G'day, Mate. Here's how I got close to what you're trying to do. I have had a link 2000R and Lifeline AGM's for 16 years aboard my Mason 53. I set the battery
type to lead acid and then set the temperature compensation (I can't remember what function off the top of my head
and I am not on the boat) to manual and pick the temp that matches your parameters. You should be able to get pretty close if I remember.
If your batteries are in the engine
room, you may need to tweek it a bit as your batteries may get pretty warm during charging
(you will need to raise the temperature setting that you manually set).
Trust that will help. All the best. Cheers
