One reference says that the PL-PLUS will do 4 valves, but another says 3 valves.

If you're sure that you only need to control 3 valves, then it should work.

If you need to control 4 valve actuators, check with Hayward to be sure.

What VSP do you have and how old is it?

Some VSPs don't work with automation.
