    Mod Con Manual

    Tim, do you plan on copying the manual to CD?  What about including the Viessmann Vitodens 100 and 200 models?

    A CD is a future possibility

    but not right now.

    As for Viessmann I have attempted to get information from them with no success. I attended their school here locally and found the facility impressive but the material made available was geared toward product and not set up as a training program that could be converted to text such as I am working on.

    It is very difficult to get information from many of these companies as they feel there manuals are all people need and will not release information on problems or solutions except on a need to know basis. 

    To coin a phrase it is like "pulling teeth"

    Dealing with Viessmann

    Have you tried dealing with Rich Corcoran, in the RI office?  Or Harald Prell in the Waterloo headquarters?  I'd be very interested in seeing if they would help. 

    I've had issues with incomplete technical troubleshooting in their existing service manuals, which drives me, and the techs crazy. I've had the same issues with other mod-con boiler manufacturers, and would like to see more comprehensive (and specific) diagnostics.

    Please post bibliographic information

    Thank you, Tim, for posting about this book.  YOUR book?  I wish you every success.

    I come from a background in libraries, so I may be prejudiced, unfairly. 

    BUT, I trust that you can sell a fair amount of books into public libraries, which is a large market.

    HOW to go about it is a longer topic (e.g. distributors and wholesalers...) but I want to encourage you to do two simple things now, which will help both you and the rest of us:

    1.  Tell us the basic bibliographic information about the book (in each

    case, as it appears on the title page).  Any prospective buyer can then

    refer to it accurately, e.g. when asking for its review or purchase.

    Author's name


    Place of publication


    Date of publication

    You remember this from some high school or college class, no doubt, and

    perhaps without fondness.  ;-)

    2. Send a copy to the Library of Congress (LC).  (I am sure the necessary info is on their web site.  The last time I did it, it was all paper-based -- that long ago).

    This has 3 benefits:

    a. You will explicitly obtain copyright.  (It is declared by your printed statement of copyright in the book, which IS sufficient.  But you can get belt and suspenders copyright protection by applying to LC.)

    b. They will enter a record of yuor book in their searchable database, which libraries around the world use.  Meaning: Joe Blow in Needs Heat, MN, can ask his library to consider buying a copy, and the library can look at LC records to see that it even exists.  Then they follow their decision-making and purchasing channels.

    c. You will also be able to -- maybe you already have -- ask LC for Cataloging-in-Publication data.  (Which the publisher typically places on the back side of the title page.)  This promotes sales, because the work of cataloging has been DONE -- you have greased the skids for library sales.  (When I was young the rule of thumb was $10/title for original cataloging.  With inflation, I assume it would be something like $30 now.  Now: when LC catalogs something ONCE, everyone else just uses an electronic copy of their work, with HUGE savings for all.)

    I didn't mean to say so much, and to sound preachy, if I do.  (These are all just a helpful set of conventions, like using a red wire for hot, and black for ground, etc.)  Best wishes!

    what i see lacking in manuals, is a more comprehensive operations explanation.

    timers/ time-outs the machine uses, limits, when limits are reset. fault data tables......

    if you have a good understanding of its operation, you really don;t need diagnostics, which, always tend to be poorly written, and really are hard to write!

    I'd like to see the machine program sequence.

    Yes I have contacted

    Rich and have meet with him but to no avail. The information I have requested was not made available. I will try Harold and see how I make out.

    I also contacted Rich Tretheway who once distributed Viessmann but he has destroyed all his material on Viessmann.

    Viessmann Manual


    I believe they have a new tech/service manual at the printers as we speak on the  Vitodens line. I had to call concerning a F4 error code on the new 200.  One of the troubleshooting cheks is to measure ionization current but there is nothing in any of the manuals that tell you how or what readings they are looking for. Fortunately figured out the problem without having to do the test. Tech support also has nothing on it. Was told they were waiting on this new manual.
