Advanced Technology Compressor Occupants enjoy balanced, consistent comfort because the operating sequence of the outdoor units and the individual compressors are rotated to spread operating hours evenly. Because the compressors are all Inverter-driven, inrush currents are eliminated. There is no on/off power surge as the system adjusts to the demands of the occupant or system. And, the use of Inverter compressors reduces the risk of compressor failure, more common in standard non-Inverter systems. The outdoor unit provides greater backup capability in case of a compressor failure. If that happens,...
