Toshiba’s twin-rotary inverter compressor helps maintain stable temperatures while reducing energy consumption and operating noise.
Key Features & Benefits
Quiet Operation
The Seiya Plus range is designed for low-noise comfort, with Toshiba’s Quiet mode reducing indoor sound levels and a dedicated outdoor silent mode helping minimise disturbance outside the home. This makes it ideal for bedrooms, living areas, and family rooms where quieter operation is important.
Advanced Inverter Technology
Toshiba’s inverter technology continuously adjusts compressor speed to maintain a more stable room temperature while reducing power usage and improving efficiency. The twin-rotary compressor also helps lower vibration and operating noise.
IAQ Air Filtration
The integrated IAQ filter helps remove dust, odours, smoke particles, mould, fungi, and airborne pollutants to improve indoor air quality and create a cleaner living environment.
Magic Coil Self-Cleaning Function
Toshiba’s acrylic resin-coated Magic Coil helps prevent dust and moisture from sticking to the indoor coil. After operation, the fan continues to run briefly to help keep the coil clean and dry, reducing mould and bacteria build-up over time.
Enhanced 3D Airflow
The 9.0kW Seiya Plus includes Toshiba’s enhanced 3D airflow system with multiple airflow patterns, helping distribute conditioned air more evenly across larger open-plan areas and family rooms. Models from 6.0kW upwards include broader airflow coverage for larger spaces.
Comfort Sleep Mode & Eco Mode
Comfort Sleep Mode automatically adjusts the temperature overnight for a more comfortable sleeping environment, while Eco Mode helps reduce unnecessary energy consumption. Frost Protection Mode, Boost Mode, and Weekly Timer functions are also included.
Optional Wi-Fi Control
The Seiya Plus range supports optional Wi-Fi connectivity, allowing you to control the system remotely through a compatible smartphone app when paired with Toshiba’s optional Wi-Fi adapter.
Strong Energy Efficiency
The 9.0kW Seiya Plus model delivers around 3-star cooling efficiency and 3-star heating efficiency in average climate zones, helping reduce running costs while maintaining strong performance in larger spaces.
Wide Operating Range
The system is designed for Australian conditions and can continue operating in cooling mode from -10°C to 46°C and heating mode from -15°C to 24°C outdoor temperature.
Compact Design for Its Capacity
Despite its larger output, the indoor unit maintains a relatively slim profile at approximately 1200mm wide, 350mm high, and 280mm deep, while the outdoor unit measures around 900mm wide, 320mm high, and 890mm deep.
R32 Refrigerant
The Seiya Plus uses modern R32 refrigerant for improved energy efficiency and a lower environmental impact compared to older refrigerants.
7-Year Manufacturer Warranty
Toshiba backs the Seiya Plus range with a 7-year manufacturer warranty for added peace of mind.
