Subject: HTEMP variation is too much 
The C1:PSL-MOPA_HTEMP variation is more than 0.5 C daily
Normally this temp stays well within 0.1 C
This 80 days plots shows that we have just entered this unstable region some days ago.
The control room temp set unchanged at 70 F, actual temp at ac-mon 69-70 with occasional peaks at 74 F
 
Water temp at chiller repeatedly around 20.6 C at 8 am
This should be rock solid at 20.00C +- 0.02C
