High Alarm.
An alarm can be set to alert the user that the process temperature is too high.
Should the HA be triggered, the system will go to FULL COOL and the display will flash HA.
The temperature alarms are monitored even if the system is in IDLE, in case the user turns
off the system without removing the load. In such an instance, however, the unit is incapable
of supplying full cool, and it is the responsibility of the user to correct the anomaly.
Span High. Defines the maximum allowable setpoint. Adjust the values of Span High
and Span Low to define the range of setpoints acceptable for your particular
application.
Span Low. Defines the minimum setpoint in this range.
Low Alarm. Same as HA, except the system will stop all refrigeration and display LA.
Both HA and LA require user reset; clear the messages by pressing the  key. They
will not disappear even if the process returns to the correct level.
