<p>Patricia,</p>
<p> Once you open the *.dck in TRNEdit, you can just change the
block that reads:</p>
EQUATIONS 2<br>
AColl = 4.0<br>
DHWDailyLoad = 200
<p>to <br>
</p>
CONSTANTS 2<br>
AColl = 4.0<br>
DHWDailyLoad = 200<br>
<p>While the TRNSYS engine and the parametric table part of TRNEdit
make a distinction between CONSTANTS and EQUATIONS the Studio does
not.</p>
<p>The access violation error is (I think) an old bug that has been
fixed. I would recommend you contact your distributor to make sure
that you are using the latest version. <br>
</p>
<p>kind regards,</p>
<p> David</p>
