When a safety device is activated, an error code will be displayed on the user interface.
A list of all errors and corrective actions can be found in the table below.
Reset the safety by turning the unit OFF and back ON.
In case this procedure for resetting the safety is not successful, contact your local dealer.
13.4 Error codes
The power consumption parameter is preparatory. some parameter is not be activated in the system, the parameter will
show "--"
The heat pump capacity is for reference only, not used to judge the ability of the unit. The accuracy of sensor is ±1

MALFUNCTION
OR PROTECTION
FAILURE CAUSE
AND CORRECTIVE ACTION
Water flow fault (E8
displayed 3 times)
1.The wire circuit is short connected or open. Reconnect the wire
correctly.
2.Water flow rate is too low.
3. Water flow switch is failed, switch is open or close continuously,
change the water flow switch.
Phase loss or neutral wire and
live wire are connected
reversely
1.Check the power supply cables should be connected stable, to avoid
phase loss.
2.Check the power supply cables sequence, change any two cables
sequence of the three power supply cables.
Communication fault between
controller and main control
board of hydraulic module
’
1.The wire doesn’t connect between wired controller and unit. connect
the wire.
2.Communication wire sequence is not right. Reconnect the wire in
the right sequence.
3. Whether there is a high magnetic field or high power interfere, such
as lifts, large power transformers, etc..
4. To add a barrier to protect the unit or to move the unit to the other
place.
Final outlet water temp. sensor
(T1) fault.
1. Check the resistance of the sensor
2. The T1 sensor connector is loosen. Reconnect it.
3.The T1 sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive.
4.The T1 sensor failure, change a new sensor.
Water tank temp. sensor
(T5) fault.
1. Check the resistance of the sensor
2.The T5 sensor connector is loosen. Reconnect it.
3.The T5 sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive
4.The T5 sensor failure, change a new sensor
