The Mitsubishi Heavy Industries FDUA140AVSXWVH is a high static reverse cycle ducted air conditioning system designed for large homes, offices, and commercial spaces that require strong airflow, long duct runs, and flexible zoning. As part of the FDUA series, it delivers discreet whole-home comfort while offering advanced features like High Power Mode, Silent Mode, Economy Mode, and built-in weekly timers. The system includes the FDUA140VH indoor unit, FDCA140VSX-W outdoor unit, and RC-EXZ3A wired wall controller. With 14.0kW cooling and 16.0kW heating capacity, this model is ideal for large open-plan homes, multi-room properties, offices, and commercial spaces around 65–100m² depending on insulation and layout. It can modulate from approximately 5.0kW to 14.5kW in cooling mode and from 4.0kW to 18.0kW in heating mode to maintain stable temperatures while reducing energy use.

Key Features & Benefits

High Static Pressure Performance

The system supports up to 150Pa–200Pa external static pressure, making it suitable for long duct runs, multiple outlets, and larger zoned ducted systems. Airflow ranges from approximately 600 litres per second on low fan speed up to 1,000 litres per second on powerful mode, helping maintain even air distribution throughout larger homes and commercial spaces.

3-Phase Power Supply

This model operates on 380–415V 3-phase power, making it suitable for larger homes and commercial buildings with 3-phase electrical supply. The 3-phase configuration helps distribute electrical load more evenly, which is ideal for larger-capacity ducted systems.

Energy Efficient Inverter Technology

The system uses inverter technology to automatically adjust output based on room conditions, helping provide more stable temperatures and lower running costs than fixed-speed systems. It delivers an EER of approximately 3.48 and a COP of approximately 3.82. Rated power input is approximately 4.02kW in cooling mode and 4.19kW in heating mode.

Strong Airflow Performance

The large indoor unit and high static design help deliver strong airflow across multiple rooms and long duct layouts. Supply air connection size is approximately 298mm x 1064mm, while the return air connection uses dual 400mm spigots for improved airflow distribution.

Quiet Operation

Indoor sound pressure levels range from approximately 38dBA on low fan speed up to 48dBA on powerful mode. Outdoor sound pressure is approximately 54dBA, helping maintain quieter operation for a system of this size. Silent Mode can also help reduce operating noise during overnight use.

RC-EXZ3A Wired Controller Included

The included RC-EXZ3A wired controller offers easy day-to-day control with weekly timer functions, sleep timer, temperature adjustment, fan speed selection, and operating mode changes. Wireless control options are also available.

Convenient Operating Modes

The FDUA series includes High Power Mode for rapid cooling and heating, Dry Mode to reduce humidity, Economy Mode to reduce power consumption, and Automatic Operation Mode for simplified day-to-day comfort.

R32 Refrigerant

The system uses modern R32 refrigerant for improved energy efficiency and lower environmental impact compared to older refrigerants. It includes approximately 4.0kg of refrigerant and comes pre-charged for pipe lengths up to 30 metres.

Long Pipe Run Capability

The system supports maximum pipe runs up to 100 metres, with a maximum height difference of 30 metres when the outdoor unit is above the indoor unit. This gives installers more flexibility for larger homes and complex layouts.

Compact Indoor Unit Design

The indoor unit measures approximately 398mm high, 1450mm wide, and 930mm deep, while the outdoor unit measures approximately 1300mm high, 970mm wide, and 370mm deep. Despite its large capacity, the system remains compact enough for many residential and commercial roof spaces.

Ideal Applications

• Large homes
• Open-plan living areas
• Offices
• Retail spaces
• Commercial buildings
• Homes with long duct runs
• Zoned ducted systems
