I have a WaterBoss. If I understood the manual correctly, the hardness
setting merely determines how many gallons of softened water you can use
before it regenerates. AIUI, as long as the thing is not overdue for
regeneration (i.e., as long as you did not tell it that your water is
softer than it really is), the water it supplies will be as soft as the
device is able to make it.

The hardness is one of the 3 parts needed to correctly set up a
softener. The other parts are the salt dose and how much water is used
daily.
