Confirmed with a trend that the ambient temperatures have pushed the EX chiller into and past the low alarm levels.

The Major/Low alarm at 23:42UTC had a temperature of 34.99F.

The channel went back in the NO_ALARM state at 23:47UTC with a temperature reading of 35.45F.

I followed the alarm handler guidance and made a 10 day trend which shows that this has been happening for a while, so no notification/action needed.
