I created my model in v 3.63 (due to excessive 3.64 crashes), and have had some problems getting the model to simulate. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>An error that keeps reoccurring states that the zone where the refrigeration is located must be the first zone defined in its system ie Zone 1 must be the first defined zone in AHU-1. However, even after I fix this, the error keeps reoccurring. Saving and re-opening the model has not helped. I’ve noticed that moving the refrigeration to the zone that is defined last within the system sometimes fixes this, but not for all systems.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Anyone have any experience with this?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:#F79646'>Kristin Gustafson</span></b><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:#F79646'> </span><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'>Energy Analyst</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'> </span><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p></o:p></span></p><p class=MsoNormal><b><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'>EYP Energy</span></b><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'>College of Nanoscale Science & Engineering</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#7F7F7F'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'>NanoFab East, Suite 1400 </span><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#F79646'>/</span><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'> 257 Fuller Rd </span><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#F79646'>/</span><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'> Albany </span><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#F79646'>/</span><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'> NY 12203</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'>T 518 438 1393 </span><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#F79646'>/</span><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'> C 518 527 3673 </span><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#F79646'>/</span><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'> <a href="http://www.eypae.com"><span style='color:#7F7F7F'>eypae.com</span></a></span><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#7F7F7F'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'> </span><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#7F7F7F'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#F79646'>/</span><span style='font-size:8.0pt;font-family:"Arial","sans-serif";color:#7F7F7F'> 2010 Best Firm to Work For</span><o:p></o:p></p></div></body></html>
