Unit Controller Inputs
8 Compressor #1 Low Pressure Switch
Switch Closed (1) Low Pressure Switch for compressor #1 is normal
Switch Open (0) Low Pressure Switch for compressor #1 is in alarm
9 Compressor #1 High Pressure Switch
Switch Closed (1) High Pressure Switch for compressor #1 is normal
Switch Open (0) High Pressure Switch for compressor #1 is in alarm
