Set it all up and must say that it works very very well. You can choose to run up to five different control loops (not water loops) and basically all you need to do once initially setup is to figure out the average temperatures for each control loop and then set that up.
So for example down here, my average water temp as per the water probe is 30 degrees and climbs to around 32 degrees at load. So I input 30 degrees as ideal temperature and the associated fan and pump run at around 80% till the temps go above 30, then they start ramping up. You can also choose to run them lower, by changing a few criteria, but I choose to run them at minimum 80%. My second control loop consists of the temp prove at the base of the pump and a single 120 mm fan. Again the fan ramps up based on the temp showing there. The third loop runs on the basis of the temperature of the controller itself. The controller ran at around 40-45 degrees without a fan, but once I setup the loop, with a fan directed at it, the fan starts ramping up over 34 degrees and now it stays at a cool 34-35 degrees.
I just wish I could find a way to connect a small lcd monitor to it, so it could be more useful and I could then disconnect the USB.
The biggest issue I had was the length of the USB cable provided. I finally cut the connectors and extended them all the way to the internal USB port I wanted to use. I think I will get a proerp internal USB connector, instead of four different connectors and rewire it.
