<br>
<br><font size=2 face="sans-serif">There is a bug in V3.63 that defaults
zone heating minimum flow ratio to 1.00 (technically, I think it defaults
to the system minimum overall supply ratio), rather than the system heating
minimum flow ratio (which defaults to 0.01). This will cause systems
with variable heating air flow to use a lot more fan and heating energy
than expected.</font>
<br>
<br><font size=2 face="sans-serif">You can either change all of your zone
flows manually or set a user-defined default code snippet: for the zone
heating minimum air flow (or insert this bit of code in your .inp file).</font>
<br>
<br><font size=2 face="sans-serif">if (#P("HMIN-CFM-RATIO") ==
unused)</font>
<br><font size=2 face="sans-serif"> then unused</font>
<br><font size=2 face="sans-serif"> else if (#RV(#P("HMIN-CFM-RATIO"))
== 0)</font>
<br><font size=2 face="sans-serif"> then
#P("HMIN-CFM-RATIO")</font>
<br><font size=2 face="sans-serif"> else
no_default</font>
<br><font size=2 face="sans-serif"> endif</font>
<br><font size=2 face="sans-serif"> endif</font>
<br>
<br>
<br><font size=2 face="sans-serif">Hope this helps,</font>

<br><font size=2 face="Calibri">Has anyone ran any of their old files in
the new equest yet. My numbers have significantly changed. I
am working on ECMs and my constant volume alternative is saving more money
than my vav alternative. Is anyone else having any problems with
this. Should I not be running 3.61 file on 3.63?</font>
