-glance state.
  • 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.
