The Daikin FDYQN200LCV1 / RZQ200MY1 is a high-capacity reverse cycle ducted system designed for large homes, multi-storey properties, 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 19.5kW cooling and 22.4kW heating capacity, this model is ideal for larger homes, 5-bedroom properties, offices, retail spaces, and areas around 100–150m² depending on insulation and layout. The inverter compressor can modulate output from 10.1kW up to 19.5kW in cooling mode and from 11.2kW up to 22.4kW 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 larger homes and commercial properties with 3-phase electrical supply. It can help reduce electrical load across circuits compared to equivalent large-capacity 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 scroll compressor for reliable performance.
Compact Indoor Unit Design
The indoor unit measures approximately 470mm high, 1400mm wide, and 997mm deep, while the outdoor unit measures around 1430mm high, 940mm wide, and 320mm deep. Despite its large capacity, the system is designed to fit within many roof spaces and maintain installation flexibility.
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 speed.
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 3.19 and COP of 3.27, helping reduce running costs while maintaining strong heating and cooling performance. Efficiency improvements are achieved through the use of a DC fan motor, cross-pass heat exchanger, and enhanced outdoor coil design.
Long Pipe Run Capability
The system supports refrigerant pipe lengths up to 50 metres, making it suitable for larger homes and more complex ducted installations. Some premium variants can support even longer pipe runs.
Wide Operating Range
The system can operate in cooling mode from -5°C to 43°C outdoor temperature and in heating mode from -20°C to 16°C outdoor temperature, making it suitable for year-round Australian conditions.
R410A Refrigerant
This model uses R410A refrigerant, which is common across Daikin’s larger-capacity ducted systems from 18kW upwards.
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.
15 Fan Speed Settings
The system includes 15 fan speed settings, allowing installers to fine-tune airflow to suit the ductwork configuration and deliver more balanced airflow throughout the home.
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
- Large homes
- Multi-storey properties
- Open-plan living areas
- 5-bedroom homes
- Offices
- Retail and commercial spaces with 3-phase power
