The NetHome Plus App provides full Wi-Fi control, letting you turn the system on, adjust temperature, or change modes remotely.
High Efficiency Inverter
The advanced 3D DC inverter system uses three synchronised DC motor technologies to deliver faster response, lower energy consumption, and quieter performance compared to conventional air conditioning units. This ensures steady comfort in all weather conditions.
DRED Capability
The Rinnai 18kW MON6H18B Multi-Split air conditioner is Demand Response Enabled (DRED), allowing communication with your electricity retailer to reduce energy use during peak demand. This feature enhances grid sustainability and lowers operational costs.
Operating range and Reliability
Built for Australia’s diverse climate, the Rinnai Multi-Split unit operates from –15°C to 50°C with excellent defrost control for reliable low-temperature performance.
