Very few brands of converters have temperature compensation. Only one but it costs you lots (Parallax Paramode) Some inverter/chargers have temp comp for the charger and also some solar charge controllers have it.
IMO Randy meant that the Float stage, which may have too low a voltage for when it is cold out to keep the batts from stratifying, does have that shot of higher voltage every so often to stir them. So that sort of makes up for the lack of temp comp on the cold side. 13.2 is good for 80F so is too high for 100F.
So if your ambient is hot like 100F, and you really need temp comp for your Float you can also get a special little charger just for that job (or use the solar if you have it) and use it instead of the converter for that role
