The MITSUBISHI ELECTRIC PEAM125HAAYKIT2 is a high static reverse cycle ducted air conditioning system designed for larger homes, offices, and commercial spaces that require powerful airflow and flexible installation. Featuring Mitsubishi Electric’s two-piece indoor unit construction, this system is easier to transport and install in restricted roof spaces while still delivering reliable whole-home comfort. The system includes the PEA-M125HAA indoor unit, PUZ-M125YKA outdoor unit, and PAR-40MAA backlit wall controller. With 12.5kW cooling and 14.0kW heating capacity, this model is ideal for large 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 4.1kW to 15.5kW in heating mode for more stable temperatures and reduced running costs.

Key Features & Benefits

Two-Piece Indoor Unit Construction

The fan section can be separated from the heat exchanger section, making installation much easier in homes with narrow roof access, tight ceiling spaces, or limited clearance between roof trusses. This makes the PEA-M series especially suitable for renovations and retrofit applications.

High Static Pressure Performance

The system supports adjustable external static pressure settings of 50Pa, 100Pa, and 150Pa, making it suitable for long duct runs, multiple outlets, and larger zoned homes. Four fan speed settings allow airflow to be tailored for different layouts and comfort requirements.

3-Phase Power Supply

This model operates on 400–415V 3-phase power, making it suitable for larger residential and commercial properties with 3-phase electrical supply. The 3-phase configuration helps distribute electrical load more evenly and is 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 than fixed-speed systems.

Strong Airflow Performance

Designed for larger homes and demanding duct layouts, the system delivers strong and even airflow throughout the property. The high static pressure design ensures consistent performance across long duct runs and multiple zones.

Quiet Operation

Indoor sound pressure levels range from approximately 34dBA on low speed to 41dBA on high speed, helping 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.

PAR-40MAA Controller Included

The included PAR-40MAA backlit wired wall controller provides simple operation with timer functions, airflow settings, temperature adjustment, and easy-to-read display controls.

Ideal Applications

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