I am installing a hydronic driveway snow melt system. I would like to monitor the performance of this system via a number of themocouples embeded in the return lines, supply line, heat exchanger in and out etc. I think eight should do it nicely. i would like to read these values (temps) on a PC at some other location ( but still on wired network). I would think there must be a simple input box that can output a rs 232 signal or usb etc. Anybody have any ideas.
