I asked about it too... It's available on the 3ph version but not the 1ph one as there's way too much electrikery involved and the cost is way over what it's worth...
I would also like to see the 252 with Performance, I will ask again when I visit in December.
It does actually show the Performance front panel as an option on the website, but it is a mistake, as its only available in Basic Plus and Control Pro, I have asked them to make the neccesary changes to the website
