ALARM SIGNALS

In the event of an alarm, the card normally activates the following:
•
the relevant alarm code is shown on the display. In particular, the control alternates the
alarm code and the temperature that is normally shown on the display; if there is more than
one alarm, they are displayed in succession, alternated with the temperature
• the alarm LED is switched on
•
the alarm relay is triggered.
For some alarms and signals, the LED and/or relay are not triggered. The table below gives a
detailed description for each alarm and the relevant actions undertaken.
Pressing any button will deactivate the relay (if triggered) and the LED will blink, while the alarm code
will remain on the display. The LED will switch off and the alarm code will disappear only when the
cause behind it has ceased. The alarm codes are listed in the table below:
