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 noise reduction function helping minimise disturbance outside the home. This makes it ideal for bedrooms, nurseries, and study spaces.

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 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 water 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.

3D Airflow with Multiple Patterns

The Seiya Plus system provides efficient airflow with multiple louvre positions and airflow patterns to help distribute conditioned air more evenly throughout the room.

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.

Strong Energy Efficiency

Toshiba’s inverter technology helps the system deliver efficient heating and cooling while keeping power consumption lower than conventional fixed-speed systems.

Wide Operating Range

The system can operate in cooling mode from -10°C to 46°C outdoor temperature and heating mode from -15°C to 24°C, making it suitable for a wide range of Australian climates.

Compact Design

Despite its higher output, the indoor unit is designed to fit neatly into bedrooms, studies, apartments, and living spaces without dominating the room.

R32 Refrigerant

The Seiya Plus uses modern R32 refrigerant for improved energy efficiency and a lower environmental impact compared to older refrigerants.
