LennoxPROs® LB-101123C 1087352

The low ambient control pressure switch S11 cycles the outdoor fan, while allowing continuous compressor operation during a cooling demand. This intermittent outdoor fan operation maintains a minimum pressure differential across the expansion device as the ambient temperature drops, thus reducing capacity losses during low ambient conditions. The freezestat (ordered separately) senses suction line temperature and cycles the compressor off when suction line temperature falls below its set point. This kit is designed for use in ambient temperatures that are no lower than 30 deg F unless otherwise noted in the product specification bulletin.
