The Zero 4 Zone Ductless Multi-Zone Hyper Heat Pump System (Z4SOV-27HDMB-USHH) is a high-performance and energy-efficient HVAC solution designed to deliver independent climate control across four rooms. With a total capacity of 36,000 BTU, this system includes four 9,000 BTU indoor units, making it ideal for bedrooms, living areas, offices, and multi-room residential setups.
This multi-zone system connects multiple indoor units to a single outdoor unit, reducing installation complexity while maximizing space efficiency. Each indoor unit operates independently, allowing customized temperature control for every room.
Built with next-generation R454B refrigerant, the system provides improved energy efficiency with a significantly lower global warming potential (GWP), making it a future-ready and environmentally responsible solution.
