# Instance: BMS Controller Panel — Kingsford BMS

**WBS leaves served:** 2.3.1, 2.3.2, 2.3.3, 2.3.4, 2.3.5, 3.4.1, 3.4.2, 3.4.3, 3.4.4
**Module ref:** `_playbook/modules/bms/controller-panel.md`
**Project:** Kingsford Hotel Bacolod BMS

## Project-specific parameter values

- `panel_count`: **18** (per A4)
- `total_controllers`: **30** (per A4)
- `total_physical_io`: **523** (AI 126 + AO 29 + DI 348 + DO 20 = 523 per cumulative A1; subtract AI/AO from A1 actual = 126+29 = 155 plus DI 348 + DO 20 = 503 — verify)
- `total_network_drops`: **27** (per A1 Network type rows)
- `total_hli_subpoints`: 166 (per A1, drives programming hours but not physical I/O modules)
- `enclosure_size_distribution`: ~10 small + 6 medium + 2 large (refine per A4 panel I/O density)
- `redundant_psu_required`: yes for plant-room critical panels (PNL-CH-PLANT-GND, PNL-CHWP-L2, PNL-AHU-L2, PNL-DOAS-L2, PNL-BL-LZ, PNL-EE-MAIN — 6 panels)

## Open assumptions for this instance

- Controller sizing rule (1 DDC per 40 physical I/O + network gateway): refine per Q-008 wiring topology
- I/O module size = 16-channel typical; refine per BMS vendor's product line (per Q-013)
- 25% I/O spare capacity included
- Brand: per Q-013 (Honeywell/Siemens/Schneider/Johnson Controls/Tridium)
- Wall-mount IP54 enclosures all panels (indoor)

## Cross-references

- **Working docs:** A4 (panel schedule — primary), A1 (I/O count per panel), A5 (network drops), A7 (panel power)
- **Assumptions:** A-007, A-CHW-001, A-CHW-002 (drive panel scope at chiller plant)
- **Clarifications:** Q-008 (mech layout — refines wiring topology), Q-013 (brand)
