Yup what Brian said.

The Intro does have " Advanced diming proportional control" checked. That’s
the standard of all of our products. We recently added pulse proportional
to the Herpstat 1/2 models but the intro doesn't really need it as the only
real advantage of pulse proportional is avoiding hum with metal racks which
the intro (being a non-grounded anyway) is not marketed for.
