8 Errors, malfunctions and messages
8.1 Deleting errors, correcting malfunctions,
deleting messages
Electronic control of the Daikin Altherma EHS(X/H):
– signals an error by means of the background of the display
lighting up red and shows an error code in the display (see
Installation and Maintenance Instructions).
– shows information messages regarding the operating status,
which is not signalled by red background lighting.
An integrated Protocol saves up to 15 error related or other infor-
mation messages regarding the operating status that last oc-
curred.
Depending on the operating mode, messages are also forwarded
to connected room stations or room thermostats.
8.1.1 Current fault display
8.1.2 Read Protocol
The Protocol can be read in the "Special Level" (see fig. 8-3).
The last received (latest) message is in the first position. All other
previous messages are then pushed backwards by one place
when a new entry is made. The 15th message will be deleted any
time a new message is received.
8.1.3 Troubleshooting
In section 8.2 conceivable faults and their possible causes are
listed. Tips to correct the faults are also provided.
Information messages, which are displayed without red back-
lighting , normally result in no permanent limitations on the op-
eration of the Daikin Altherma EHS(X/H).
Messages that are displayed with an error code E.... and red
back-lighting required error correction by an authorised and
trained expert heating technician .
For information on warning messages see section 8.3.

Once the cause has been eliminated, the system contin-
ues to work normally.
