In the event of the +$ or +) alarm signal, the signals can be reset,
both the signals and the recording of the status can be cancelled completely:
• press the button for 2 seconds to turn off LED ì , silence the buzzer and deactivate the alarm relay, if present. The display
still shows the +$ or +) alarm status (segments  and ú in the figure) and the alarm code;
• use the parameter WR to completely cancel the pending alarms, signals and status recording variables.
Warning: resetting the signals or the entire status of alarm cancels the signals requested by the HACCP module; if other alarms
detected by the plug-in instrument are present, some signals may remain active.
