Cause
During normal operation, if an anomaly causes excessive
overheating of the flow temperature in the mixed zone 2,
the unit indicates the malfunction.
During normal operation, if an anomaly causes excessive
overheating of the flow temperature in the mixed zone 3,
the unit indicates the malfunction.
This occurs when the power supply voltage is lower than the
allowed limits for correct system operation.
During normal operation, if an anomaly causes excessive
overheating of the flow temperature in zone 1, the unit indi-
cates the malfunction.
In the event the external probe is not connected or is faulty,
the anomaly is indicated.
The central heating storage tank has an out of range resis-
tive value
If the board detects an anomaly on the mixed zone 1 probe,
the system cannot work in the affected area.
The device connected to zone 1 is offline
The device connected to zone 2 is offline
The device connected to zone 3 is offline.
The zone 1 room probe has an out of range resistive value
The zone 2 room probe has an out of range resistive value
Indoor unit status / Solution
The unit does not meet the zone
central heating requirement. (1)
The unit does not meet the zone
central heating requirement. (1)
If normal conditions are restored, the
system restarts without having to be
reset (1)
The unit does not meet the zone
central heating requirement (1).
Check the external probe connection.
The system continues to operate with
the external probe integrated in the
external unit (1).
In case of replacement of the external
probe, repeat the installation opera-
tions.
Puffer mode is disabled. (1)
