Although it does not say on the description page,when I recieved the book I could immediately tell that it was similar to an older version (which I also had)The old book is called "Automated Home Control" , "Design and Installation & Programming Manual. X-10 and Hardwired I/O Based Systems" 2nd edition by Silent Servant Home Control Inc. 1998The book really covers the X10 controllers Stargate and CommStar, together with other X10 stuff from Leviton, et, all.It shows many wiring diagrams, but not programming.It has good ideas illustrated within it, but I do not find it worth the cost.I would say only for the X10 fan. Others should stay away.Stefan Decuypere
