i-SEE Sensor™ Technology
The 3D i-SEE Sensor scans rooms to detect hot and cold spots, then directs airflow exactly where needed. It can even detect human presence and adjust operation for energy savings when rooms are empty.
Dual Barrier Coating
Exclusive coating on indoor units prevents dust and dirt buildup on internal components. This maintains efficiency, improves air quality, and reduces maintenance needs over the system's lifetime.
kumo cloud® Control
Control your ductless system from anywhere with kumo cloud. Adjust temperatures, set schedules, monitor energy use, and receive maintenance alerts all from your smartphone or tablet.
Hot-Start Technology
Prevents cold air blowing during heating startup. The system pre-warms the heat exchanger before fan operation, ensuring only warm air enters your space - especially important with Hyper Heat systems.
