5.2. Alarm signals

If an alarm arises the circuit starts up the following:
the display shows the related alarm code. Specifically the controller displays the alarm code and the temperature normally
displayed alternatively;
the alarm LED is lit;
the alarm relay is activated.
For some alarms and alerts the led and/or the relay are not activated. By pressing any button the relay turns off (if activated) and
the led flashes, while the alarm code remains displayed. The led turns off and the alarm code disappears only when the problem
is resolved. Table 7 explains each alarm and related actions to be undertaken.
