The Zero 5 Zone Ductless Multi-Zone Hyper Heat Pump System is a high-capacity, energy-efficient HVAC solution designed for large homes, multi-level properties, offices, and light commercial spaces requiring independent climate control across multiple rooms. With a nominal outdoor capacity of 53,000 BTU, this configuration includes five 12,000 BTU wall-mounted indoor units for balanced comfort across five separate zones.
A single outdoor unit supports all five indoor units, helping reduce outdoor equipment requirements while simplifying the overall system layout. Each indoor unit operates independently, allowing users to select a different temperature, operating mode, and fan setting for every room.
Built with advanced inverter technology, the system continuously adjusts compressor output according to real-time heating and cooling demand. This supports more stable indoor temperatures, quieter operation, improved efficiency, and reduced energy consumption compared with conventional fixed-speed systems.
Hyper Heat technology provides reliable cold-climate heating performance in outdoor temperatures as low as –30°C, making the system suitable for Canadian winters. During warmer months, it delivers efficient cooling across all connected zones for dependable year-round comfort.
The system uses next-generation R454B refrigerant, which has a lower global warming potential than traditional refrigerants. Intelligent auto defrost, a chassis heater belt, outdoor-unit self-cleaning, and service-friendly access help maintain dependable performance in demanding climate conditions.
Capacity note: The outdoor unit has a nominal capacity of 53,000 BTU, while the five connected 12,000 BTU indoor units provide a combined connected capacity of 60,000 BTU. Installation must follow the manufacturer’s approved indoor-unit combinations and connection requirements.
