Guest Room Management Systems (GRMS) are the backbone of modern hospitality lighting control. By integrating lighting with HVAC, shading, and building systems, GRMS delivers both superior guest experience and significant energy savings — typically 30-45% across the property.
GRMS CORE FUNCTIONS
Occupancy Detection
Card-key and sensor-based presence detection for energy management
Climate Integration
Coordinated lighting and HVAC for unified comfort control
DND/MUR Integration
Do Not Disturb and Make Up Room status with housekeeping alerts
Scene Management
Pre-programmed scenes accessible from bedside panels and tablets
CONTROL LEVELS BY ROOM TYPE
Basic
$Economy/Standard rooms
Simple scene control with master switch and card-key energy management
Enhanced
$$Superior/Deluxe rooms
Multi-zone control with scene presets and HVAC coordination
Premium
$$$Suites/Villas
Full automation with tablet control and personalization
ENERGY SAVINGS
| Scenario | Savings | Strategy |
|---|---|---|
| Room Occupied | — | Scene presets encourage efficient use |
| Card Out (<2 hrs) | 30-40% | Setback mode, lights off, HVAC reduced |
| Extended Absence | 50-60% | Deep setback, minimal systems |
| Check-out | 70-80% | Full power-down except maintenance |
PUBLIC SPACE CONTROLS
| Space | Control Strategy | Protocol |
|---|---|---|
| Lobby | Time-scheduled scenes with daylight compensation | DALI-2 + BMS |
| Corridors | Motion-triggered with ambient background | DALI-2 |
| Ballrooms | Preset scenes with partition awareness | DALI-2 + DMX |
| F&B Outlets | Day-part scheduling with manual override | DALI-2 |
| Pool/Spa | Time + occupancy with chromotherapy | DALI-2 + RGB |
| Back of House | Occupancy sensing, high efficiency | Basic switching |
