Features

Blue Fin Coating
  • An anti-corrosion treatment applied to the aluminum fins of the heat exchanger of the outdoor unit to protect against corrosion caused
  • by salt, sulfur, and other airborne contaminants, especially in coastal and industrial areas.
H2i sumo™ Hyper-Heating INVERTER
  • 100% heating capacity at outdoor temperatures -10° F with guaranteed operation down to -22° F.
Hot-start technology
  • The fan only blows air when the heat exchanger has warmed, preventing blasts of cold air at start-up.

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 h
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.
Quiet operation
  • Outdoor units are as quiet as a typical conversation, and most indoor units are whisper quiet.
Slim Design
  • Slim wall-mounted indoor units provide zone comfort control
Smart Dry +
  • The Smart Dry+ mode intelligently provides precise humidity control with minimal over-cooling of the space.
Triple Action Filtration
  • Standard Microparticle and Electrostatic Enzyme Filters, along with an optional Carbon-based Deodorizing Filter. It effectively removes non-living particulate matter like dust and smoke, utilizes nanotechnology to absorb and neutralize odors, and employs
Wi-Fi
  • Enabled units pair with the Comfort app for complete control over temperature, fan speeds, modes, schedules, and more
