Probable cause Remedy
Waiting for compressor delay timer Check CoP->CSt
Line voltage to compressor too low or too high Check CoP->uLi, uLo, uHi
E01: Sensor "S1" defective
Replace sensor
E02: Sensor "S2" defective
Condenser temperature exceeds the Clean condenser,
temperature set in condenser settings menu Check Con->CAL, CbL
Temperature too high Check ALA->HAt
Temperature too low Check ALA-> LAt
