Service-Diagnostics / Service Mode provides troubleshooting tools including alarm counters, manual 

mode, readable analog and digital inputs/outputs and other diagnostic features.

S302 HP Alarm Code C1/C2—Compressor 1 high-pressure alarm code is the left hand parameter 

and Compressor 2 is the right hand parameter: 0 = no alarm; 2 = high-pressure alarm active.
S303 HT 1 Alarm Counter—Compressor 1 high temperature event alarm counter. If more than five 

events occur in a rolling 4 hour period, then the compressor will be locked out.
S304 HT 2 Alarm Counter—Compressor 2 high temperature event alarm counter. If more than five 

events occur in a rolling 4 hour period, then the compressor will be locked out.
S305 LP Alarm Code C1/C2—Compressor 1 low-pressure alarm code is the left hand parameter and 

Compressor 2 is the right hand parameter: 0 = no alarm; 2 = low-pressure alarm active.
S306 Discharge Temp. C1—Current compressor discharge temperature reading (available only on 

compressors equipped with discharge temperature thermistors).
S307 Discharge Temp. C2—Current compressor discharge temperature reading (available only on 

compressors equipped with discharge temperature thermistors).
S308 Actual LP1 /LP2 Pressure—Current low side refrigerant pressure reading in gauge for 

Compressor 1 on the left hand side and Compressor 2 on the right.
S309 Actual HP1/HP2 Pressure—Current liquid line refrigerant pressure reading in gauge for 

Compressor 1 on the left hand side and Compressor 2 on the right (available only on water-cooled or 

glycol units equipped with motorized ball valves).
