EY Chiller 1 In Latched Alarm
I received a text Sunday morning about moderately rising temps at EY. When logging into the FMCS, Chiller 1 was in a latched alarm. I enabled chiller 2 to run, as well as the chilled water pump 2. The two pumps ran in parallel for approximately 15 minutes before I commanded chilled water pump 1 off.

The latched alarm is once again an "Evaporator Flow Lost" likely from last week's work to fix the damaged wires/flow switch. No temperature excursions should be expected at that building. Work to remedy the latest issue will begin Thursday 10/19
