Wired guestroom control · Four engineering essentials
Unlike wireless retrofit — wired fixes topology inconstruction phase, stability and maintainability inoperations.
Central relays · local scenes
Multi-circuit lighting, curtains, card power driven by RCU relays/dimmers; Welcome, sleep, night paths preset on host, no cloud dependency.
panels · reusable key maps
Bedside, entry, desk use standard 86 boxes; key/scene table in factory config; chain stores clone silk and logic.
Luxury new build · full fit-out first choice
Join at LV riser and conduit stage; one-time wiring long-term use; suited to international luxury and reliability-first projects.
Construction schedule comparison
Switch by property type — for tender "technology route" and closure plan; compare withwireless solution.
| Comparison | Wired guestroom control system | Wireless RCU | RS485 bus |
|---|---|---|---|
| Schedule | Full fit-out low-voltage 15–25 days/floor | Interleaved with fit-out, 5–10 days/floor | 12–18 days/floor |
| Cabling | Star low-voltage to each panel | Gateway power + wireless panels | Single bus + module addresses |
| Best for | Full-fit luxury, stability priority | Tight-schedule new build / boutique chain | Chain standard room batch replication |
| Risk | Chase cost and schedule | Wall shielding needs survey | Address conflicts and terminal matching |
| Comparison | Wired guestroom control system | Wireless RCU | Hybrid (wired backbone + wireless endpoints) |
|---|---|---|---|
| Schedule | Chasing 5–8 days/floor | 0.5–1 day/room; 3–5 days/floor | 4–6 days/floor |
| Cabling | Full-room low-voltage rewire | Gateway near LV box; wireless card power/panels | Riser bus + wireless bedside/bath |
| Best for | Full renovation, floor closure OK | Legacy hotels, economy upgrades | Standard room wired + suite wireless extension |
| Risk | Revenue loss from closure | Metal partitions; battery O&M | Two protocol doc sets to align |
| Comparison | Wired guestroom control system | Panel swap only (keep existing wiring) | Modular chassis add-on |
|---|---|---|---|
| Schedule | 5–7 days/floor (chasing required) | 1–2 days/room | 3–4 days/floor (add circuits) |
| Cabling | Add star low-voltage to new points | Reuse existing low-voltage | Swap modules in box; minor LV adjustment |
| Best for | Mock-up first, partial floor closure | Legacy system OK, UI upgrade only | Need more circuits for HVAC/curtains |
| Risk | Conflict with existing conduits | Features limited by legacy host | Enclosure space and cooling |

Wired RCU vs wireless RCU
Select by property — wired emphasizesstability and circuit expansion, wirelessretrofit schedule; same 6-point BOM types, different networking and modules.
| Comparison | Wired guestroom control system | Wireless RCU guestroom control |
|---|---|---|
| Wiring form | Star low-voltage to RCU host | Gateway + wireless panels/modules, minimal cabling |
| Construction window | New build / full fit-out with structure | Existing retrofit, short schedule, minimal wall opening |
| Scene response | ★★★★★ local relays, low latency | ★★★★☆ gateway and battery maintenance |
| Circuit expansion | Relay/dimmer modules as needed | Limited by wireless points and gateway capacity |
| Troubleshooting | Terminal table + wire numbers, electrician-friendly | Gateway logs + module pairing |
| Typical project | Luxury new build, full-fit business hotel | Legacy retrofit, B&B economy |
