Vision I & II

Can you point to where I can find I&O documentation for Vision I & II? (I need this to evaluate the product before attending a class, should that seem be worthwhile.)

    Vision info

    Bill, If you go to the Heat Transfer website, you will find everything you need regarding Vision I & II

    more detail needed

    Bruce, I see the Vision glossies on the HTP website but not detailed I&O manuals (or equiv). Do you have a URL?

    My solar/boiler retrofit entails plenty of tackiness. I really need to see the definition of all the 'knobs' on that control. Eg, how will it handle a HX interposed between boiler and heating load (issues are servo stability and condensing performance); does it seem that the mixing valve drives can be coupled to existing valves; can the modulating zone controls be made to work with another heat source (solar storage)?
