The Zero 2 Zone Ductless Multi-Zone Hyper Heat Pump System (Z4SOV-18HDMB-USHH) is an advanced and energy-efficient HVAC solution designed for precise climate control across two rooms. With a total capacity of 18,000 BTU, this system includes two 9,000 BTU indoor units, making it ideal for bedrooms, offices, and small living areas.
This multi-zone system allows a single outdoor unit to support multiple indoor units, reducing installation complexity and saving outdoor space. Each indoor unit operates independently, allowing personalized temperature control for each zone.
Built with next-generation R454B refrigerant, the system delivers high efficiency with a significantly lower global warming potential (GWP), making it an environmentally responsible choice.
Equipped with inverter technology, the system continuously adjusts performance based on real-time demand, ensuring consistent comfort, quiet operation, and reduced energy consumption. With efficiency ratings of up to ~20 SEER2 for 2–3 zone systems, it offers excellent energy savings.
Designed for extreme climates, the Hyper Heat system provides reliable heating even at temperatures as low as –30°C. Features like intelligent auto defrost and a chassis heater belt ensure stable operation in harsh winter conditions.
Additional features such as outdoor unit self-cleaning and an easy installation port enhance long-term reliability and simplify maintenance. This makes the Zero 2 Zone system a future-ready solution for year-round comfort.
