The Zero 18,000 BTU 2-Zone Ductless Hyper Heat Pump System (Z4SOV-18HDMB-USHH) is a premium heating and cooling solution designed to provide independent climate control for two separate rooms. This configuration includes one 9,000 BTU indoor unit and one 12,000 BTU indoor unit (9K + 12K), making it ideal for applications where rooms require different heating and cooling capacities, such as bedrooms, living rooms, home offices, or larger open spaces.
Powered by a single outdoor unit, this multi-zone system delivers quiet, energy-efficient comfort while allowing each indoor unit to operate independently. Individual zone control lets you customize the temperature in each room, improving comfort while reducing unnecessary energy consumption.
Built with next-generation R454B refrigerant, advanced inverter technology, and Hyper Heat performance, the system provides outstanding energy efficiency and dependable heating in outdoor temperatures as low as –30°C, making it an excellent choice for Canadian climates.
