Wide opeation range (-10~43℃); 360° wide-angle airflow， ceiling height of 3.5 m;

Defrosting self-adapting: The system can precisely determine when to start defrosting based on system running duration, compressor suction and exhaust pressure, ambient temperature, outdoor heat exchanger coil temperature, and last defrosting data. When there is a need for defrosting, the defrosting operation will be started. When there is not such a need, the system will keep the heating operation. This guarantees the optimum heating capacity and ultra-high energy efficiency of the unit. Anti-frosting at the bottom: In defrosting mode, the one-way valve at the bottom is closed to ensure thorough defrosting at the unit bottom and avoid degraded performance due to frosting at the bottom.
