The MITSUBISHI ELECTRIC PEAM125GAAYKIT2 is a high static reverse cycle ducted air conditioning system designed for larger homes, offices, and renovation projects where strong airflow and 3-phase power are required. Its two-piece indoor unit design makes installation easier in tight roof spaces and existing homes, while still delivering powerful whole-home heating and cooling. The system includes the PEA-M125HAA indoor unit, PUZ-ZM125YKA2-A outdoor unit, and PAR-40MAA backlit wall controller. With 12.5kW cooling and 14.0kW heating capacity, this model is ideal for larger homes, open-plan living areas, offices, and spaces around 55–90m² depending on insulation and layout. It can modulate from approximately 5.5kW to 14.0kW in cooling mode and from 5.0kW to 16.0kW in heating mode for more stable temperatures and improved efficiency.

Key Features & Benefits

Two-Piece Indoor Unit Construction

One of the standout features of the PEA-M-HAA series is its two-piece indoor design. The fan section can be separated from the heat exchanger section, making installation much easier in existing homes with narrow roof access, tight ceiling spaces, or limited clearance between roof trusses.

High Static Pressure Performance

The system supports adjustable external static pressure settings up to 150Pa, making it suitable for long duct runs, multiple outlets, and larger zoned homes. Multiple fan speed settings allow installers to fine-tune airflow for different layouts and comfort requirements.

3-Phase Power Supply

This model operates on 380–415V 3-phase power, making it suitable for larger residential homes and commercial properties with 3-phase electrical supply. The 3-phase configuration helps spread electrical load more evenly across the property, making it ideal for larger-capacity systems.

Energy Efficient Inverter Technology

The system uses Mitsubishi Electric inverter technology to automatically adjust compressor speed based on room conditions, helping maintain more consistent temperatures and lower running costs. It delivers an EER of approximately 3.55, COP of approximately 4.28, AEER of approximately 3.45, and ACOP of approximately 4.15.

Strong Airflow Performance

Designed for larger homes and more demanding duct layouts, the system delivers airflow from approximately 800 to 1000 litres per second depending on fan speed. The high static pressure design ensures even airflow across long duct runs and multiple zones.

Quiet Operation

Indoor sound pressure levels range from approximately 42dBA to 45dBA depending on fan speed, while outdoor sound levels are approximately 54–56dBA. This helps maintain quieter day-to-day performance for a system of this size.

Flexible Zoning and Wi-Fi Compatibility

Optional zoning allows the system to control up to 4 or 8 zones, helping reduce energy use by conditioning only occupied areas. An optional Wi-Fi adaptor also allows remote control via smartphone, tablet, Alexa, or Google Assistant.

R32 Refrigerant

The system uses modern R32 refrigerant for improved efficiency and lower environmental impact compared to older refrigerants.

Compact Indoor Unit Design

The indoor unit measures approximately 380mm high, 1405mm wide, and 900mm deep, while the outdoor unit measures approximately 1338mm high, 1050mm wide, and 330mm deep. Despite its larger capacity, the system remains compact enough for many residential roof spaces.

Long Pipe Run Capability

The system supports maximum pipe runs of up to 75 metres with a maximum height difference of 30 metres between indoor and outdoor units, providing installers with more flexibility for larger homes and complex layouts.

Ideal Applications

• Large homes
• Open-plan living areas
•  Existing homes with limited roof access
• Home renovations
• Offices
• Zoned ducted systems
• Homes with long duct runs
