EX Temperature Setting Increased to 67 Deg F

Richard, Betsy, Eric.

 

Looking back many years we can not find a reason for the temperature setting of 65 Deg F at EX.  Today I raised the temperature to 67 Deg F.  Wtih the clean room on we have seen a diurnal swing of 3 Deg F with no effect on the suspension so this rise should not have a negative impact on the suspension.(sagging)  It may actually help.

However,  It will probably change the balance of the BRS.  Jim W is aware
