The Daikin FDYA85AV19 / RZAS85C2V1 is a premium reverse cycle ducted system designed for medium-sized homes, townhouses, and open-plan living areas. As part of Daikin’s Premium Inverter range, it delivers higher efficiency, quieter operation, and greater installation flexibility than the standard FDYAN series, while remaining concealed within the ceiling space.
With 8.5kW cooling and 10.0kW heating capacity, this model is ideal for 3–4 bedroom homes, larger family rooms, and spaces around 38–70m² depending on insulation and layout. The inverter compressor can modulate output from 3.2kW up to 10.0kW in cooling mode and from 3.5kW up to 11.2kW in heating mode, helping maintain more stable temperatures and reduce running costs.
Key Features & Benefits
Premium Inverter Technology
Daikin’s Premium Inverter range uses a redesigned cross-pass heat exchanger, DC fan motor, and hermetically sealed swing compressor to deliver stronger seasonal efficiency and quieter performance than standard ducted models.
Improved Energy Efficiency
The system delivers an EER of approximately 3.36 and COP of 3.57, with residential TCSPF ratings up to 4.29 in hot climates. This helps reduce energy use and ongoing running costs compared to older or fixed-speed systems.
Compact Indoor Unit Design
The indoor unit has a low-profile height of approximately 300mm, making it ideal for modern homes with limited roof space. Indoor dimensions are approximately 300mm high, 1210mm wide, and 900mm deep, while the outdoor unit measures around 990mm high, 940mm wide, and 320mm deep.
Strong Airflow Performance
The unit provides rated airflow of approximately 580 litres per second, with maximum airflow up to 600 litres per second. This helps deliver even conditioned air across multiple rooms and open-plan spaces. Indoor sound levels are approximately 42.0dBA in cooling mode and 42.4dBA in heating mode.
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.
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.
