9 Troubleshooting
This section contains all possible error
codes together with the appropriate
solutions that the USER MAY carry out to
restore the boiler to operation — corrective
measures. Other error codes MUST be
dealt with by a quali
fi
ed technician.
The external sensor is placed on the
coldest wall of the property (most often the
northern wall). When displaying an error
code a telephone icon and the letter F
will
fl
ash on the display together with the
relevant error code.
During the normal course of operation
of the device the ten most recent
error alarms can be displayed by
simultaneously pressing for seven
seconds both keys for setting the CH
temperature.
