ALARM SIGNALS
When an alarm is activated, the display shows the corresponding message that flashes alternating with the
temperature.
• If fitted and enabled, the buzzer and the alarm relay are also activated. All the alarms have automatic reset
(that is, they stop when the causes are no longer present), except for alarm ‘CHt’ which has manual reset
(instrument on/off using the UP button or by disconnecting the power supply).
• Pressing the SET button mutes the buzzer, while the code displayed, and the alarm relay only go off when
