Fault Handling
When the system is
turned on or working, the
wired controller displays
code "E5" and the buzzer
alarms the fault.
2. Confirm whether the power supply and
fan voltage meet the design
requirements.
1. The fan assembly, controller damage or
line failure, causing the fan not to run or
the speed is too low, check the fan, the
main controller is damaged, the wiring
is damaged, loose, replace the damaged
parts.
Possible Cause
1. The fan signal is not detected or the
speed is too low in the system startup
5S.
2. During operation, the fan speed is not
detected for 2S consecutively, or the
speed is too low.
3. The power supply voltage is too low,
causing the fan speed to slow down.
During the system
working process, the
wired controller displays
code "E6" and the buzzer
alarms the fault.
3. Test whether the actual water outlet
temperature and the wired controller
display temperature are close(±3 °C),
and replace the wrong outlet water
temperature sensor.
5. Detect if the heat exchanger fins are
poorly welded and replace the damaged
parts.
4. Check the combustion system for
damage and replace damaged parts.
2. Check whether the program and
parameters meet the values of the
parameter table.
1. Confirm that the gas type and pressure
meet the requirements of the water
heater.
2. The control program or parameter
settings are incorrect, resulting in
abnormal combustion.
1. The gas supply pressure or gas
composition does not match, causing
abnormal combustion.
5. The heat exchanger fins of the heat
exchanger are poorly welded, and the
heat transfer is slow. After the water
valve is closed, the water in the tube is
continuously heated.
4. The combustion system is damaged or
the specifications are inconsistent,
resulting in abnormal combustion.
3, The water temperature sensor
specifications do not match, the display
temperature is much higher than the
actual temperature.
When the system is
turned on or working, the
wired controller displays
"E7" and the buzzer
alarms the fault.
1. Clamp the water temperature sensor
terminal.
2. Check if the valve coil is short- circuited
and replace the damaged parts.
1. The valve connector is loose or has poor
contact.
2. The valve is short-circuited.
When the system is
turned on or working, the
wired controller displays
code “E4" and the buzzer
alarms the fault.
1. Clamp the water temperature sensor
terminal.
2. Replace the water temperature sensor. 2. The inlet water temperature sensor is
damaged (open circuit, short circuit or
metal parts).
1. The inlet water temperature sensor
connector is loose or has poor contact.
When the system is
turned on or working,
the wired controller
displays code "E3" and
the buzzer alarms the
fault.
2. Confirm that the gas type and pressure
meet the requirements of the water
heater.
1. Check the temperature controller or
circuit and replace the damaged parts.
4. Check the combustion system for
damage and replace damaged parts.
3. Check whether the program and
parameters meet the values of the
parameter table.
1. The thermostat opens or the wire is
faulty.
2. The gas supply pressure or gas
composition does not match, causing
abnormal combustion.
3. The control program or parameter
settings are incorrect, resulting in
abnormal requirements combustion.
4. The combustion system is damaged or
the specifications are inconsistent,
resulting in abnormal combustion.
