ERROR CODES.

When a safety device trips, an error code is displayed on the control panel (which does not include an external failure).
The table below lists all of the errors and corrective actions.
Reset the safety device by switching the unit off and back on.
If this safety device reset procedure fails, contact your local dealer.

Code
Water flow fault (after E8 has been
E0 1
displayed 3 times).
The phase loss or the neutral cable or
E1 2 the live cable are connected inversely
(only for three-phase unit).
Communication fault between the
E2 3 control panel and the hydraulic
module.
Fault of the final temperature sensor
E3 4
of the outlet water (T1).
Fault of domestic hot water storage
E4 5
tank temperature sensor (T5)
Error of the refrigerant temperature
E5 6
sensor exiting the condenser (T3).
Error of room temperature sensor
E6 7
(T4).
Fault of buffer tank temperature
E7 8
sensor (Tbt1).
Cause of fault and corrective action
1. The cable circuit is short-circuited or open. Reconnect the cable
properly.
2. The water flow rate is too low.
3. The water flow switch is faulty, the switch opens or closes continu-
ously, replace the water flow switch.
1. Check that the power cables are connected stably, to avoid the
phase loss.
2. Check the sequence of power cables, swap any sequence of two of
the three power cables.
1. The wire between the control panel and the unit is not connected.
Connect the wire.
2. The sequence of communication cables is incorrect. Reconnect the
cable in the right sequence.
3. If there is a high magnetic field or interference with high power,
such as lifts, large power transformers, etc.
4. Add a barrier to protect the unit or move the unit to another
position.
1. Check the sensor resistance.
2. The connector of sensor T1 is loose. Reconnect it.
3. The connector of sensor T1 is wet or there is water inside. Remove
the water, dry the connector. Add waterproof adhesive.
4. Fault of sensor T1, replace it with a new sensor.
1. Check the sensor resistance.
2. The connector of sensor T5 is loose. Reconnect it.
3. The connector of sensor T5 is wet or there is water inside. Remove
the water, dry the connector. Add waterproof adhesive.
4. Fault of sensor T5, replace it with a new sensor.
1. Check the sensor resistance.
2. The connector of sensor T3 is loose. Reconnect it.
3. The connector of sensor T3 is wet or there is water inside. Remove
the water, dry the connector. Add waterproof adhesive.
4. Fault of sensor T3, replace it with a new sensor.
1. Check the sensor resistance.
2. The connector of sensor T4 is loose. Reconnect it.
3. The connector of sensor T4 is wet or there is water inside. Remove
the water, dry the connector. Add waterproof adhesive.
4. Fault of sensor T4, replace it with a new sensor.
1. Check the sensor resistance.
2. The connector of sensor Tbt1 is loose. Reconnect it.
3. The connector of sensor Tbt1 is wet or there is water inside. Remove
the water, dry the connector. Add waterproof adhesive.
4. Fault of sensor Tbt1, replace it with a new sensor.
