Sorry you are having to deal with that. It seems like most pool builders get comfortable with a setup and just want to stick with that for the next 20 years even if there is new technology available. The notable exception is when they get incentives for things like Ozone, UV, minerals, etc. as you unfortunately know.
On the bright side, your PB has been very impressive in their responses so far. Most will come up with some off the wall excuse or just tell people it is too late to change.
For what its worth, IMO if the PB does not change this automation out, you can still get very similar functionality with the Easy Touch + Screen Logic. Its not as shiny and new like the Intellicenter, but not the end of the world and not as important as your other upgrades you did on the SWCG.
