SECOND: go to the DOE-2 reports and find the "auto-sized" calculated gpm value for the system loop. THIRD: use this gpm value to now calculate the kW/gpm value that you have to use and then you will have your kW value that you are supposed to input into the kW input for the pumps. You <u>do not need to</u> input the "auto-sized" gpm into the gpm input window. This input remains blank all the time in the baseline.<div><br></div><div>This should clear your errors. When you specify too many input parameters then DOE-2 will start to use those inputs 'against' each other, thus causing the warnings you are seeing.</div><div><br><div apple-content-edited="true">
