INDOOR UNIT FEATURES
• 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.
• 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.
• Modern, sleek design
• 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
OUTDOOR UNIT 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.
• High-performance grooved piping : High-performance grooved piping for increased heat exchange efficiency
• Hot-Start Technology: Hot-Start Technology ensures the fan only activates once the heat exchanger is warm, preventing cold air blasts during start-up.
• INVERTER-driven compressor: An inverter-driven compressor generates the precise capacity needed to maintain a temperature set point.
• Joint Lap DC Motor: Innovative Joint Lap DC Motor leads to high efficiency and reliability
• Outdoor unit directed power: The outdoor unit powers the indoor unit, and should a power outage occur, the system is automatically restarted when
power returns
• Pulse Amplitude Modulation technology: Pulse Amplitude Modulation technology enhances energy efficiency by adjusting the power supply to optimize
compressor performance, ensuring precise capacity control and reduced energy consumption.
• Quiet operation: Quiet operation units are as quiet as a typical conversation, and most indoor units are whisper quiet.
• Single-zone: One outdoor unit connects to one indoor unit to control the comfort in a single space.
