Features
• 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.
• Floor front panel access to the filter for ease of cleaning
• Mounts on floor or 5” above floor
• Multi-flow Vane for faster heating
• Multiple control options including: 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
• Nano Platinum Filter: This filter has a large capture area and incorporates nanometer-sized platinum-ceramic particles and is designed to reduce the
presence of certain nonliving particles, while deodorizing the circulating air.
• Perfect for difficult areas that may be smaller or don’t have usable space on the walls
• 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.
