Diagnostics And Errors - Immergas CRD Instruction Booklet

8. DIAGNOSTICS AND ERRORS

The Digital Remote Control constantly
controls boiler operation status, signalling
any anomalies by displaying the message
"ERROR" (detail A fig. 12) and the cor-
responding error code. In case of anomaly
with manual reset the display will show the
message "ERROR" alternating with the
message "OK" (detail B fig. 12); press the
button to reset the boiler.

NOTE
Possible error codes displayed may depend
on the boiler model the Digital Remote
Control is connected to.
For information on these codes consult the
boiler instruction handbook.
In case of non-resettable errors call a quali-
fied technician (e.g. Immergas Technical
Assistance Service).
NOTE
In case of block with manual reset, up to 5
consecutive release attempts can be made,
after which, resetting from the CRD is
inhibited. Therefore operate the release
button on the boiler to restore normal
appliance operation.
