Right, but the input voltage at which it exits the boost or trim mode
might be slightly different than where it enters that mode.

It's like your thermostat - there is usually some hysteresis around
the temperature set point.

On the other hand, some UPSes may just implement a time filter that
checks to see if the voltage has been past the set point for a certain
amount of time.

As Peter mentioned, it would be good to get clarification from Arnaud
as to whether the separate settings are all necessary.
