arcing that can destroy the electronic
components.

7.1
Recognising errors, correcting
malfunctions
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 section 7.3).
– shows information messages regarding the operating status
(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.

7.1.3 Troubleshooting
Information messages, which are displayed
without red back-
lighting
, normally result in
no permanent limitations
on the op-
eration of the Daikin RoCon.
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 7.3.
●
Detecting and remedying the cause of the malfunction.
– Contactor triggered:
Nothing shown on the display in the controller. Ascertain
cause of triggering the contactor and remedy fault. Start up
system again.
Once the cause has been remedied, the system will
resume operations as normal.
– Contactor not triggered:
a) No fault codes are shown but the system is not working
properly. Troubleshooting and eliminating faults
(see section 7.3).
Once the cause has been eliminated, the system contin-
ues to work normally.
b) Fault codes are displayed as long as the fault conditions
are present. Troubleshooting and eliminating faults
(see section 7.3). If the fault message is still displayed
after the cause of the fault has been corrected, the system
must be disconnected fromthe power supply for at least
10 in order to unlock it.
Once the cause has been eliminated, the system contin-
ues to work normally.
