- 5701Error codeContact failure of drain float switch (CN4F) Extract when the connector of drain float 1 switch is disconnected. (3 and 4 of connector CN4F is not short-circuited.) 2 Constantly detected during operation.
- E0Error codeRemote controller transmission error(E0)/signal receiving error(E4) 1 Abnormal if main or sub remote controller can not receive normally any transmission from indoor unit of refrigerant address “0” for three minutes. (Error code : E0) 2 Abnormal if sub remote controller could not receive for any signal for two minutes. (Error code: E0) 1 Abnormal if indoor controller board can not receive normally any data from remote controller board or from other indoor controller board for three minutes.
- E1Error codeAbnormality of remote controller control board 1 Abnormal if data cannot be normally read from the nonvolatile memory of the remote controller control board. (Error code: E1)
- 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 codeindoor 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 putting the power on. 2 Abnormal if indoor controller board cannot receive any signal normally for three minutes. 3 Consider the unit abnormal under the following condition: When two or more indoor units are connected to one outdoor unit, indoor controller board cannot receive a signal for three minutes from outdoor controller circuit boa
- 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.
- P1Error codeRoom temperature thermistor (TH1) The unit is in three-minute resume 1 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
- P2Error codePipe temperature thermistor/Liquid (TH2) 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 (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 code2 Drain pump is abnormal if the condition above is detected during suspensive abnormality. 3 Constantly detected during drain pump operation.
- P6Error codeFreezing/overheating protection is working 1 Freezing protection (Cooling mode) The unit is in six-minute resume prevention mode if pipe <liquid or condenser/evaporator> temperature stays under -15: for three minutes, three minutes after the compressor started. Abnormal -15: if it stays under for three minutes again within 16 minutes after six-minute resume prevention mode. <Frost prevention mode> If pipe <liquid or condenser-evaporator> 2: temperature is or below when 16 minutes has passed afte
- P8Error codeAbnormality of pipe temperature <Cooling mode> Detected as abnormal when the pipe temperature is not in the cooling range 3 minutes later of compressor start and 6 minutes later of the liquid or condenser/evaporator pipe is out of cooling range. Note 1) It takes at least 9 min. to detect. Note 2) Abnormality P8 is not detected in drying mode.
- P9Error codeAbnormality of pipe temperature thermistor / Condenser-Evaporator (TH5) 1 The unit is in three-minute resume protection mode if short/open of thermistor is detected. Abnormal if the unit does not get back to normal within three minutes.
- PAError code(Drain pump will start operating when the drain sensor is detected to be soaked in the water.) 2 The unit has a water leakage abnormality when the following conditions, a and b, are satisfied while the above-mentioned detection is performed. a) The drain s
