Thanks for

pointing out this article. It's very timely since I was trying to relate to my hydronics class why constant circulation was a desireable thing to design into a system. Sometimes I have to learn to modulate the amount of information I inject into their brains. Hows that for an analogy? Heewack! :)WW

Nice module

Dan. I just recently learned that 3 way is available in sweat connections with unions. Make for quick, easy replacement. Take the other back to the shop to clean and rebuild.

A certain beauty in simplicity. Years ago, probably 10 or more, I used a few tekmar pulse width modulation controls. You merely pulsed a basic on/ off zone valve to mix high temperature into the radiant zone.

Makes you wonder why we have gotten so complicated, and expensive with mixing controls. How accurate is accurate enough
