Hi Marco,

We are not doing anything to the system. The sensor might have been hit or came loose during the recent work in the hall, causing the noise. We are free to meet with you guys here in the control room around 11am.

Regards,
Amanda

Dear Amanda,
the chiller is again behaving out of control (increasing the temperature).
Are you doing anything on the system?
we are also having a huge noise on INTLK TEMP2  sensor that sopped for a 
brief while before to start again.
Any guess?
Can we pass by to your office late this mourning  to discuss together 
what could be the caus of the problem?
Thanks in advance
Marco
