    Overview

    The Rinnai TX Series Split System Air Conditioner combines powerful performance with smart technology to deliver year-round comfort in Australian homes. Designed to efficiently cool in summer and warm in winter, it utilises advanced inverter technology to maintain consistent indoor temperatures while helping to minimise energy consumption. Whether installed in a living area, bedroom or home office, the TX Series creates a comfortable environment for everyday living.

    Convenience is built into every aspect of the TX Series. Integrated Wi-Fi connectivity allows users to control and monitor their air conditioner remotely via the NetHome Plus App, while compatibility with Google Assistant and Amazon Alexa enables simple voice control. Features such as programmable scheduling, sleep mode and turbo operation provide greater flexibility, allowing comfort settings to be tailored to individual routines and preferences.

    Beyond temperature control, the TX Series is designed to support a healthier and more reliable home environment. A high-performance HEPA filtration system helps capture fine dust particles and reduce airborne contaminants, contributing to improved indoor air quality. Outdoors, Rinnai's GoldGuard™ protective coating enhances resistance to corrosion and oxidation, making the unit well suited to Australia's varied climates, including coastal locations.
    Smart Wi-Fi & Voice Control

    Manage comfort from anywhere with integrated Wi-Fi connectivity and the NetHome Plus App. The TX Series is also compatible with Google Home and Amazon Alexa, allowing convenient voice control and effortless adjustment of temperature, modes and schedules.

    Turbo Mode & 3D Airflow

    Turbo Mode delivers rapid heating or cooling when comfort is needed quickly, while 3D Airflow directs conditioned air both horizontally and vertically. Together, these features help achieve balanced temperatures and consistent comfort throughout the room.

    HEPA Air Filtration

    A high-performance HEPA filtration system helps create a healthier indoor environment by capturing up to 99% of dust particles and reducing airborne bacteria. Ideal for everyday living, it supports cleaner air throughout bedrooms, living spaces and home offices.

    Quiet Operation & Climate Control

    Designed for everyday comfort, the TX Series combines low-noise operation with practical climate management features. Dehumidifying Mode helps reduce excess moisture during humid conditions, while the Delay Timer allows operation to be scheduled around daily routines.
