Error Codes - Immergas MAGIS M4-30 Use And Installation

ERROR CODES.

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

Operation or protection anomaly
Water ow fault (a er E8 has been
displayed 3 times).
e phase loss or the neutral cable or
the live cable are connected inversely
(only for three-phase unit).
Communication fault between the
control panel and the hydraulic
module.
Fault of the nal temperature sensor
of the outlet water (T1).
Fault of domestic hot water storage
tank temperature sensor (T5)
Error of the refrigerant temperature
sensor exiting the condenser (T3).
Error of room temperature sensor
(T4).
Fault of buffer tank temperature
sensor (Tbt1).
Cause of fault and corrective action
1. e cable circuit is short-circuited or open. Reconnect the cable
properly.
2. e water ow rate is too low.
3. e water ow switch is faulty, the switch opens or closes continu-
ously, replace the water ow 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. e wire between the control panel and the unit is not connected.
Connect the wire.
2. e sequence of communication cables is incorrect. Reconnect the
cable in the right sequence.
3. If there is a high magnetic eld or interference with high power,
such as li s, 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. e connector of sensor T1 is loose. Reconnect it.
3. e 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. e connector of sensor T5 is loose. Reconnect it.
3. e 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. e connector of sensor T3 is loose. Reconnect it.
3. e 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. e connector of sensor T4 is loose. Reconnect it.
3. e 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. e connector of sensor Tbt1 is loose. Reconnect it.
3. e 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.
