Description

Pioneer® Multi (2) Circuit Quantum Ultra Series 24 SEER2 Dual Zone Outdoor Section Inverter++ Energy-Star Air Conditioner Heat Pump 230V

If you’re a contractor or HVAC business owner looking for a compact, highly efficient dual-zone outdoor unit that delivers reliable comfort and flexibility, the Pioneer Multi (2) Circuit Quantum Ultra Series is built to meet your needs. Designed for spaces between 300 and 750 square feet, this Energy-Star rated heat pump combines advanced inverter technology with smart multi-zone capability to give your customers precise climate control with minimal energy use.

What You Can Expect from This Unit

Imagine installing a system that lets your customers control two separate zones independently, each with its own indoor unit, while you manage everything through one streamlined outdoor unit. This Pioneer dual-zone outdoor section offers an 18,000 BTU cooling capacity and 20,000 BTU heating capacity, making it perfect for small to medium-sized spaces like apartments, offices, or retail environments.

With a remarkable 24 SEER2 rating and an EER2 of 13.0, this unit is engineered for energy efficiency that saves your customers money month after month. The inverter-driven compressor adjusts output dynamically based on real-time demand, providing just the right amount of cooling or heating without wasting energy.

Flexible Indoor Unit Compatibility

This outdoor unit supports a variety of wall-mounted indoor units, including 9,000, 12,000, and 18,000 BTU models, which can be mixed and matched to best fit your customers’ needs. Common dual-zone combinations include setups like 9k + 9k, 9k + 12k, 12k + 12k, or 18k + 9k, giving you the flexibility to tailor each installation precisely.

Intelligent Load Management

One of the standout features of this system is its self-regulating capacity. Each indoor unit modulates between 30% and 100% of its rated capacity based on the zone’s demand, or turns off when not needed. The outdoor unit reads the combined demand from all indoor units and adjusts its output accordingly, rarely exceeding 75% of the total indoor capacity due to natural load fluctuations. This smart operation helps reduce energy consumption and wear on the system.

You can safely size the total indoor unit capacity up to 133% of the outdoor unit’s rating, giving you flexibility to design systems that meet varying load requirements without compromising performance. For high-demand environments, reducing max loading by up to 20% may be necessary to maintain optimal operation during extreme conditions.

Practical Features and Installation

This Pioneer outdoor unit runs quietly at 58 dB(A), blending easily into residential or commercial settings without disruption. It uses eco-friendly R454B refrigerant and requires a 20A double-pole circuit breaker for safe operation. Its compact footprint (36-1/2" x 15" x 27-1/2") and moderate weight (93 lbs net) make it manageable for your installation teams.

Why This Unit Works for Your Business

As an HVAC professional, you want equipment that offers reliable performance, flexibility, and energy efficiency—without complicating your inventory or installation processes. The Pioneer Multi (2) Circuit Quantum Ultra Series dual-zone outdoor unit does just that. It supports multiple indoor unit configurations, adapts intelligently to changing demands, and delivers high-efficiency operation that your customers will appreciate on their utility bills.

By choosing this unit, you’re providing a proven, versatile solution that meets the needs of today’s multi-zone applications, helping you grow your business with satisfied customers who enjoy dependable, cost-effective comfort year-round.

    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.
