Haier Multi-Zone Solutions
Introduction
Haier's Multi-Zone Solutions offer single-zone features, benefits, and performance suitable for multi-zone applications. By matching one outdoor unit with a variety of indoor units, contractors gain unprecedented application flexibility.
Proper sizing and installation are critical for optimal performance. Split system air conditioners and heat pumps must be matched with appropriate coil components to meet ENERGY STAR® Criteria. Consult your contractor or visit www.energystar.gov for details.
Series Overview & Key Features
Haier offers two main series for multi-zone applications:
FlexFit Series
Features include:
- R454B Refrigerant: A lower Global Warming Potential (GWP), eco-friendly option that meets updated refrigerant guidelines while maintaining high efficiency.
- Over-the-Air Updates: A high-speed communication wire between the outdoor and indoor unit allows outdoor unit over-the-air (OTA) updates via the SmartHQ™ Home app.
- DC Inverter Technology: Enhances energy efficiency, cuts costs, and improves reliability, making it ideal for energy-conscious homeowners.
- Blue Fin: Hydrophilic aluminum fin provides corrosion protection and ensures smooth water flow for long-lasting performance.
- Auto Start: Automatically restarts the system after a power outage for seamless operation.
- Ten-Year Limited Warranty: Double the standard five-year limited warranty by registering the unit, providing homeowners with additional peace of mind.
Arctic Series
Features include:
- R454B Refrigerant: A lower Global Warming Potential (GWP), eco-friendly option that meets updated refrigerant guidelines while maintaining high efficiency.
- Over-the-Air Updates: A high-speed communication wire between the outdoor and indoor unit allows outdoor unit over-the-air (OTA) updates via the SmartHQ™ Home app.
- DC Inverter Technology: Enhances energy efficiency, cuts costs, and improves reliability, making it ideal for energy-conscious homeowners.
- Blue Fin: Hydrophilic aluminum fin provides corrosion protection and ensures smooth water flow for long-lasting performance.
- Auto Start: Automatically restarts the system after a power outage for seamless operation.
- Basepan Heater: Prevents ice buildup and condensate water accumulation in the outdoor unit, ensuring smooth operation.
- -22°F Heating: Reliable low ambient heating down to -22°F ensures comfort and efficiency even in extreme conditions.
Both series operate within specified temperature ranges, with cooling below 23°F requiring a wind baffle.
