What purpose does that serve?

If the charging V is over 12.8 the start batt will just sit and not be using charge amps if its full.

The most difficult part of charging is remembering to UN merge the house and start batts.

For me turning the engine key off should be all thats required.
The combiner shares the house charge current with the start battery when selected on. This provides a float charge to the start battery from shore power in the slip. (single bank battery charger)

No need to "unmerge" when charging as the combiner does this automatically when the charge stops. It's all explained in great detail on the Yandina website.
