Well, I called Zodiac and level 1 dude said I needed an authorized tech out here. I pushed back and got his supervisor who said it should work, must be a bad board or a wire is loose. So I went back to the instruction sheet and double checked it to see if I missed something. Nope. Then went to the install manual and rechecked install procedures, nope. However, there was an intro paragraph I must have skimmed which said the cpu memory must be cleared before or after installation, and to "follow the prompts." So I went into the iAqualink web control's system setup and lo and behold was a button for clearing memory. Yup, that fixed it. Too bad Zodiac didn't suggest that. Ultimately my bad, should have read manual twice, open mouth, insert foot! Thanks for the replies. Cheers to all.
