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°C.
The flow rates parameters are calculated according to the pump running parameters,the deviation is different at different
flow rates,the maximum of deviation is 25%.
13.4 Error codes
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.

NOTE
FAILURE CAUSE AND CORRECTIVE ACTION
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.
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.
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.
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.
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
