The Daikin FDYAN125AV1 / RZA125C2Y1 is a powerful reverse cycle ducted system designed for medium to large homes, open-plan living areas, and commercial spaces with 3-phase power available. With inverter technology, a compact indoor profile, and quiet operation, it provides discreet year-round comfort while remaining hidden within the ceiling space.
With 12.5kW cooling and 15.0kW heating capacity, this model is ideal for larger homes, 4–5 bedroom properties, offices, and spaces around 70–100m² depending on insulation and layout. The inverter compressor can modulate output from 4.0kW up to 14.0kW in cooling mode and from 4.1kW up to 16.0kW in heating mode, helping improve efficiency and maintain stable indoor temperatures.
Key Features & Benefits
3-Phase Power Supply
This model operates on 380–415V 3-phase power, making it suitable for homes and commercial properties with 3-phase electrical supply. It can help reduce electrical load across circuits compared to larger single-phase systems.
Advanced Inverter Technology
Daikin’s inverter technology continuously adjusts compressor speed to maintain a more stable indoor temperature while reducing energy use and operating noise compared to conventional fixed-speed systems. The system uses a hermetically sealed swing compressor and high-efficiency DC fan motor for reliable performance.
Compact Indoor Unit Design
The indoor unit has a low-profile height of approximately 360mm, making it ideal for tight roof spaces in modern homes. Indoor dimensions are approximately 360mm high, 1520mm wide, and 935mm deep, while the outdoor unit measures around 990mm high, 940mm wide, and 320mm deep.
Strong Airflow Performance
The unit provides rated airflow of approximately 755 litres per second, with maximum airflow up to 840 litres per second, helping deliver even conditioned air across multiple rooms and open-plan spaces. Indoor sound levels are approximately 44.2dBA in cooling mode and 45.5dBA in heating mode.
Night Quiet Mode
Daikin’s Night Quiet Mode reduces outdoor operating noise during sleeping hours and automatically resumes normal operation in the morning, helping minimise disturbance to occupants and neighbours.
Improved Energy Efficiency
The system delivers an EER of 3.17 and COP of 3.75, helping reduce running costs while maintaining strong heating and cooling performance. Residential TCSPF ratings reach approximately 4.26 in hot climates.
Long Pipe Run Capability
The system supports refrigerant pipe lengths up to 50 metres, making it suitable for multi-room homes and more complex ducted installations.
Wide Operating Range
The system can operate in cooling mode from -5°C to 46°C outdoor temperature and in heating mode from -15°C to 16°C outdoor temperature, making it suitable for year-round Australian conditions.
R32 Refrigerant
The system uses modern R32 refrigerant for improved efficiency and lower environmental impact compared to older refrigerants.
R22 Retrofit Capability
This model supports R22 retrofit applications, allowing existing pipework to often be reused when replacing older systems, helping reduce installation time and costs.
Wired Controller Compatibility
The system is commonly paired with Daikin’s BRC1E63 wired wall controller, providing simple scheduling, temperature control, and system management.
5-Year Manufacturer Warranty
Daikin ducted systems are backed by a 5-year manufacturer warranty for residential applications when professionally installed and maintained.
Ideal Applications
- 4–5 bedroom homes
- Open-plan living areas
- Medium to large homes
