The Zero 6 Zone Ductless Multi-Zone Hyper Heat Pump System (Z4SOV-53HDMB-USHH) is a high-capacity, energy-efficient HVAC solution designed for large homes and commercial spaces requiring independent climate control across multiple rooms. With a total capacity of 53,000 BTU, this system includes six 9,000 BTU indoor units, making it ideal for whole-home comfort, multi-room layouts, and office environments.
This multi-zone system allows a single outdoor unit to support up to six indoor units, reducing installation complexity while optimizing outdoor space usage. Each indoor unit operates independently, enabling customized temperature settings for every room.
Built with next-generation R454B refrigerant, the system delivers high efficiency with significantly lower global warming potential (GWP), making it an environmentally responsible and future-ready HVAC solution.
Powered by advanced inverter technology, the system continuously adjusts output based on real-time demand. This ensures precise climate control, improved energy efficiency, and consistent indoor comfort. With efficiency ratings of ~16–18 SEER2 under higher load conditions (5+ zones), it maintains strong performance even at maximum capacity.
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 performance in harsh winter conditions.
Additional features such as outdoor unit self-cleaning and an easy installation port design enhance long-term reliability and simplify servicing. The Zero 6 Zone system is a powerful, flexible, and space-saving solution for year-round heating and cooling.
