Water tank electric heating feedback failure LC
Emergency frequent defrosting Ld
External water pump failure LE
Main water pump fault LP
1. Interface wiring disconnected.
2. There is no water in the water tank when the electric heating is started.
1. Poor connection of water pump wiring.
2. The water pump is failure,change a new water pump.
1. Poor connection of water pump wiring.
2. The water pump is failure,change a new water pump.
1. Detect the amount of refrigerant.
Err code Malfunction or protection The exclusion method
Insufficient water flow fault f L8
Auxiliary electric heating feedback failure Lb
1. Check whether the water flow switch is installed loosely.
2. Check that all shut off valves of the water circuit are completely open.
3. Check if the water filter needs cleaning.
4. Connect the water supply to the filling valves and open the valve. Filling
with some water until the manometer indicates a pressure of approximately
2.0 bar.
5. Make sure there is no air in the system (purge air).
6. Check on the manometer that there is sufficient water pressure. The
water pressure must be >1 bar(water is cold).
7. Check that the pump speed setting is on the highest speed.
8. Make sure that the expansion vessel is not broken.
9. Check that the resistance in the water circuit is not too high for the
pump.
10. If this error occurs at defrost operation (during space heating or
domestic water heating), make sure that the backup heater power supply
is wired correctly and that fuses are not blown.
11. Check that the pump fuse and PCB fuse are not blown.
1. Interface wiring disconnected.
2. There is no water in the water tank when the auxiliary electric heating is
started.
3. Check whether the temperature Controller is reset, it can be reset
manually.
Multiple master control failure C1
1. When an internal machine is connected with two line controllers, if both
line controllers are set as main line controllers, report to C1.
2. Solution: One wire controller is set as the master and the other wire
controller is set as the slave.
WiFi communication failure C7
Replace the wire controller.
Communication failure between indoor
unit and wire controller
Eb
1. Check whether there is any abnormality in the connecting line between the
line controller and the electric control board, and replace the connecting line.
2. If the wire controller is abnormal, replace it.
3. If the electric control board is abnormal, replace it.
Communication failure between indoor unit
and outdoor unit
E0
The temperature sensor in the middle of the
plate heat exchanger is faulty
E3
1. Check whether the communication wire is properly connected and in
good contact.
2. Whether there is a high magnetic field or high power
interfere, such as lifts, large power transformers, etc.. To add a barrier to
protect the unit or to move the unit to the other place.
System maintenance data abnormal E4
1. Check the temperature of the coolant tube.
2. Check the resistance of the temperature sensor.
3. The sensor connector is loose. Reconnect.
4. If the sensor is faulty, replace it with a new one.
1. Check the system maintenance function Settings.
2. Check the system maintenance data.
Outdoor temperature sensor failure E7 Check whether the temperature sensor is normal.
DIP abnormal E5
2. Check whether the cascaded models are consistent.
Exhaust temperature sensor failure E8 Check whether the temperature sensor is normal.
Outdoor current sensor failure
EA
1. Check cables to the monobloc current sensor.
2. Replace the current sensor.
3. Replace the outdoor control panel.
1. Check whether the dip switch of the model is normal.
