- E3Error codeRemote controller transmission error(E3)/signal receiving error(E5) 1 Abnormal if remote controller could not find blank of transmission path for six seconds and could not transmit. (Error code: E3) 2 Remote controller receives transmitted data at the same time, compares the data, and when detecting it, judges different data to be abnormal 30 continuous times. (Error code: E3) 1 Abnormal if indoor controller board could not find blank of transmission path. (Error code: E5) 2 Indoor controller bo
- E4Error coderemote controller board or from other indoor controller board for three minutes. (Error code: E4) 2 Indoor controller board cannot receive any signal from remote controller for two minutes. (Error code: E4)
- E5Error code1 Abnormal if indoor controller board could not find blank of transmission path. (Error code: E5) 2 Indoor controller board receives transmitted data at the same time, compares the data,and when detecting it, judges different data to be abnormal 30 continuous times. (Error code: E5)
- E6Error codeIndoor/outdoor unit communication error (Signal receiving error) 1. Abnormal if indoor controller board cannot receive any signal normally for six minutes after turning the power on. 2. Abnormal if indoor controller board cannot receive any signal normally for three minutes. 3. Consider the unit as abnormal under the following condition: When two or more indoor units are connected to an outdoor unit, indoor controller board cannot receive a signal for three minutes from outdoor controller circui
- E7Error codeIndoor/outdoor unit communication error (Transmitting error) Abnormal if “1” receiving is detected 30 times continuously though indoor controller board has transmitted “0”.
- FBError codeAbnormality of indoor controller board Abnormal if data cannot be normally read from the nonvolatile memory of the indoor controller board.
- FHError codeRefrigerant sensor error Abnormal if refrigerant sensor cannot detect errors normally.
- FLError codeRefrigerant leakage Abnormal if refrigerant leakage detected by a refrigerant sensor.
- P1Error codeRoom temperature thermistor (TH1) 1. The unit is in three-minute resume prevention mode if short/open of thermistor is detected. Abnormal if the unit does not reset normally after three minutes. (The unit returns to normal operation, if it has normally reset.) 2. Constantly detected during cooling, drying and heating operation Short: 90°C[194˚F] or more Open: -40°C[-40˚F] or less

Constantly detected during cooling, drying, and heating (except defrosting) operation.
- P4Error codeAbnormality of drain sensor (DS) 1 Suspensive abnormality, if short/open of thermistor is detected for 30 seconds continuously. (The unit returns to normal operation, if it has normally reset.) 3 Detect the following condition. • During cooling and drying operation. • In case that pipe <liquid> temperature - room temperature <-10deg (Except defrosting) • When pipe <liquid> temp
- P5Error codeSuspensive abnormality, if drain float switch is detected to be underwater for 1 minute and 30 seconds continuously with drain pump on. 2. Drain pump is abnormal if the condition above is detected during suspensive abnormality. 3. Constantly detected during drain pump operation.
