Sorry is was not clear what i was talking about is that there is menu on the controller screen where you can change some setting and they look similar to mine. i have those menu but dont know what setting will do exactly what.
This is a test unit and in the future i would like to heat come floor with this machine not just hot water.
My boss also have 4000 sq. feet to heat and have alredy hydronic installed in part of the house so maybe i will do the project with him at his house and he can invest in the tools neede for this!
he pay alot of hydro now with our very cold winters. is last geothermal setop cost him 80 000$ so he is very interested in the diy information i found here and is willing to test lost of things at his house like horizontal loop and pond pump and dump if he finally buy the next door lot with the pond!
so what i dont know yet is what is the common temp for hydronic loop?
also thank you for all you input
