Go to www.taco-hvac.com and search for the Radiant Made Easy Application Guide. Comes in a bunch of chapters as PDFs.

Also see their I-SeriesR mixing valve with built-in outdoor reset. Might be just what you need.

You could also check out www.tekmarcontrols.com in the Literature section, some of the technical essays talk about mixing methods and have good diagrams.

Radiant Diagrams

Hydronics engineer John Siegenthaler has written numerous articles containing diagrams of radiant circuits for Plumbers & Mechanics Magazine (www.pmmag.com); he always includes a diagram with his articles.

You would have to go thru a registration process before given access, or you could Google the following titles to access the diagrams:
"Dashed Expectations", "A little floor warming Please", "Less is More", "The do's & don'ts of 3-way thermostatic valves", "Beyond Closely spaced tees", "a signature system".

Once you click onto any of these articles, it will include numerous additional articles you can click onto to get the info you need.

Siegenthaler also has a well-known book carried by most public libraries (read free of charge), "Modern Hydronic Heating" that is an easy read & contains numerous easy to read radiant & hydronic circuit diagrams; there is also a reference section that explains the meaning of each of the diagram symbols he uses.
