Temperature Out of Range
If the measured Discharge Air temperature transgresses the
user selected high or low alarm thresholds, the Quick View
indicators will change to
ORANGE
.
Temperature Alarm
If the measured Discharge Air temperature transgresses the
user selected high or low alarm thresholds for the appropriate
alarm delay period the
icon illuminates.
Service Required Alarm
The
icon illuminates as an indication that an alarm
condition exists not related to case temperature such as a
faulty sensor, loss of peer – peer communication, disconnected
EEPR or EEV, etc.
