Parameter Name Description
NO ALARM No alarms active, everthing is running correctly
PRESSURE SENSOR Suction pressure sensor is shorted, open or pressure out of range
SUCTION TEMP SENSOR Suction temperature sensor is shorted or open
AIR TEMP SENSOR Return air temperature sensor is shorted or open
COIL TEMP SENSOR Coil temperature sensor is shorted or open
AUX TEMP SENSOR Auxiliary temperature sensor is shorted or open
HIGH SUPERHEAT Superheat above upper limit
LOW SUPERHEAT Superheat below lower limit
HIGH AIR TEMP Room temperature is above ROOM TEMP + AIR TEMP DIFF + HIGH TEMP ALARM OFFSET for longer than HIGH TEMP ALARM DELAY
LOW AIR TEMP Room temperature is below ROOM TEMP - LOW TEMP ALARM OFFSET for longer than LOW TEMP ALARM DELAY
EXCESS DEFROST Three consecutive defrosts with less than a one hour interval between each defrost
DEFR TERM ON TIME Defrost terminated on time instead of temperature for two consecutive cycles
DOOR SWITCH If door is open and room temperature is 5 degrees above ROOM TEMP + AIR TEMP DIFF for DOOR ALARM DELAY time
COMMUNICATION ERROR ONLY FOR BONDED CONTROLLERS: No communication between controllers for one minute or more
EXT ALARM If DIG IN (1, 2 and/or 3) MODE = EXT ALARM: The digital input is in an active state
