I found the information in my e-mail and sent you a private message asking for your private e-mail address. I'm not sure Weller wants me posting their PDF on-line or not so I'd rather share privately. The PDF is poorly written. I think maybe the person who wrote it might of had trouble with the English language. However, I've sent a few e-mails to Weller and some other people, who were able to help me figure out exactly how to talk to the preheater. You're more than likely going to have trouble talking to it as well, just by following the information in the PDF. If you do though, I'll be more than happy to help you through it. I suggest you download a terminal program and communicate via serial from the terminal program to test the commands you send, until you got it all figured out. It helped me a lot!
Eventually, when I get some free time, I wanted to write an open source program for Linux and Windows that controlled the PDF. I was going to use the GTK 2 libraries to do this and a library called libserialport. Libserialport is still very new (it's used by the Sigrok project) but it allows me to write highly portable serial communication type code for Linux and Windows without having a bunch of #ifdef type pre-processor directives.
Let me know if you didn't get the PM. Thanks!

@Spork,
I too am interested in this protocol information. Would you be able to share?

Hello.
I did a quick setup for weller WHA 3000p. to set the temperature to 222 C, we need to send 6 bytes of data containing - 113, 50, 50, 50, 48, x
x is calculated by the formula x = (113 + 50 + 50 + 50) mod 208
