The temperature alarm function activates if the temperature of the freezer compartment is higher than -12 °C,
therefore:
The temperature alarm led switches on ( where needed ! );
The compressor is switched on by the electronic board;
The buzzer sounds intermittently with short tones ( where needed ! ).
The alarm function stops with the reset of the compartment temperature, therefore:
The temperature alarm led switches off;
The compressor functions again in thermostatic conditions.
The electronic board features a reed-element which detects the presence or absence of the magnet placed on
the door.
The door open alarm activates if the door of the appliance remains open more than 90 seconds, therefore:
The buzzer sounds intermittently with long tones.
The alarm function stops with the door closure or with the pressing of the SUPER button.
The defrosting heater alarm function activates if at the beginning of the defrosting procedure the electronic board
detects the lack of the defrosting heater (it may cause a breakage or the detachment of the connector or a short
