The alarm can be reset either automatically by the control
or manually through the touch panel display or the web
interface (in the Reset Alarms menu).

which are currently active on the unit.

restarting. Once the cause of the alarm has been identified
and corrected, it will be displayed in the alarm history.
IMPORTANT: Not all alarms can be reset by the user. Some
alarms are reset automatically when operating conditions
return to normal.
