Remote logged in and changed the setting for CP3 LLVC due to the amount of time it took to overfill, I did single unit steps, started around 19:41 utc, changed it to 15 from 14, watched it for 10 minutes, but no increase on pressure and temperature remained the same.
A second change at 19:53 utc, to 16 from 15, no noticeable change on temperature, but pressure went up to 0.1 psig.
A third change at 21:04 utc since themocouple temperature was still hovering around -10 oF, setting changed to 17 from 16, pressure went up to 0.3 psig, and temperature started moving, on the course of 4 hours it went down to -19 oF from -10.
I wiill leave it at this setting (17%) and re-evaluate tomorrow, since ambient temperature suppose to go up.
