Pioneer Air Conditioner WYS030GMHI22M3

They provide totally decentralized and independent zone control for the perfect climate in each zone or room. Each zone can be individually and independently set to be on or off or to run with different temperature settings. Indoor units automatically adjust their capacities up to and down in real-time and as needed to match the zone's cooling or heating loads. The outdoor unit will also adjust its total output based on the total demand it receives from all simultaneously running indoor units in real-time. This function results in significant energy savings. Systems use single-point power entry to the outdoor unit only and indoor units receive their power from the outdoor unit.
