Utilising R32 refrigerant and high-performance DC twin-rotary inverter architecture, the AM4-H36/4DR3 achieves exceptional seasonal energy savings with an A++ rating. Long pipe run allowances of up to 80 metres total system length offer immense flexibility for intricate architectural layouts. When matched with AUX smart indoor split, cassette, or ducted units, end-users gain cloud-based climate schedules, voice command readiness, and silent low-decibel performance suited for both daytime productivity and restful sleep.
