Alarms
During an alarm condition, the status LED bar of the display will light up in red. The red
box on the main screen will indicate what alarm(s) is occurring. This table helps
troubleshooting what may be causing the alarm.
Each alarm is logged in the History menu. This log is useful because it shows all alarms,
even ones that may have automatically reset. It records the name of the alarm, the date
and time when it occurred and temperature and humidity readings.
