Hi,
You generally don't need equipment adjustments with BIAB since you are heating the mash water in the pot itself. So if you uncheck the box to adjust for equipment the setting is not needed.
However in cases where you might heat the water in a separate liquor tun (such as a conventional three vessel system) this setting can be used to help adjust for the heating needed to raise the mash tun temp up (equipment adjustment).
