Critical Air Handler Alarm
Critical Alarm at 11:15 for H0:FMC-CS_LVEA_REHEAT_2B_DEGF. Attached trend show past 24 hours for this channel. I'm not entirely sure how long this alarm has been present. Also attached is a screenshot of the current CS FMCS. I noticed the aLog regarding the temp increase at Y end . I have not yet found one regarding the corner station.

Thanks Ed,
Bubba and I are aware of these alarms and are working on the issue. These should probably not be flagged as "critical" as they are duct heater temperatures and a temperature of 100F is not unusual for these.
Our reduced fan flow rates are contributing to the increased temperatures in the ducts.
