I'm in the process of building a new pool. Gunite was shot Monday 5/3. The pool was originally bid with the Jandy PDA6 controller. In final negotiations, I got them to agree to make the system operable from off site using an iphone or mobile device. Now the final contract includes installing an upgrade kit to the PDA6 to make it iphone functional. My question is, why not install one of the "new installation" kits that includes this function since the pool is new instead of "tacking on" as you would do with an existing pool? I asked the PB to look into this but haven't heard anything back. Is it cheaper for them to go the "upgrade" route or do you think they just didn't realize there was a new install kit that included everything? I think it's an honest oversight because the PB admittedly has not done an iphone capable system before. Anyway, I'm just looking for some input because I'm new at all of this and just wanting to get it right the first time. Thanks for your input!
