The file locks up. Before I attempted to add this, the building was compiling just fine, but I had attempted to run the baseline and it had given me an error that the cooling coil leaving temperature needed to be 6 F higher than entering water temp. I had tried lowering the entering chw temp, but it still wasn’t converging. So I was attempting to add energy recovery (which the system will have, though I was trying not to add it in the baseline to simulate App G baseline). The system is high percent outdoor air (0.81). Does anyone have any ideas as to what might be causing the file to lock when trying to add the ER? Thanks.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Maria<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span style='font-family:"Garamond","serif"'>Maria T.
