I adjust SLOWDC to see what value to lock each cavity.
For ACAV I adjust SLOWDC so that VCOMON fluctuates around 0 and record the value of SLOWDC
I adjust ACAV_SETPT to see how the DC changes (in RED), it seems I have to reduce the ACAV_SETPT
SLOWDC -0.1118 ->-0.1151 -0.1051
SETPT 37.3 -> 37.35 35
Now, ACAV_SETPT is changed to 37.15, but ACAV_TEMPAVG goes up (after 30mins.) to ~37.43 (from 37.3).
The variance from ACAV's 4 temp sensors are getting larger.
