Hotel Room Control System with Integrated KNX RCU
KNX RCU for Smart Hotel Rooms
KN/RC1805A · KN/RC1803A · KN/RC1802B
Build a hotel room control system around one integrated KNX RCU for lighting, fan coil, curtain and dry-contact control. This RCU series provides the room-level control core for smart hotel rooms and other multi-room projects, with project-specific configuration and OEM support. A complete system also requires compatible panels, sensors, lighting drivers, HVAC interfaces and commissioning according to the approved project design.

The product manual lists KN/RC1805A, KN/RC1803A and KN/RC1802B. Functions and channel allocation depend on the selected model and project configuration. Confirm the final wiring schedule, loads, ETS application and firmware before ordering.
These are reference specifications from the Room Control Unit Product Manual V1.0. Electrical loads, terminal assignments, interface behavior and configuration should be checked against the selected model and approved project design.
Hotel Room Control Functions in One KNX RCU
- Lighting: relay switching plus a selected 0–10 V or DALI lighting option. The DALI application describes up to 64 ECGs and 16 groups in the reference configuration.
- Fan coil: three fan-speed outputs with heating and cooling control; the ETS application describes 2-pipe and 4-pipe systems, not 3-pipe control.
- Curtains: up to four curtain channels using relay pairs R11/R12 through R17/R18 for up/down operation.
- Room inputs and indicators: 21 passive dry-contact inputs and 21 powered outputs can be assigned to the approved panel and room-status design.
- KNX commissioning: ETS parameters cover switching, fan coil, curtains, dry contacts, 0–10 V and DALI. Confirm the current application database and communication objects for the delivered firmware.
OEM Options and Hotel Room Control System Planning
For distributors, integrators and teams planning smart hotel rooms, OEM requests can include logo, packaging, enclosure, firmware, ETS and interface configuration. Feasibility and the final scope are assessed for each model and order; send us your project brief for review.
- Share the room schedule: quantity, market, supply voltage, lighting loads, fan-coil type, curtain motors and panel or DND/MUR requirements.
- Select the RCU model and either the 0–10 V or DALI lighting configuration; review I/O assignments and integration protocols.
- Confirm the OEM scope, technical files and a mock-up room test before volume rollout.
- Request a quotation for pricing, sample availability, MOQ, lead time and warranty based on the confirmed specification.
Sample availability, technical documents, MOQ, lead time and warranty are confirmed by model and project requirements; sending a request does not reserve stock or fix commercial terms.
Hotel Room Control System FAQs
Which KNX RCU models are available for a hotel room control system?
The product manual identifies KN/RC1805A, KN/RC1803A and KN/RC1802B. We confirm the appropriate model and final channel allocation against your room schedule.
Can I use DALI and 0–10 V at the same time?
No. The reference hardware specifies four 0–10 V channels or one DALI channel as mutually exclusive options. State your lighting architecture when requesting a quote.
Does the RCU control fan coils and curtains?
The documented ETS functions include three-speed fan-coil control for 2-pipe or 4-pipe systems and up to four curtain channels. Motor, valve, load and wiring compatibility must be checked for the project.
Can you customize the RCU for our brand?
OEM options may include logo, packaging, enclosure, firmware, ETS and interface configuration. The available scope is assessed for the selected model, quantity and project requirements.
What are the sample price, MOQ and production lead time?
We provide these details by quotation after confirming the model, quantity and customization scope. Share your project brief to receive a relevant offer.
Smart Hotel Room Control Project Reference
A 420-room smart hotel automation proposal shows the project approach: one integrated controller per room, lighting and curtain control, fan-coil operation, dry-contact room-status inputs and a mock-up room before rollout. The case documents a project design rather than a promise that every interface works without engineering validation.
