Thanks for the quick answer!
Now, can I find the 1132b in 220v version in the USA? The 20amp/220v appilence for the boiler is available here

But I could not find the right contoller...
Connecting it to the Internet is just a programming issue. If I'll know how to make a program that turns on the boiler (with the controller), I can, for example, make a program which reads an email and turns it on when an email arrives. Then I'll be able to turn on the boiler with my mobile phone... Of course there are many security issues here, but as I said, it's a programming issue.
Thanks again Saar
