Hi all! Does anybody know where to look for electromagnetically controlled heads for radiator valves. I'm playing with an idea to build heating controll using Dallas 1620 in every room to monitor temperature and PIC to control them. So far I was unable to find anything on the net regarding those heads probably because I don't know the propper expression in english for it -) ).
