Tristar 45 PWM Custom Profile
First..... I have a few images in this to help illustrate. Views best if you are allowing images! I tried to repeat in text what the image was saying, but a picture, as we know, is worth more. ...

Almot, I totally forgot to multiple the t compensation. Great catch.
Actually, I wasn't sure that it had to be multiplied - sorry for not making it clear enough. See, controller can detect the battery voltage, i.e. it will "know" the number of cells. Hence, leaving it up to user to do the multiplication job would not be very professional when a hardware chip could do this. In my controller it does this. I only set the per-cell value. In yours - I don't know. Time to read the manual, I guess - this time more thoroughly :)
It's not that "Tristar prefers Celsius" - it's that the batteries and all the theory was developed by European scientists hundred years ago. That's why a round 0.005 number for Celsius, and cumbersome numbers for Fahrenheit.
Separate settings for Bulk and Absorb looks odd and unnecessarily complicated. I used to think of the Absorb stage as of a "prolongated Bulk", i.e. you set either Bulk or Absorb, call it what you want, and controller will go into Absorb when voltage gets there. And will stay in Abs for as long as it finds necessary, as per its firmware and user settings.
