code meaning LED2 remark
E1 compressor overheat or discharge
high temp protection
red and flash Decided by outdoor unit
E2 Outdoor air temp sensor error Flash 3 times Outdoor air temp sensor open circuit or short circuit
E3 pipe or return air temp sensor error Flash 6 times (1)temp sensor open circuit or short circuit
(2) suck sensor open or short circuit
E4 AC return water temp sensor error red and flash Stop compressor when running AC
E5 AC leaving water temp sensor error red and flash Stop compressor when running AC
E6 DHW temp sensor error red and flash Stop compressor when running AC
E7 solar water temp sensor error As normal Not stop compressor
E8 fan coil high temp protection red and flash Water source anti freeze protection
E9 system anti freeze twice red and flash Stop compressor
EA DHW anti freeze twice red and flash Stop compressor
EB indoor refrigerant pipe sensor error No flash Temp sensor open circuit or short circuit
EC water source inlet water sensor error No flash Temp sensor open circuit or short circuit
ED water source leaving temp sensor No flash Temp sensor open circuit or short circuit
EE water source anti freeze protection No flash 1.Water source heat exchange not efficient or water source temp
too low 2.Water source water flow volume not enough
EF water source water flow not enough No flash Water source water flow volume not enough
EG Indoor ambient sensor error No flash Temp sensor open circuit or short circuit
F1 aaavoltage protection Flash 1 time Voltage is too high or too low, heat pump will recover when
voltage be normal (165~265VAC)
F2 power module PFC error Red and flash IPM module error or wire connection wrong
F3 compressor abnormal stop Red and flash compressor stops abnormally
F4 outdoor module radiator sensor error Flash 5 time Temp sensor open circuit or short circuit
F5 outdoor current sensor error Flash 8 time Current sensor fault or no test wire cross it
F6 IPM error or Module control board
error Red and flash Communication not good or IPM module fault
F7 compressor fail to start up Red and flash Compressor cannot start properly
F8 outdoor over current Red and flash
Compressor current is too high
F9 Discharge sensor error Flash 7 time Temp sensor open circuit or short circuit
FA Outdoor module overheat, over
current Flash 5 time IPM module temp too high or compressor current too
high
FB
/E8 outdoor coil over heat Flash 15 time Outdoor heat exchange not good
P1 high pressure protection Flash 2 time 1.refrigerant volume too much 2.throtting part error, 3. High
pressure switch error
P2 low pressure protection Flash 9 time 1.refrigerant volume too little 2.throtting part error, 3. low
pressure switch error
P3 compressor discharge air over heat
protection Flash 10 time 1.Refrigerant too little, 2.throtting part error
P4 over current protection Flash 11 time 1.refrigerant volume too much 2.throtting part error, 3. Current
sensor error
P5 indoor unit water flow error No flash 1.Water flow volume too small 2. Water flow switch error
P6 outdoor water flow error ( For GH) Flash 17 time 1.Water source side waterflow volume too small 2. Water
source side Water flow switch error
P7 miss phase Red and flash Power supply error
P8 wrong phase Red and flash power supply error
P9 communication error Red and flash Communication wire open or PCB error
