Features
• 3D i-see Sensor (Built-in): The advanced sensor scans each room to produce a complete thermal profile that includes heat signatures based upon size,
temperature and movement, then adjusts temperature and airflow based on user preference, and saves energy according to room occupancy.
• Dual Barrier Coating: The patented Dual Barrier Coating reduces the collection of contaminants like dust, fibers, smoke, and oil on the inner surface of
the heat pump, resulting in optimal airflow and easier maintenance.
• Dual Barrier Fusion: The patented Dual Barrier Fusion reduces the collection of contaminants like dust, fibers, smoke, and oil on the vanes of the indoor
unit, keeping it clean all year long. Dual Barrier Fusion’s shielding power is fused directly into the material of the horizontal and vertical vanes during
manufacturing to maintain effectiveness and longevity of the components, and to promote vane cleanliness and reduce odors.
• Dual Vane: Dual-Vane feature allows for airflow direction to be set independently using two vanes, which can then deliver airflow across wide areas of a
room, levels of a zone, or to two people in different locations at the same time.
• Econo Cool: Econo Cool temporarily and automatically adjusts the airflow based on heat exchanger temperature. The set temperature is increased
slightly, which saves energy, while maintaining comfort.
• Multiple control options including: Back-lit screen hand-held Remote Controller (provided with unit), comfort app, third-party interfaces and both wired
and wireless controllers
• Multiple fan speed options: Low, Medium, High, Powerful, Auto
• Powerful Mode: Temporarily drops or raises the set point and fan speed in order to quickly bring the room to the desired temperature.
