Code Description
E0 Error of sensor T5U (upper water temperature sensor)
E1 Error of sensor T5L(lower water temperature sensor)
E2 Storage tank and Wired Controller communication error
E4 Evaporator temperature sensor T3 error
E5 Ambient temperature sensor T4 error
E6 Compressor discharge temperature sensor TP error
Electric leakage error
If PCB current_induction_circuit check the current
E8
difference between L,N >14mA, system consider it as
"electric leakage error"
E9 Compressor suction temperature sensor TH error
E-heater open-circuit error IEH (Current difference E-
EE
heater on and off )<1A
EF Clock chip error
Ed E-EPROM chip error
