(Check code: E3) Abnormal if indoor controller board could not find blank of transmission path.(Check code: E5) 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. (Check 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 circuit b
- 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 code(Fb): 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 code• • • • •
- P1Error codeRoom temperature thermistor (TH1) The unit is in 3-minute resume prevention mode if short/open of thermistor is detected. Abnormal if the unit does not reset normally after 3 minutes. (The unit returns to normal operation, if it has been reset normally.) 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) Suspensive abnormality, if short/open of 1 thermistor is detected for 30 seconds continuously. (The unit returns to normal operation, if it has normally reset.) Detect the following condition. 3 • During cooling and drying operation. • In case that pipe <liquid> temperature - room temperature <-10deg (Except defrosting) • When pipe <liquid> temp
- P5Error codeCompressor and indoor fan will be turned off. Drain pump is abnormal if the condition above is detected during suspensive abnormality. Constantly detected during drain pump operation | Drain pump lock protection operation Suspected abnormality, if drain pump stops for 5 seconds continuously with drain pump on. Drain pump will be restarted after turning off for 10 seconds. Drain pump is abnormal if the condition above is detected 4 times during operation.
- P6Error codeFreezing/overheating protection is (Cooling operating Freezing protection (Cooling mode) The unit is in 6-minute resume prevention mode if pipe <liquid or condenser/ evaporator> temperature stays under -15°C [5°F] for 3 minutes after the compressor started. Abnormal if it stays under -15°C [5°F] for 3 minutes again within 16 minutes after 6-minute resume prevention mode. Overheating protection (Heating mode) The units is in 6-minute resume prevention mode if pipe <condenser/evaporator> (Heating
