Alarms and warnings are identified by error codes. For the error
code table, see "8 Troubleshooting" [ 4 17].

sequence.
Digital outputs can be configured to signal the warning/alarm status,

To reset an alarm or warning

Both warnings and alarms can be reset automatically, manually, or
semi-automatically (see alarm table):
▪ Automatic: when the cause is no longer present, the alarm also
ceases.
▪ Semi-automatic: reset is automatic three times in an hour, after
which a manual reset is required.
▪ Manual: when the cause is no longer present, the alarm remains
active until manually reset by parameter.
The alarms can be reset manually using parameter rSA , via the
user terminal or configuration tool, or in Daikin User (Bluetooth
connection only) using the specific command on the alarms page
("Service" or "Manufacturer" level access is required).
If the condition that generated the alarm is still present, the alarm
is reactivated after resetting.

Alarm log
When an alarm is cleared, it is stored in the alarm log containing a
maximum of 5 alarms, in a FIFO list (the 6th alarm overwrites the
first alarm, and so on). The error log is accessible via the user
terminal, via supervisor or the Daikin User app (Bluetooth connection
only).

The controller can record both periodic and event logs, which can
then be viewed and downloaded using the Daikin User app and
commissioning tools.
