Hi All - new to the forum. I've been watching this thread as I just got all my 15 year old equipment replaced with new pentair stuff: VS-3050, Easytouch 4, ITC40, Mastertemp 400. The part I thought this forum might like to know is that I got lucky and got a "new" easy touch 4, as far as I can tell from the description in this thread. It has both transformers in the high voltage section and a single rail for the breakers on the left. I live in the SF Bay area and got the equipment installed 2 days ago. So at least in NorCal, the new stuff is in the channel.
I ran cable out to the pad, so as soon as I hear that someone has made the iPhone work with the easy touch 4, I'll go buy and install the protocol adapter.
