Note that the Iota charge controller is not the same as a PD's Charge Wizard at all. The Iota one does not let you force it into 14.x by pushing a button.
All it does is turn their basic single stage converter into a three stage converter, with its own sort of charging profile--see their website on that.
BTW a single "stage" (voltage) charger does two "stages" on the battery-Bulk and Absorption. So, eg I just set my single stage charger to 14.8v and let her rip. When the battery is full at 14.8 I can yank that charger and swap to a single stage 13.7 Float charger or else dial down the 14.8 to 13.7 on the first one.
Terminology matters :)
