Select 10K or 20K based on the sensor
installed. Refer to resistance values below:
50062329-001 = 10K ohm
32005180-002 = 10K ohm
C7735A1000 = 10K ohm
C7770A = 20K ohm
C7041 = 20K ohm

5110 A-Coil Low
Temperature Cutoff
Off
35° F to 65° F (in 5° F increments) Off Both Yes If an optional Discharge Air Temperature
sensor is used, this feature can help
prevent icing on the air conditioning A-Coil.
When temperature reaches the limit you
set, compressor(s) will shutoff while the
system fan continues to run, until the
temperature rises to a safe level.
