Product Overview

Lennox LB-101123B, Low Ambient Control Kit, For PSC Fan Heat Pump Units

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 setpoint. This kit is designed for use in ambient temperatures that are no lower than 30°F (-1°C) unless otherwise noted in the Product Specification bulletin.
NOTE - This kit may be applied in expansion valve systems only. It is not suitable for use in systems using either piston-type or capillary tube metering devices.
NOTE - This kit is suitable only for use with heat pump units in HFC-410A refrigerant applications.

Includes:

  • Low ambient pressure switch assembly (S11)
  • K58 relay
  • (4) 20” Lengths of wire (c/w 3/16” Female quick connects on one end of wire)
  • (4) Wire nuts
  • (2) #10-16 X 5/8” S.D.S.T. screws
  • Schrader® depressor tee with seal cap
