The Rinnai High Static Ducted System DINLR10Z721/DONSR10Z72 is a reverse cycle ducted air conditioning system designed for medium to large homes, offices, and open-plan living areas that require strong airflow and flexible zoning. Its high static pressure capability makes it ideal for longer duct runs, multiple outlets, and larger homes requiring whole-home comfort from a single discreet system. It includes the DINLR10Z721 indoor unit, DONSR10Z72 outdoor unit, and a wired programmable controller with 12m cable. With 10.3kW cooling and 10.3kW heating capacity, this model is ideal for medium to large homes, offices, and spaces around 45–75m² depending on insulation and layout. The inverter system can modulate from approximately 4.0kW to 12.5kW in cooling mode and from 4.2kW to 12.5kW in heating mode, helping maintain more stable temperatures while reducing running costs.

Key Features & Benefits

High Static Pressure Performance

The system supports maximum external static pressure up to 200Pa, making it suitable for long duct runs, multiple outlets, and larger zoned ducted systems. Airflow reaches approximately 730 litres per second on high speed at 150Pa, helping maintain strong and 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 properties without requiring a 3-phase electrical upgrade. Maximum input current is approximately 21 amps with a recommended 25-amp to 32-amp circuit breaker.

Energy Efficient DC Inverter Technology

The system uses DC inverter technology to automatically adjust compressor speed based on room conditions, helping maintain more consistent temperatures and lower running costs compared to fixed-speed systems. It delivers an AEER of approximately 3.29 and an ACOP of approximately 3.63.

Strong Airflow Performance

Designed for larger homes and more demanding duct layouts, the system provides strong airflow across multiple rooms and longer duct runs. The high static design helps deliver even air distribution throughout larger living areas and zoned homes.

Quiet Operation

Indoor sound pressure levels range from approximately 40dBA on low speed to 47dBA on high speed. Outdoor sound pressure is approximately 61dBA, helping maintain comfortable day-to-day operation for a system of this size.

Wired Programmable Controller Included

The system includes a wired programmable controller with a 12-metre cable, allowing users to manage temperature, timers, fan speeds, and operating modes. Optional Wi-Fi control is also available for remote smartphone access.

Flexible Zoning Compatibility

Rinnai ducted systems support zoning, allowing different areas of the home to be heated or cooled independently. This helps improve comfort and reduce unnecessary energy use in unused rooms.

R410A Refrigerant

The system uses R410A refrigerant and comes pre-charged for pipe lengths up to 15 metres. It supports maximum pipe runs of up to 65 metres with a maximum vertical separation of 30 metres between indoor and outdoor units.

Wide Operating Range

The outdoor unit is designed to withstand Australian conditions, operating from -15°C to 50°C in cooling mode and from -15°C to 24°C in heating mode. This allows for reliable year-round comfort in a wide range of climates.

5 Year Manufacturer Warranty

Rinnai ducted systems include a 5-year manufacturer warranty on parts and labour when installed by a licensed technician in accordance with manufacturer guidelines.

Ideal Applications

• Medium to large homes
• Open-plan living areas
• Offices
• Multi-room homes
• Homes with long duct runs
• Zoned ducted systems
