Key Features & Benefits

Built-in Wi-Fi & Voice Control

The T Series includes built-in Wi-Fi, allowing you to control temperature, timers, and operating modes remotely through the AC Freedom App. It is also compatible with Google Home and Amazon Alexa for convenient voice control.

Strong Energy Efficiency

The 5.0kW model delivers up to a 4.5-star cooling efficiency rating in hot climates, helping reduce running costs while maintaining stable comfort. Inverter technology continuously adjusts compressor speed to improve efficiency and lower power usage.

Long Distance Airflow

The HSNRT50B can deliver airflow up to 12 metres, helping conditioned air reach further across larger rooms and reducing hot and cold spots. The indoor unit also includes 3D airflow, with blades that swing horizontally and vertically for more even temperature distribution.

Quiet Operation

Despite its larger capacity, the T Series is designed for quiet performance. Sleep Mode helps reduce operating noise overnight while still maintaining comfortable temperatures.

High-Density Air Filter

A high-density air filter helps capture dust, airborne particles, and impurities to create a cleaner indoor environment. The system also features a fresh air function and a self-cleaning cycle to reduce moisture build-up and help prevent mould, bacteria, and dust inside the unit.

Boost / Turbo Mode

Boost mode quickly cools or heats the room by running the system at maximum performance until the desired temperature is reached. This makes it ideal for very hot summer days or cold winter mornings.

Designed for Australian Conditions

The outdoor unit is designed to operate in harsh Australian climates, with an operating range from -15°C to 52°C outdoor temperature. DRED capability is also included for compatibility with energy demand response 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

The indoor unit measures approximately 316mm high, 997mm wide, and 227mm deep, making it suitable for medium to large rooms without taking up excessive wall space.

7-Year Residential Warranty

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