Zero 4 Zone (4 Head) Ductless Multi-Zone Heat Pump System – 36,000 BTU (4 × 9,000 BTU)

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.

Powered by advanced inverter technology, the system continuously adjusts output based on real-time demand. This ensures precise temperature control, enhanced comfort, and reduced energy consumption. With efficiency ratings of ~17–19 SEER2 for 4–5 zone systems, it delivers strong performance and energy savings.

Engineered for extreme climates, the Hyper Heat system provides reliable heating even at outdoor temperatures as low as –30°C. Intelligent auto defrost and a chassis heater belt ensure stable and efficient operation in harsh winter conditions.

Additional features such as outdoor unit self-cleaning and an easy installation port improve long-term performance and simplify servicing. The Zero 4 Zone system is a powerful, flexible, and space-saving solution for year-round comfort.
