EX Chilled Water Temp
I received an EPICS alarm at 6:27a regarding chilled water supply at EX. I arrived at the end station roughly 10 minutes after. I found the CHWP 2 running normally with normal supply line pressure. The temperature of the water was elevated at roughly 60F and most notably, Chiller 2 was in a run inhibit state stemming from a low refrigerant temp alarm. I reset the alarm, the inhibit condition lifted and the chiller started. It ran normally for about 15 minutes before I left. The chilled water is now back to set point. There is a small incursion to the EX space temp (roughly .4 F) and has since fallen back to its norm.
