The Rinnai DINLR10Z721 / DONSR10Z72 is a high static reverse cycle ducted air conditioning system designed for medium to large homes, open-plan living areas, and multi-room properties. Its slimline indoor unit and strong airflow performance make it ideal for whole-home heating and cooling where longer duct runs and multiple outlets are required. The system includes a wired programmable controller with a 12-metre cable for easy day-to-day operation. With 10.3kW cooling and 10.3kW heating capacity, this model is ideal for homes and living areas around 45–75m² depending on insulation and layout. The DC inverter compressor automatically adjusts output to maintain stable temperatures while reducing running costs.

Key Features & Benefits

High Static Pressure Performance

The system is designed for longer duct runs, multiple outlets, and larger zoned installations. It supports maximum external static pressure up to 200Pa and delivers airflow up to approximately 730 litres per second at 150Pa, helping maintain even air distribution throughout the property.

Single-Phase Power Supply

This model operates on standard 220–240V single-phase power, making it suitable for most residential homes without requiring a 3-phase electrical upgrade.

Energy Efficient DC Inverter Technology

The Rinnai DRCi range uses a 3D DC inverter system to automatically adjust compressor speed based on room conditions. This helps deliver more stable temperatures, quieter operation, and lower running costs than fixed-speed systems. Rinnai states the range can achieve up to a 3.4-star cooling efficiency rating in hot climates.

Strong Airflow Performance

The indoor unit is designed to deliver strong airflow across multiple rooms and open-plan areas. Its high airflow output and larger supply air opening help provide even temperature distribution across the home.

Quiet Operation

Indoor sound pressure levels are approximately 47dBA on high fan speed, 43dBA on medium, and 40dBA on low speed. The outdoor unit sound pressure level is approximately 58dBA.

Compact Slimline Indoor Unit

The indoor unit measures approximately 1200mm wide, 625mm deep, and 380mm high, making it suitable for many residential roof spaces.

Optional Wi-Fi Compatibility

The system supports optional Wi-Fi control through the NetHome Plus app, allowing users to remotely manage temperatures, operating modes, and timers from a compatible smartphone.

Wide Operating Range

The system is designed to handle Australian climate conditions, operating in outdoor temperatures from approximately -15°C to 46°C in cooling mode and from -15°C to 24°C in heating mode.

R32 Refrigerant

The system uses modern R32 refrigerant, which provides improved energy efficiency and lower environmental impact compared to older refrigerants.

7 Year Manufacturer Warranty

Rinnai ducted systems are backed by a 7-year limited manufacturer warranty when installed by a licensed technician in accordance with manufacturer guidelines.
