When the water tank or ambient temperature sensor are faulty, electric heating
operation is not allowed. “11E”, “12E”, “13E” ", "14E", "15E", "17E", "18E", "19E". are
correspondingly displayed when the coil temperature sensor, ambient temperature
sensor, exhaust temperature sensor, inlet water temperature sensor/tank temperature
sensor, absorb temperature sensor, and outlet water temperature sensor/return water
temperature sensor are faulty.
•
“09E” is displayed when the communication between the main control board and the
wire controller is abnormal or the data line is not connected normally. “--:--” is
displayed when the valid clock cannot be obtained.
•
The communication indicator of the main control board flashes.
•
The buzzer sounds when an alarm occurs.
•
Press any key to silence the alarm.
The fault code table is as follows:
