End Station VEA Temperatures Varying
So far we have:
- EY temperature is varying +/- 1.4 °F (from its average of ~65 °F).
- EX temperature is varying +/- 1.5 °F (from its average of ~65 °F).
Attached plot shows last 7-days. Today there were some FMCS issues which came up (noted in Patrick's alog).
I left a voicemail on Bubba's cell phone.

The air handler controller modules at both end stations required rebooting this afternoon which in turn briefly disabled the air handlers. This likely caused the temperature of the VEAs to vary considerably along with the outside temperature dropping from unseasonably warm daytime temperatures. I have been monitoring the FMCS and the temperature in the VEAs appears to be stabilizing. I will continue to monitor.
Temperatures have stabilized at the end stations (see attached).

Nice catch, team!! Tagging OpsInfo & FMP for the thank you. Tagging @DetChar in case it turns out to be important later.
