8 Faults and malfunctions
DANGER: RISK OF ELECTROCUTION
Electrostatic charges can lead to voltage arcing that can
destroy the electronic components.
▪ Ensure potential equalisation prior to touching the
switching panel PCB (e.g. by touching the switching
panel holder).
The electronics of the Daikin Altherma ETS(X/H) indicate an error by
red illumination of the status display, the appearance of the error
screen on the display (see
Chap. 8.4 ) and the appearance of the er-
ror symbol on the start screen. An integrated error memory stores up
to 15 error messages (see
Chap. 8.3 ).
INFORMATION
A list of all error codes can be found in the Daikin Altherma
ETS(X/H) installation and maintenance instructions,
chapter "Errors, malfunctions, messages".
Troubleshooting: Error code E90XX
An error reset can be performed. This can be started from the cur-
rently displayed error screen. If the error screen has been exited, it
can be recalled via [→ Main menu → Error → Screen].
If the same error is displayed again shortly, the cause of the error
must be found and rectified by a specialist. In the meantime, emer-
gency operation may be maintained. Emergency operation can be
permitted via [→ Main menu → Error → Emergency], see
Chap. 8.1 .
If emergency operation has not been permitted, it can be started
from the current error screen.
Troubleshooting: Other error codes
The cause of the error must be found and rectified by a specialist. In
the meantime, emergency operation may be maintained. Emergency
operation can be permitted via [→ Main menu → Error → Emer-
gency], see
Chap. 8.1 . If emergency operation has not been permit-
ted, it can be started from the current error screen.
INFORMATION
To ensure that the error has not been caused by incorrect
settings, set all the parameters back to the factory settings
before possible replacement of components (see
Chap. 4.5.9 ).
If it is not possible to determine the cause of the fault,
please consult a service technician.
Please have the essential device data ready for this:
Type and manufacturer number of the Daikin Altherma
ETS(X/H) (see heat pump nameplate) as well as the soft-
ware versions of:
a: Control panel RoCon+ B1 [→ Main menu → Information
→ Values → Software no. B1/U1]
b: PCB RoCon BM2C [→ Main menu → Information
→ Values → Software no. controller]
On optional RoCon system components:
EHS157034 [Software no. B1/U1]
EHS157068 [Mixer software number]
8.1 Emergency operation
[→ Main menu → Error → Emergency]
If the heat pump fails, the backup heater or another external heat
generator can be used as an emergency heater. If [Emergency] is
set to "Yes", emergency operation is automatically activated in the
event of an error. Otherwise, emergency operation can only be star-
ted in the event of an error via the error screen.
If emergency operation is started via the error screen, the [Emer-
gency] parameter remains set to "Yes", i.e. emergency operation is
also started automatically in the event of future errors. If this is not
desired, the [Emergency] parameter must be reset to "No" after the
error has been corrected.
8.2 Manual Operation
[→ Main menu → Error → Manual operation]
In manual operation, the heat pump is controlled to a fixed feed tem-
perature. Manual operation should only be used for diagnostic pur-
poses. Manual operation is started by setting the [Manual operation
status] parameter to "Active". The desired feed temperature is set by
[Temperature, manual operation] parameter.
With hydraulically controlled priority operation for domestic hot water
preparation, it must be ensured that the feed target temperature set
in manual operation is sufficient to achieve the stored hot water tar-
get temperature ([Hot water temperature target 1] parameter).
8.3 Error protocol
[→ Main menu → Error → Protocol]
The error protocol can be read in this menu. The most recent error
message comes first. All previous messages are moved backwards
with each new entry in the position. The 16th error message is de-
leted if a new error message arrives. The error protocol can only be
deleted by Service.
The protocol lists
▪ the error code,
▪ the PCB associated with the error (A1P or BM2, see Daikin
Altherma ETS(X/H) Installation and maintenance instructions)
▪ Date and time when the error occurred.
8.4 Error screen
[→ Main menu → Error → Screen]
Fig. 8-1 Error screen
If an error occurs, the error screen is displayed. This displays the er-
ror code, an explanatory text and the date and time when the error
occurred. Depending on the type of error, a reset can be carried out
in the error screen by selecting the corresponding icons and/or
emergency operation can be started (see
Chap. 8.1 ). Selecting the
Back icon closes the error screen and the display returns to the start
screen.
If an error has occurred, the error screen can be called up manually
via [→ Main menu → Error → Screen].
