Honeywell Deploys Cabin Automation on Royal Caribbean Icon-Class Ships

On October 30, 2026, Honeywell Building Automation announced that its connected cabin automation system has covered more than 8,400 staterooms across three in-service Icon-class ships of Royal Caribbean. Each stateroom uses a programmable logic controller (PLC) as the local hardware hub, linking HVAC adjustment, motorized curtains, lighting and digital door locks, and connects to Royal Caribbean's native app for passengers to adjust lighting scenes, temperature and window shades. The system can dynamically adjust HVAC output based on real-time occupancy status and outdoor environment, and automatically reduces cooling load when a balcony door or motorized window is opened. The system is currently in use on three in-service Icon-class ships.
