<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>OK. Thanks. But, I’m still confused.
Below is the input screen for the Chilled Water Loop. By your statement this “Chilled
Water Loop” is, in the DOE manual and conventional practice terminology, the
secondary loop, but why then is the loop subtype “Primary”. I’ve
also pasted in the DOE definitions below. I understand the meaning of the loop
terms, but what I guess I don’t understand is the purpose of the input field
“Loop Subtype”.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Also, if the Wizard does this correctly
and automatically, why do 2 of 4 responses by users to this thread say they can’t
do a primary-secondary from the Wizard alone, but have to go to detailed view? I
guess I’m a little frustrated when I can’t seem to get to the bottom
of things. Thanks for your help.<o:p></o:p></span></font></p>

tree from the detailed set up I did in the second image below. The problem with
that one is I can’t get the one coil load to get off the primary loop and
