SYSE.2:5.3 - Occupied building heat-pump control

For HeatPumpPlant-HP1, ControllerConfig-C2, the next heating season, and ArchitectureDecision-AD1, the three compatible input accounts use the same subject, configuration, use, horizon, evidence window, and receiving decision:

  • the SYSE.16 use-context account states the BuildingHeatingSystem-BH1 proper-part claim, energy and information transfers, plant-room access permission, and unsupported latency, override, insulation, and clearance assumptions;
  • the SYSE.17 affected-system account supplies the qualified AcousticResult-AR4, SafetyResult-SR7, ThermalResult-TR5, and their authority boundaries, including the unmeasured neighbour-noise and cabinet- clearance branches; and
  • the SYSE.8 provider-arrangement account supplies only the supported provider claims and design constraints: actual provider System MaintenanceTeam-MT4, the current access permission, expected diagnostic Work, the communications bearer, and the missing commitment and authority result for remote monitoring.

The three accounts change the linked proposal as follows:

use claim: occupied rooms remain within the selected thermal range while qualified neighbour-noise and maintenance-access constraints hold
system-concept claim: ControllerConfig-C2 includes a cycle-rate limit, a low-noise branch, a measurable cabinet-location alternative, and a latency-tested override-safe branch
main uncertainty: night acoustic measurement and plant-room clearance are unavailable; remote-monitoring authority and commitment are unresolved
architecture question: which controller, sensor, cabinet, communications, and operating structures support those qualified claims
reopen condition: a specialist result, measurement, provider result, or operating observation defeats one of the linked claims

The remote-monitoring branch remains conditional because the provider-authority and commitment result is unavailable. Realization and WorkPlan descriptions may include cabinet relocation, access preparation, and test Work. Keep those realization and WorkPlan descriptions distinct from the System concept. If no feasible architecture supports the linked claims, revise this proposal. Reopen SYSE.1 only if the failure changes the project focus itself.
