Its slimline indoor unit is designed to fit neatly into tighter roof spaces while still providing whole-home heating and cooling through discreet ceiling vents. It includes a wired programmable controller with a 12-metre cable for easy day-to-day operation. With 7.1kW cooling and 8.2kW heating capacity, this model is best suited to homes with 2–3 bedrooms, open-plan living areas, and spaces around 30–55m² depending on insulation and layout. The inverter system can modulate from approximately 2.8kW to 8.4kW in cooling mode and from 3.0kW to 9.0kW in heating mode, helping maintain stable temperatures while reducing energy use.

Key Features & Benefits

Slimline Indoor Unit Design

The indoor unit measures approximately 1100mm wide, 720mm deep, and 248mm high, making it ideal for homes with limited ceiling space or narrow roof cavities. Its low-profile design helps simplify installation in both new homes and renovations.

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 current draw is approximately 16 amps with a recommended 20–25 amp circuit breaker.

Energy Efficient Inverter Technology

The Rinnai DRCi system uses advanced DC inverter technology and 3D DC synchronisation to deliver faster warm-up and cool-down times while maintaining strong efficiency. It achieves an AEER of approximately 3.37 and an ACOP of approximately 3.4.

Strong Airflow Performance

The indoor fan delivers airflow of approximately 490 litres per second at 100Pa external static pressure, helping provide even air distribution across multiple rooms and longer duct runs. Maximum external static pressure is approximately 160Pa.

Quiet Operation

Indoor sound pressure levels are approximately 45dBA on high fan speed, 41dBA on medium, and 38dBA on low. The outdoor unit operates at approximately 58dBA, helping maintain quieter operation for a whole-home ducted system.

Wired Controller Included

The included wired programmable controller provides simple access to temperature adjustment, timer functions, fan speed settings, mode selection, child lock, and LCD display controls.

Optional Wi-Fi Compatibility

Optional Wi-Fi control is available through the NetHome Plus app, allowing users to remotely control temperatures, operating modes, and timers from a smartphone or tablet.
