i have not specified a massflow for the loop so it was up to equest sizing the
massflow. Do you get appropriate massflows ? I tried it with other delta T but
the temperature difference is always too low and the massflow to high. Sizing
option is primary. Any idea? Have a nice weekend.<o:p></o:p></span></font></p>
