Types of Alarms
There are three types of alarms. They may occur
individually or along with other alarms. There can
be more than one alarm present at one time.
Alarms that occurred during a Unit Self Check
will be preceded by a dash (-).
Stored Alarm:
Indicates that a condition exists that
does not affect unit operation but that should be
investigated. The Alarm icon will appear for
30 seconds when the unit On/Off switch is turned
On and then disappear.
Check Alarm:
Notice to take corrective action
before an abnormal condition becomes severe.
The Alarm icon will appear and remain On.
Shutdown Alarm:
Indicates conditions that may
damage the unit. The unit will automatically shut
down, the Alarm icon will appear and the entire
display will flash On and Off.
