Increased CP4 LLCV from 34% to 36% open. Auto fill did not complete - timed out after 60 min. I did a manual fill from control room @ 1:11pm local at 70% open. Took an additional 6 min. (+ 60 min from autofill).
Increased CP3 LLCV from 15% to 17% open.
Note that CP3 exhaust line is more insulated with snow/ice than CP4.
