Hi Mike,<br><br>It will be hard to help you without seeing your .pd2 and .inp files. You could look around in the .bdl file that was generated to see what you see, search on error. That will at least show you the area where the error is occuring.<br>
<br>Good luck,<br><br>Carol<br><br><div class="gmail_quote">On Tue, Nov 2, 2010 at 7:09 AM, Smith, Michael <span dir="ltr"><<a href="mailto:michael.smith@wspfk.com">michael.smith@wspfk.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

<p class="MsoNormal"><span style="font-size: 10pt;">Good morning everyone,</span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">I am curious if anyone has
come across this error or may be able to offer some advice. Until recently, my
simulation was running without any errors or warnings, however, today I am
receiving an error that my chilled water supply off of my secondary CHW loop is
88F. </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>
<p class="MsoNormal"><span style="font-size: 10pt;">In reality, my design CHW temperature
is 40.0F with a 12F DT. The reason I am confused is because my cooling setpoint
control is fixed. I don’t have a reset temperature or water side
economizer. I have looked through the input file for where the temperature
could be coming from, but I cannot figure out where or why the supply would be
forced to be so high. Before I post my files, I was just curious if anyone has
seen the error before. I appreciate any help and comments.</span></p>
