What the GRMS Controls
SAUTER room controllers handle every in-room automation function from a single BACnet node per guest room.
SAUTER Room Controllers
SAUTER EY-RO series DDC modules provide room-level automation — HVAC setpoints, fan coil unit control, lighting logic, and occupancy-based modes from a single controller per room.
Lighting & Scene Management
Programmable lighting scenes (welcome, sleep, work, away) operated via in-room guest panels. Scene parameters are defined during commissioning and adjustable by the engineering team via the BMS.
HVAC & FCU Control
Guest-adjustable temperature control within operator-defined limits. Energy-saving setback activates automatically on unoccupied rooms via door/window contacts or PIR sensors.
DND / MUR Panel Integration
Do Not Disturb and Make Up Room status signals are connected to floor management and housekeeping consoles via BMS where compatible DND/MUR panel interfaces are included in the project scope.
Operations Dashboard
Real-time room occupancy status, HVAC fault alarms, energy setback states, and trend data visible from the engineering workstation running SAUTER CASE Suite visualisation software.
Third-Party Interface Readiness
Architecture supports connection to Property Management Systems, electronic access control, and VRF equipment. Compatibility and integration scope are confirmed project-specifically during design review.
SAUTER-Based Room Control Stack
SAUTER EY-RO series controllers installed at each guest room. Each unit handles FCU/HVAC, lighting relay outputs, sensor inputs, and panel communication over a local RS-485 or BACnet MS/TP bus.
Floor-level BACnet/IP gateways aggregate room controller data onto the hotel backbone network, passing all point data to the central GRMS server.
Engineering and housekeeping staff access room status, alarms, and energy trends through the SAUTER CASE Suite workstation — configurable to hotel floor plans and operational workflows.
Optional gateway modules support interfaces to PMS, electronic access systems, and other third-party platforms where compatibility has been confirmed as part of the project design.
Hospitality Project Types
In-Room & Operations Functions
From Site Survey to Handover
Assess existing mechanical systems, wiring infrastructure, riser space, and interface requirements. Produce a room controller schedule and initial BACnet point list.
Prepare riser diagram, system architecture drawing, SAUTER controller programming specification, and interface design documents for client and consultant review.
SAUTER room controllers configured and tested in-house. Panel schedules prepared for site-mounted floor aggregation hardware.
Controllers installed and commissioned room by room. Each room tested against the agreed point schedule before floor-level sign-off.
Engineering and housekeeping staff trained on SAUTER CASE Suite. As-built drawings, commissioning reports, and O&M documentation handed over.
Remote monitoring setup, warranty support, and optional service agreement covering periodic inspections and software updates.
Frequently Asked Questions
What is a Guest Room Management System (GRMS)?
A GRMS is a specialised building automation system for hotel guest rooms. It integrates HVAC, lighting, curtain control, and occupancy management via dedicated room controllers, enabling hotel operations to monitor room status, enforce energy setback on vacant rooms, and manage the guest environment from a central console.
Which GRMS platform does Intellicon use?
Intellicon integrates SAUTER room controllers (EY-RO series) and the SAUTER CASE Suite visualisation platform for GRMS projects. SAUTER controllers communicate over BACnet/IP, enabling integration with the hotel's wider building management system.
Can a GRMS connect to the hotel's Property Management System (PMS)?
Integration with a PMS is possible where a supported interface or gateway is included in the project design. Compatibility is subject to project-specific design review, equipment selection, and operator approval. Intellicon assesses PMS interface requirements during the site survey and design phase.
What energy savings can a hotel expect from a GRMS?
A GRMS enables HVAC and lighting setback on unoccupied rooms, reducing energy load. Actual savings depend on hotel occupancy patterns, the mechanical system design, selected setback parameters, and site conditions. No energy savings figure is guaranteed — estimates are prepared project-specifically.
Is a GRMS suitable for existing hotels or only new builds?
Intellicon designs GRMS solutions for both new-build and retrofit hotel projects. Retrofit feasibility depends on existing wiring infrastructure, mechanical equipment, riser space, and ceiling access. A site survey is required to confirm scope and cost before any retrofit proposal is issued.
