As part of Daikin’s Premium Inverter range, it delivers stronger energy efficiency, quieter operation, and greater installation flexibility than the standard FDYQN series while remaining concealed within the ceiling space. The system offers 24.0kW cooling and 26.8kW heating capacity, making it ideal for large homes, offices, showrooms, retail spaces, and areas around 120–180m² depending on insulation and layout.
Key Features & Benefits
Premium Inverter Technology
Daikin’s Premium Inverter range uses advanced refrigerant control, a high-efficiency DC fan motor, redesigned cross-pass heat exchanger, and hermetically sealed scroll compressor to deliver smoother temperature control, quieter performance, and stronger seasonal efficiency than standard ducted systems.
Strong Heating and Cooling Capacity
This system delivers 24.0kW cooling and 26.8kW heating, with a capacity range of 15.0kW to 24.0kW in cooling mode and 16.8kW to 26.8kW in heating mode. This wide operating range helps the system adapt to varying seasonal demands while maintaining stable indoor temperatures.
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 distribute electrical demand more evenly across circuits compared to large-capacity single-phase systems.
Improved Energy Efficiency
The system delivers an EER of 3.21 and COP of 3.29, helping reduce running costs while maintaining strong heating and cooling performance. Residential TCSPF ratings reach approximately 3.97 in hot climates.
Strong Airflow Performance
The unit provides rated airflow of approximately 1400 litres per second, with maximum airflow 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 in both cooling and heating modes.
Compact Indoor and Outdoor Design
Despite its large capacity, the indoor unit remains relatively compact for easier installation in larger properties. Indoor dimensions are approximately 470mm high, 1400mm wide, and 997mm deep, while the outdoor unit measures around 1657mm high, 930mm wide, and 765mm deep.
Long Pipe Run Capability
The Premium series supports refrigerant pipe lengths up to 150 metres, giving installers far greater flexibility for multi-storey homes, commercial sites, 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.
R410A Refrigerant
This model uses R410A refrigerant, which is standard across Daikin’s 24kW Premium Ducted range.
R22 Retrofit Capability
This system supports R22 retrofit applications, allowing existing pipework to often be reused when replacing older systems. This can help reduce installation time and project costs.
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.
