The Daikin FDYAN125AV1 / RZA125C2V1 is a high-capacity reverse cycle ducted system designed for medium to large homes, open-plan living spaces, and multi-room applications. With inverter technology, a compact indoor profile, and quiet operation, it delivers 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, multi-storey properties, and open-plan areas 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
Advanced Inverter Technology
Daikin’s inverter technology continuously adjusts compressor speed to maintain a more stable indoor temperature while reducing power consumption and operating noise compared to conventional fixed-speed systems. The system uses a hermetically sealed compressor, DC fan motor, and enhanced outdoor coil design for efficient and reliable performance.
Compact Indoor Unit Design
The indoor unit has a low-profile height of approximately 360mm, making it ideal for tighter roof spaces in modern homes. Indoor dimensions are approximately 360mm high, 1520mm wide, and 935mm deep. The outdoor unit measures around 990mm high, 940mm wide, and 320mm deep.
Night Quiet Mode
Daikin’s Night Quiet Mode reduces outdoor noise levels during sleeping hours and automatically resumes normal operation in the morning, helping minimise disturbance to occupants and neighbours.
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.
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 up to 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.
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.
R32 Refrigerant
The system uses modern R32 refrigerant for improved efficiency and lower environmental impact compared to older refrigerants.
Single-Phase Power Supply
This model operates on standard 220–240V single-phase power, making it suitable for most residential installations without requiring three-phase power.
Wired Controller Included
The system is commonly supplied with Daikin’s BRC1E63 wired wall controller, providing simple scheduling, temperature control, and system management.
5-Year Manufacturer Warranty
Daikin backs this model with a 5-year manufacturer warranty for residential applications when professionally installed and maintained.
