Key Features & Benefits

Built-in Wi-Fi Control

The PB Series includes built-in Wi-Fi, allowing you to control temperature, timers, and operating modes remotely through the NetHome Plus App on your smartphone or tablet. This makes it easy to adjust your air conditioner before you arrive home.

Strong Energy Efficiency

The HSNRP80B delivers up to a 3.5-star cooling efficiency rating in hot climates. Inverter technology continuously adjusts compressor speed to maintain stable temperatures while reducing running costs and energy use. Heating efficiency is rated up to 3 stars in hot climates.

Quiet Operation

Despite its larger capacity, the PB Series is designed for low-noise comfort. Indoor sound pressure levels range from approximately 29.5dBA on minimum fan speed to 57.6dBA on turbo mode, making it suitable for living rooms, bedrooms, and larger family areas.

3D Airflow

Horizontal and vertical swing functions help distribute conditioned air more evenly around the room, reducing hot and cold spots and improving comfort. The indoor unit provides airflow rates up to approximately 382L/s in turbo mode.

Turbo Function

Turbo Mode allows the system to quickly cool in summer or warm in winter by temporarily running at maximum performance until the desired temperature is reached. This makes it ideal for very hot summer days or cold winter mornings.

Dehumidifying Mode

A built-in dehumidifying function helps manage humidity levels during humid weather, improving comfort and indoor air quality. This can make larger rooms feel cooler and more comfortable during warmer months.

Timer & Sleep Functions

The PB Series includes timer functionality, allowing you to set the unit to turn on or off automatically at specific times. Sleep Mode adjusts temperature gradually overnight for more comfortable sleeping conditions.

Designed for Australian Conditions

The outdoor unit is built for Australian climates and includes GoldGuard™ corrosion protection for improved durability in coastal and harsh environments. The unit can operate in cooling mode up to 50°C outdoor temperature and heating mode down to -15°C. It is also DRED enabled for compatibility with demand response energy programs.

Eco-Friendly R32 Refrigerant

The system uses modern R32 refrigerant, which improves energy efficiency and has a lower environmental impact than older refrigerants.

Compact Design for Its Capacity

Despite its larger output, the indoor unit remains relatively compact at approximately 337mm high, 1082mm wide, and 234mm deep. The outdoor unit is designed to fit comfortably in most residential installations without taking up excessive space.

7-Year Residential Warranty

Rinnai backs the PB Series with a 7-year residential warranty for added peace of mind.
