Error Codes

Cause
• Incorrect connection between
sensor and PCB(Heater).
• PCB(Heater) fault
• Sensor fault
Restriction of BLOC Water pump
• Incorrect connection between
sensor and PCB(Heater)
• PCB(Heater) fault
• Sensor fault
• The connector for transmission is
disconnected
• The connecting
wires are
misconnected
• The communication line is broken
• Main PCB assembly(lnverter) is
abnormal
• Main PCB assembly(Heater) is
abnormal
• Electrical or mechanical damage a
the EEPROM
• Flow switch is open
while internal
water pump is working
• Flow switch is closed
while internal
water pump is not working
• Flow switch is open
while DIP
switch No. 5 of Main PCB
assembly(Heater) is set as on
• Abnormal operation of electric
heater
• Leaving
water temperature is
above 72 °C.
Normal Condition
• Resistance: 10 kO at 25 centigrade
(unplugged) -+ for Remote room air
sensor
• Resistance: 5 kO at 25 centigrade
(unplugged)-+ for all sensors EXCEPT
remote room air sensor
• Voltage: 2.5
V DC at 25 centigrade
(plugged) (for all sensors)
• Refer resistance-temperature table to
check in different temperature
• BLOC Water pump defect/
assembly condition abnormal
• Fan lock by foreign material
• Wire connection between remote
controller and Main PCB
assembly(Heater) should be tight
• Output
voltage of PCB should be 12 V
DC
• Wire connection between remote
control panel and Main PCB
assembly(Heater) should be tight.
• This error can not be permitted
• Flow switch should be closed
internal water pump is working
switch No. 5 of Main PCB
assembly(Heater) is set as on
• Flow switch should be open
internal water pump is not
• If there is no problem in electric heater
control, possible maximum leaving
water temperature is 72 °C
