Significantly greater efficiency is realized by using DC twin rotary compressor, all DC inverter technology, and large heat exchanger.
Improvement and design flexibility has allowed multiple fan speeds and static pressure modes. Low noise is realized by adopting plastic case, plastic fan.
A low outdoor noise operation mode allows the outdoor unit to have two quiet mode operation settings.
A peak power consumption mode controls a 4 step outdoor operation control to cut down energy usage at peak energy usage times.
