First question, what is the primary reason you are changing from EasyTouch to Intellitouch? Do you need more relays? And the thread title implies Pentair is paying for the upgrade, is that true?
As far as Remote vs ScreenLogic2:
Remote Pros: cheaper price, easy to use
Remote Cons: only works within 150 feet, only 4 functions
ScreenLogic2 Pros: can set functions anytime and from anywhere, many different functions, integrates great with lights, track and monitor pool chemistry
ScreenLogic2 Cons: higher price than remote, slightly less 'simple'
