Key Features & Benefits

Low Profile Indoor Unit

The indoor unit measures approximately 248mm high, 1100mm wide, and 720mm deep, making it suitable for tighter roof cavities and limited ceiling spaces. Despite its slim profile, it still delivers strong airflow across multiple rooms.

Single-Phase Power Supply

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

3D DC Inverter Technology

The system uses Rinnai’s 3D DC inverter technology to automatically vary compressor speed based on room conditions. This helps maintain more stable temperatures, faster response times, quieter operation, and lower running costs compared to fixed-speed systems.

Strong Airflow Performance

The system is designed to deliver strong airflow across multiple rooms and moderate duct runs. It uses insulated ductwork to rapidly distribute cooled or heated air while also helping filter the air as it circulates through the home.

Quiet Operation

The indoor fans and DC compressor are designed to operate quietly while maintaining strong airflow. Outdoor sound pressure is approximately 58dBA at 1 metre, helping minimise noise outside the home.

Flexible Zoning Options

The system supports whole-home or multi-zone ducted air conditioning, allowing different areas of the home to be heated or cooled independently for improved comfort and energy efficiency.

Wired Programmable Controller Included

A wired programmable controller with a 12-metre cable is included, making it easy to adjust temperature, fan speed, operating modes, and timers. Optional Wi-Fi control is also available for smartphone access.

R410A Refrigerant

The system uses R410A refrigerant and comes pre-charged for pipe lengths up to 15 metres. It supports maximum pipe runs up to 50 metres with a maximum height difference of 30 metres between indoor and outdoor units.

Wide Operating Range

The unit can operate in outdoor temperatures from -15°C to 50°C in cooling mode and from 0°C to 30°C in heating mode, making it suitable for Australian conditions year-round.

7 Year Warranty

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