The ps-8 should do what you want, I'd call Goldline and be sure that it will do the specific things you want it to do without having to have one of their 'traveling techs' come out and add a $ extra part to the system. Also, get the poolside remote, not the inside one. If you've any more ?s, please feel free to ask.
HTH, welcome to the forum! I've played with the cams, I had to to get improperly (for the purpose) plumbed pools to do what they should with the press of a button (ours actually require the press of 2 buttons to do what one should ), but it cuts down on the 'usefulness' of our pools - we had to sacrifice control of all of the 3 suction ports to allow for the spa . As I said earlier, it's because we didn't know about the upgrade when the pools were plumbed, which s*cks for us and the customer. Glad you found the forum and hope you use it to keep a crystal clear and trouble free pool and, of course, if anything ever goes wrong.
