the upper alarm is triggered when the temperature is 10.0 °C or above for an accumulative time of 10

Once an alarm has triggered, the alarm indicator ( ) remains shown until the unit is reconfigured. The day
alarm marker
remains shown until midnight, then it turns off and the marker for the previous day is shown
(
) to indicate the alarm was registered against what is now the previous day. When midnight passes next,
this marker will move to and so on.
Alarm Re-triggering
A note on alarm re-triggering:
As soon as an alarm is triggered, the corresponding delay time (but not
any others) resets to zero and alarm processing starts again. The alarm processing for all other alarm
delays is not affected. Therefore, accumulative or consecutive alarms will re-trigger, if the alarm
conditions are met again, and the Alarm Indicator ( ) and the Day Alarm Marker (
) will be shown,
even if any previous alarm was cleared. Clearing an Alarm does not reset any of the delay values.
