When we got our new Buderus BG142 with outdoor reset, we also rearranged our heat zones and added heat to about 500 ft2 that previously had none. Now we're running 4 zones (4 stats, 4 pumps) for a variety of space heating styles, and 3 zones (3 stats, 3 valves, 1 pump) of floor radiant. I would like to know how much each zone is running. For example, if 3 zones run 20 minutes/hr, and one zone runs 60 minutes/hr, I could explore adding more emitters to that zone to get more equivalent run times. Run time % would also show how well the outdoor reset heating curve is set up. I can set up a computer to store/display data, for example if the devices were polled each minute to determine state, and that data would be stored, then I could do an Excel graph that would show how much they ran. Way cool. I don't know how to get the data. What widget would attach to the TT for each stat (24V) to show whether it's open/closed? How would that widget connect to the PC, and what software would collate the data? Or poll the pumps at 120V instead of the stats. Even more cool would be tracking the water temps as well. Could you imagine a graph with 7 different horizontal lines to show off/on, overlaid with the supply and return temps? Is this heaven, or what? Even add a boiler status indicator...
