color=#0000ff size=2>How many hours of unmet load do you have for zones served
by these units? See reports SS-F and/or SS-R. I often have these
warnings even when all my zones are conditioning properly. If that is
the case, ignore the warnings and don't waste your time trying to fix
them. The nice thing about SS-F is that it will tell you how cold the
zones are getting and the months unmet load hours occur.</FONT></SPAN></DIV>

color=#0000ff size=2>If you have a lot of unmet load hours, I would start
checking to see if my zone thermostat schedules, heating availability
schedule, and fan schedules match. If the hours of unmet load occur
during the summer, you have simultaneous heating and cooling. Try
setting the heating thermostat to 55 during the summer months to eliminate the
call for heating.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2>This is still my first time creating my
simulation and I thought I was on the right track...</FONT></DIV>
<DIV><FONT face=Arial size=2>I have a 100% OA unit with a preheat coil and
chilled water cooling coils to maintain a 52 deg off the coil. The zones are
</FONT></DIV>
<DIV><FONT face=Arial size=2>handled by singe duct, straight VAV terminal
units with hot water reheat coils. I have set all</FONT></DIV>
<DIV><FONT face=Arial size=2>the zone set points to 72 degrees and I am
getting a message that reads as shown below. I have </FONT></DIV>
<DIV><FONT face=Arial size=2>inputted the heating capacity for the preheat
coil and the capacity for heating in the zonal VAV terminal unit.</FONT></DIV>
<DIV><FONT face=Arial size=2>Just to see what would happen I grossly oversized
the VAV heating capacity to see if the error would be fixed,</FONT></DIV>
<DIV><FONT face=Arial size=2>it did not. I checked the LS-B space peak loads
and it shows that the zone heating capacity required is only 25% of what I am
inputting. Please help, I have no clue what I am doing wrong.</FONT></DIV>
<DIV><FONT face="Courier New" size=1>
<P>**WARNING**********************************************************************</P>
<P>ZONE TU1-6 </P>
