Pioneer® Multi (4) Circuit Quantum Ultra Series 22.5 SEER2 Quad Zone Outdoor Section Inverter++ Energy-Star Air Conditioner Heat Pump 230V

For HVAC contractors and business owners who need a powerful, flexible, and efficient solution for multi-zone climate control, the Pioneer Multi (4) Circuit Quantum Ultra Series outdoor unit is engineered to deliver. This quad-zone inverter heat pump is designed to support up to four indoor units, offering the perfect balance of high performance and adaptability for residential or commercial installations covering 700 to 1,350 square feet.

What You Get with This Unit

Imagine providing your customers with a system that can precisely control temperatures in multiple rooms or zones, each with its own needs, all powered by one reliable outdoor unit. This Pioneer multi-zone system lets you configure indoor units in a variety of combinations—wall-mounted units ranging from 9,000 to 24,000 BTU—so you can tailor the setup exactly to the space and demand. Whether it’s a small office with several individual zones or a larger home needing distinct climate control in different rooms, this unit can handle it with ease.

Its 35,000 BTU cooling capacity and 36,000 BTU heating capacity deliver strong, consistent comfort. With an impressive 22.5 SEER2 cooling rating and 9.5 HSPF2 heating performance, this system keeps energy costs low while maintaining reliable operation year-round. The variable inverter compressor adjusts output dynamically based on real-time demand from all connected indoor units, ensuring smooth, efficient performance without wasting power.

Flexible and Efficient Operation

The outdoor unit’s smart self-regulating capacity means each indoor unit runs only as much as needed—between 30% and 100% of its capacity—while the outdoor unit modulates total output accordingly. This reduces wear and tear and prevents energy waste, making it a cost-effective choice for your customers. Plus, the system supports up to 133% of the outdoor unit’s rated capacity in combined indoor units, giving you room to customize without compromising performance.

With a quiet 65 dB(A) sound rating, this outdoor unit blends into any environment without disruption. The included R454B refrigerant is environmentally friendly, supporting green installations that meet modern standards.

Why This Unit Works for You

As a contractor or business owner, you want equipment that’s easy to install, flexible to configure, and reliable in performance. The Pioneer Multi (4) Circuit Quantum Ultra Series meets those needs with its robust build, versatile indoor unit compatibility, and advanced inverter technology. Offering multiple indoor unit combinations means you can serve a wider range of customers with one outdoor unit, reducing inventory complexity while maximizing sales opportunities.

When you bring this system to your customers, you’re delivering not just heating and cooling, but a tailored comfort experience that adapts to their lifestyle or business needs, all while helping them save on energy bills. It’s a smart investment for your business and a win for your customers.

    Notes
    • Different models of all available matching indoor units can be combined in any order to create a multi zone split system, up to a quantity of the number of available circuits.
    • Not all available circuits need to be utilized with an attached indoor unit. 66% or higher of the total capacity utilization is recommended.
    • Every indoor unit attached to a multi zone system will operate at a random, self-regulated capacity, based on the actual demand it measures from the zone it is serving (Between 30% to 100% of its rated capacity) or turn OFF as needed.
    • Outdoor unit will also self-regulate its total output capacity, based on the total demand it reads from all the simultaneously running indoor units at any given moment, up to its maximum rating capacity.
    • With multi split systems, the total demand from the outdoor unit, will seldomly exceed 75% of the total available capacity of the combined indoor unit group due to load fluctuations of each indoor unit.
    • Therefore, total attached indoor unit capacity can be selected up to 133% of the supporting outdoor unit's rated capacity.
    • Although very seldom, if the total demand from the combined group of indoor units' exceeds the rated capacity of the outdoor unit, the capacity of the each indoor unit will be annotated accordingly.
    • For high demand applications, max loading limits may need to be reduced up to 20% to avoid underperformance risks during some extreme conditions.

      Frequently Asked Questions about Pioneer® Multi (4) Circuit Quantum Ultra Series 22.5 SEER2 Quad Zone Outdoor Section Inverter++ Energy-Star Air Conditioner Heat Pump 230V

      Most Frequently Asked Questions

      The Pioneer Quantum Ultra Series 22.5 SEER2 Quad Zone Outdoor Inverter Heat Pump features ultra-high energy efficiency, independent control for up to four zones, inverter technology for precise temperature regulation and quiet operation, Energy Star certification, and reliable year-round heating and cooling for multiple rooms.

      The multi (4) circuit design allows a single outdoor unit to independently control and supply refrigerant to four separate indoor units, enabling customized cooling and heating for each zone or room.

      This unit has a high SEER2 energy efficiency rating, which means it uses less electricity to provide the same cooling output, resulting in lower energy bills and greater long-term savings.

      Other Questions

      The Pioneer Quantum Ultra Series is generally not compatible with existing central HVAC systems and requires dedicated electrical connections, refrigerant line installation, and adherence to manufacturer installation guidelines.

      For an Energy-Star certified outdoor heat pump, maintenance needs include regularly cleaning or replacing filters, inspecting and cleaning coils, checking refrigerant levels, clearing debris from around the unit, and scheduling annual professional servicing; warranty options typically include a limited parts warranty (often 5–10 years) and a separate compressor warranty, with coverage dependent on proper installation and registration.
