part.
3. main control board of indoor unit is broken, change a new
PCB.
Indoor unit EEprom failure
1.wire doesn’t connect between outdoor unit and main control
board of indoor 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.. To add a
barrier to protect the unit or to move the unit to the other place.
Communication fault between
indoor unit and outdoor unit
1.Check the resistance of the sensor
2. The T1B sensor connector is loosen. Reconnect it.
3.The T1B sensor connector is wet or there is water in.
Remove the water, make the connector dry. add waterproof
adhesive
4. The T1B sensor failure, change a new sensor.
Outlet water for zone 2
temp.sensor (Tw2) fault
1. The TW_out sensor connector is loosen. Reconnect it.
2.The TW_out sensor connector is wet or there is water in.
remove the water, make the connector dry. add waterproof
adhesive
3. The TW_out sensor failure, change a new sensor.
Outlet water
temp.sensor(Tw_out)
fault
1.Check the resistance of the sensor
2. The Ta senor is in the interface;
3. The Ta sensor failure
，
change a new sensor or change a
new interface, or reset the Ta, connect a new Ta from the
indoor unit PCB
Room temp.sensor(Ta) fault
1.Check the resistance of the sensor
2.The T2 sensor connector is loosen. Re connect it.
3.The T2 sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive
4. The T2 sensor failure, change a new sensor.
Refrigerant liquid
temp.sensor(T2) fault
1.Check the resistance of the sensor
2. The T2B sensor connector is loosen. Reconnect it.
3.The T2B sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof adhesive
4. The T2B sensor failure, change a new sensor.
Refrigerant gas
temp.sensor(T2B) fault
1. Check that all shut off valves of the water circuit are
completely open.
2. Check if the water filter needs cleaning.
3. Refer to "8.6 Filling water"
4. Make sure there is no air in the system (purge air).
5. Check on the manometer that there is sufficient water
pressure. The water pressure must be >1 bar(water is cold).
6. Check that the pump speed setting is on the highest speed.
7. Make sure that the expansion vessel is not broken.
8. Check that the resistance in the water circuit is not too high
for the pump. (refer to "9.4 Setting the pump" ).
|Tw_out - Tw_in| value too

Anti-freeze mode
1.Check the resistance of the two sensor
2.Check the two sensors locations
3.The water inlet/outlet sensor wire connector is loosen.
Reconnect it.
4.The water inlet/outlet
（
TW_in /TW_out
）
sensor is broken,
Change a new sensor.
5. Four-way valve is blocked. Restart the unit again to let the
valve change the direction.
6.Four-way valve is broken, change a new valve.
Unit will return to the normal operation automatically.

CAUTION
In winter, if the unit has E0 and Hb failure and the unit is not repaired in time, the water pump and pipeline system
may be damaged by freezing, so E0 and Hb failure must be repaired in time.

Communication error
between main board and
thermostat transferboard
RT/Ta PCB is set to be valid on user interface but the
thermostat transfer board is not connected or the
communication between thermostat transfer board and
main board is not effectively connected. If the thermostat
transfer board is not needed
，
set the RT/Ta PCB to invalid.
If the thermostat transfer board is needed
，
please connect
it to the main board and make sure the communication wire
is connected well and there is no strong electricity or strong
magnetic interference.
1.Check the resistance of the sensor.
2.The Tbt2 sensor connector is loosen,reconnect it.
3.The Tbt2 sensor connector is wet or there is water in,remove
the water ,make the connector dry.Add waterproof adhesive.
4.The Tbt2 sensor failure,change a new sensor."
