ao_pct: 100
di_pct: 50
do_pct: 100
hli_pct: 80

basis: |
  Hospitality + casino. Casino MVAC + chiller plant require comprehensive
  trending for energy-management reporting and gaming-regulator IAQ
  compliance.

  AI 100% — all temperatures, pressures, flows, energy meters trended for
  energy reports + alarm forensics.

  AO 100% — all valve / damper / VFD-speed commands trended for sequence
  verification.

  DI 50% — slightly elevated above standard 40% to capture casino-floor
  status changes (ionizer, exhaust trip) for incident review. Toilet
  exhaust + general exhaust DI are not trended (high noise, low value).

  DO 100% — start/stop commands trended for runtime and on-off cycling
  analytics.

  HLI 80% — chiller / boiler / VFD integration sub-points: 80% trended
  (energy + status), 20% diagnostic-only sub-points not trended.
