Doh Ok, thanks for the clarification.
So, that means out of all the people I have spoken too, that have all said that you can't have 2 different temps in two different zones, are statistcally most probably correct.
... and I haven't seen anybody that said said it's possible.
Well, I think I've come to the sad end. My house could have really used a system like that.
Thanks for your help all.
