Reason for fault code being triggered
At least two assemblies with the same bus ID are
present on the bus system
The thermistor protection relay for the compressor
has been triggered.
Oil compensation valve does not open/close.
Minor inverter fault: Communication between sig-
nal processor and main processor is faulty.
Minor inverter fault: Communication between sig-
nal processor and main processor is faulty.
Minor inverter fault: Temperature sensor fault, scroll
temperature below the permissible range.
Minor inverter fault: Temperature sensor fault,
motor temperature below the permissible range.
Minor inverter fault: Temperature sensor fault, inter-
nal switching circuit temperature below the permis-
sible range.
Minor inverter fault: Temperature sensor fault, in-
verter IGBTs below the permissible range.
Minor inverter fault: Temperature sensor fault, PFC
IGBTs below the permissible range.
Minor inverter fault: Inverter fault limit has been
achieved and inverter was interlocked.
High relevance communication objects have been
incorrectly transferred repeatedly between the IWS
and inverter.
The defined minimum source temperature was not
reached.
Incorrect communication with the WPM.
Sensor value of the "FE 7" outside the permissible
range
FES version conflict
WPE version conflict
FET version conflict
WPM version conflict
Limiter communication interruption IWS/CWS
MFG sensor value of the "HP return temperature"
outside the permissible range.
MFG sensor value of the "HP flow temperature" out-
side the permissible range.
MFG sensor value of the "HP flow rate" outside the
permissible range.
Incorrect communication with the HP return tem-
perature sensor in the MFG.
Incorrect communication with the HP flow tempera-
ture sensor in the MFG.
Incorrect communication with the heating circuit
flow rate sensor in the MFG.
Float switch has been triggered
MFG sensor value of the "HP return temperature"
outside the permissible range
MFG sensor value of the "HP flow temperature" out-
side the permissible range
MFG sensor value of the "NHZ flow temperature"
outside the permissible range
MFG sensor value of the "DHW temperature" out-
side the permissible range
Possible cause of fault / remedy
Remove the cause. Then carry out a WPM reset.
The intermediate injection is faulty.
The thermistor chain has been interrupted.
The expelled air fan is faulty.
The compressor has an interwinding fault.
The motor overload relay is faulty.
Remove the cause. Then carry out a WPM reset.
Check leads and the relevant plug-in connectors,
and replace if faulty.

Inverter fault
Inverter fault. Check leads and the relevant plug-in
connectors, and replace if faulty. Check the power
supply to the inverter.
Check the minimum source temperature and
change it if required. Check source flow rate: Check
source sizing.
Check the communication cable terminal or replace
the communication cable.
Check sensor, leads and the relevant plug-in con-
nectors, and replace if faulty. Terminal: WPM X 1.13
The FES software needs updating. Run the update.
The WPE software needs updating. Run the update.
