The Daikin FDYA125AV19 / RZAS125C2V1 is a premium reverse cycle ducted system designed for medium to large homes, open-plan living spaces, and multi-room applications. As part of Daikin’s Premium Inverter range, it offers stronger seasonal efficiency, quieter performance, and greater installation flexibility than the standard FDYAN series while remaining concealed within the ceiling space.
With 12.5kW cooling and 15.0kW heating capacity, this model is ideal for larger family homes, 4–5 bedroom properties, and open-plan areas around 70–100m² depending on insulation and layout. The inverter compressor can modulate output from 5.0kW up to 14.0kW in cooling mode and from 5.1kW up to 16.0kW in heating mode, helping maintain more stable indoor temperatures and lower running costs.
Key Features & Benefits
Premium Inverter Technology
Daikin’s Premium Inverter range uses a redesigned cross-pass heat exchanger, DC fan motor, and enhanced outdoor coil design to deliver stronger energy performance, smoother temperature control, and quieter operation than standard ducted systems.
Improved Energy Efficiency
The system delivers an EER of 3.62 and COP of 3.95, with residential piping capability up to 75 metres. This higher efficiency can help reduce ongoing running costs compared to conventional or fixed-speed systems.
Compact Indoor Unit Design
The indoor unit has a low-profile height of approximately 360mm, making it suitable for homes with limited roof space. Indoor dimensions are approximately 360mm high, 1520mm wide, and 935mm deep.
Strong Airflow Performance
The unit provides rated airflow of approximately 755 litres per second, helping deliver even conditioned air across multiple rooms and open-plan spaces. Indoor sound levels are approximately 44.8dBA.
Long Pipe Run Capability
The Premium series supports refrigerant pipe lengths up to 75 metres, giving installers greater flexibility for multi-storey homes and more complex ducted layouts.
Night Quiet Mode
Daikin’s Night Quiet Mode automatically reduces outdoor operating noise during sleeping hours and resumes normal operation in the morning, helping minimise disturbance to occupants and neighbours.
R22 Retrofit Capability
This model supports R22 retrofit applications, allowing existing pipework to often be reused when replacing older systems. This can help reduce installation time and overall project cost.
R32 Refrigerant
The system uses modern R32 refrigerant for improved efficiency and lower environmental impact compared to older refrigerants. Daikin uses R32 across its Premium Ducted range from 7.1kW to 20.0kW.
Single-Phase Power Supply
This model operates on standard 220–240V single-phase power, making it suitable for most residential homes without requiring 3-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 ducted systems are backed by a 5-year manufacturer warranty for residential applications when professionally installed and maintained.
