The ECO-i™ three-way line, which offers heat recovery, gives the user the ability to simultaneously heat and cool different zones. According to the manufacturer, this series offers the same features as the two-way line and even higher energy savings. Because a single refrigerant pipe network is used, only one penetration into the building is needed and less piping material is required, saving time and money. Models include CHDZ09053, CHDZ14053, WCHDZ0053, WCHDZ26053, and WCHDZ32053. All models offer flexible combinations, inverter control compressors, and high energy efficiencies.
