Typically, -3mV per cell per degC, so -1.67mV per degF. For a 6 cell string, then -10 mV/degF. Don't forget the minus sign.
I've seen some batts where that 3mV is 4 or even 5, so a bit mushy. I use ~4, over 24 cells, so a round -100mV with flooded batts.
So take your choice, but I think what you have now is too high. You could also reduce your Absorb setpoint a little if you want, as some batt makers give a range, as they assume most users don't have temp comp. And then don't tell you why there's a range..
Look to your Temperature Compensation. It seems quite cold there, so the set V's will rise.
Also, your TC setting is very high (chopped in your screenshot), much higher than I'm prepared to use. Where did you get that from?
If your temp reading is properly networked, an adjustment there should be pretty much real-time, else you may have to wait for tomorrow's startup.
Just quickly scanning, I notice recommended amperage is 30A or less, and you’re set for 50A. I’m not sure if that can cause an over voltage situation, though.
