BRSX Trouble shooting

Some initial trends for those offsite.

Temps at both end stations have been climbing (see aux channels) and both BRS drifts are approaching their 'red' lines.  Notice, X drift has crossed the line and this will be our focus for recovery.

Haven't looked at other temps yet but suspect the sudden cold snap HVAC response.

disabled damping but can't say that is improving the situation.  Attached is 2 hour trends.  The on-BRS temp sensor is increasing but the magnitude is small.
