Heaters incremented.

I talked with Jeff and Travis and we decided to increment heat as we are running out of range in the FMCS controls. Outdoor temps have fallen to ~18F overnight.

In the LVEA - incremented HC1B from 9 to 10 ma (control signal) at 8:16 PST

EX - incremented HC3 from 10-11 ma at 8:18

EY - incremented HC3 from 10-11 ma at 8:19.

 

Edit - incremented EX HC3 from 11- 12ma at 8:33 for some additional heat as response was not sufficient.
