<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>
<P>might have insufficient heating capability.</P>
<P>Check that the SYSTEM or ZONE HEATING-CAPACITY plus this</P>
<P>ZONEs BASEBOARD-RATING is adequate to maintain the ZONE</P>
<P>specified DESIGN-HEAT-T for the calculated peak ZONE load</P>
<P>(see LS-A or LS-B for the ZONE peak load.)</P>
<P>SYSTEM AHU-1 </P>
<P>which supplies the above listed ZONE, has a design heating</P>
<P>coil exit temperature, HEAT-SET-T,(plus any zone reheat)</P>
<P>below its MAX-SUPPLY-T or the ZONE DESIGN-HEAT-T, which</P>
<P>might account for the insufficient heating capability.</P>
