ALARM SIGNALLING
If there is an operating anomaly, the stove goes into alarm shutdown
mode and informs the user of the type of problem that has occurred via
a 3-figure code displayed on the rear emergency panel.
The alarm is permanently signalled by the corresponding 3-figure code,
by a flashing red light on the emergency panel, and, for the first ten
minutes of the alarm, by a periodic acoustic signal, which can be
interrupted by turning the unit off with the remote control. To exit
alarm conditions and restore its normal operation, read the instructions
in the next two paragraphs.
The following table summarizes the possible alarms which the stove
may signal and corresponding code which appears on the emergency
panel.
