The Daikin FDYA200AV1 / RZAS200DY1 is a premium reverse cycle ducted system designed for very large homes, multi-storey properties, open-plan living areas, and commercial spaces with 3-phase power available. As part of Daikin’s Premium Inverter range, it delivers stronger seasonal efficiency, quieter operation, and greater installation flexibility than the standard FDYQN series while remaining concealed within the ceiling space. With 20.0kW cooling and 22.4kW heating capacity, this model is ideal for large homes, 5+ bedroom properties, offices, retail spaces, and areas around 100–150m² depending on insulation and layout. The inverter compressor can modulate output from approximately 10.0kW up to 22.4kW in cooling mode and from 11.2kW up to 25.0kW in heating mode, helping maintain stable indoor temperatures and lower running costs.

Key Features & Benefits

Premium Inverter Technology

Daikin’s Premium Inverter range uses advanced refrigerant control, a high-efficiency DC fan motor, and a hermetically sealed scroll compressor to deliver smoother temperature control, quieter operation, and stronger seasonal efficiency than standard ducted systems.

R32 Refrigerant

Unlike older large-capacity ducted models that use R410A, the FDYA200AV1 / RZAS200DY1 uses modern R32 refrigerant for improved efficiency and lower environmental impact. Daikin introduced the new 18kW and 20kW Premium series specifically to provide better seasonal performance and meet current Australian standards.

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. It helps spread electrical demand more evenly across circuits compared to large single-phase systems.

Strong Airflow Performance

The unit provides rated airflow of approximately 1400 litres per second, with maximum airflow reaching up to 1600 litres per second. This helps deliver even conditioned air across multiple rooms and large open-plan spaces. Indoor sound levels are approximately 46dBA on high fan speed.

Compact Indoor and Outdoor Design

Despite its large capacity, the indoor unit remains relatively compact for easier installation in modern homes. The indoor unit measures approximately 470mm high, 1400mm wide, and 997mm deep, while the outdoor unit measures approximately 1657mm high, 930mm wide, and 765mm deep.

Long Pipe Run Capability

The Premium series supports refrigerant pipe lengths up to 50 metres, giving installers greater flexibility for larger homes, multi-storey properties, 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.

Improved Energy Efficiency

The system delivers an EER of approximately 3.19 and COP of 3.27, helping reduce energy use while maintaining strong heating and cooling performance. Efficiency improvements come from the DC fan motor, cross-pass heat exchanger, and enhanced outdoor coil design.

Optional Refrigerant Leak Detection

Daikin offers an optional refrigerant leak detector sensor for installations where refrigerant concentration limits must comply with AS/NZS60335:2:40 requirements. When activated, the system can automatically stop the compressor and switch to fan-only mode for added safety.

Wired Controller Compatibility

The system is commonly paired with Daikin’s BRC1E63 wired wall controller, with optional zoning controllers also available for larger homes and commercial installations. Some suppliers note the controller may be sold separately depending on the package.

5-Year Manufacturer Warranty

Daikin ducted systems are backed by a 5-year manufacturer warranty for residential applications when professionally installed and maintained.

• 5+ bedroom homes
• Multi-storey properties
• Open-plan living areas
