Affinityâ„¢ 3S and 8T Series 13- and 15-SEER heat pumps have hot heat pump technology, which produces discharge temperatures warmer than the discharge temperatures of standard heat pumps, claims the company. The 8T is engineered with the Ultratechâ„¢ compressor, part of the QuietDriveâ„¢ system. This system has a swept-wing fan design, isolated compressor compartment, composite base pan, and two-stage cooling. The heat pumps have a demand defrost board that features service analyzer capabilities, integrated control, fault code retention, hot heat pump and fossil fuel jumpers, and high- and low-pressure switch connections. Features include a choice of exterior colors, metal coil guard, polymer mesh for coil protection, and isolated compressor compartment.
