2. More comfort

Powerful heating

Advanced heat-pump technology improves heating capacity at low outdoor temperatures. The promotional comparison shows up to 33% higher heating output than the previous 6 HP-class model under the illustrated low-temperature condition.

Sales message: Position J-II for colder regions and buildings where dependable winter performance is a key selection criterion.

Low-noise design

The optimised outdoor-unit fan and airflow structure reduce sound levels. The 6 HP J-II promotional rating is shown at 53 dB(A), compared with 56 dB(A) for the previous model. A selectable low-noise mode can reduce rated sound levels by approximately 5 to 8 dB, depending on the operating condition.

3. Easy installation

Automatic address setting: Indoor-unit addresses can be assigned automatically from the outdoor unit, reducing manual setup and the risk of addressing errors.
Connection check function: The outdoor-unit display identifies connected indoor units and can show duplicated addresses and the number of indoor units connected.

These functions streamline commissioning, support faster verification and help reduce avoidable return visits caused by setup or wiring issues.
