<DIV><FONT size=2 face=Arial>1. Go to Fans/Flow Parameters/Set 'Min Flow Ratio'
to 1. This will make sure that the air volume does not vary.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>2. Go the the Heating tab under Coil Cap /
Control, set the Zone Heat Source to 'Not Installed' then right
click on Reheat Delta T and select Restore Default. That'll make the Reheat
Delta T option grayed out. Now specify the Hot Deck Max Leaving Temp-- can
be the same as Zone Entering Max. Supply Temp., it is the maximum
temperature of air leaving the heating coils.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>3. The other option would be to change the system
type to Reheat Fan System and don't specify any reheat-as per 2
above.</FONT></DIV>

<DIV class=Section1>
<P class=MsoNormal>All:<o:p></o:p></P>
<P class=MsoNormal>I am attempting to change my VAV system w/ reheat to a CAV
system w/ no reheat. I believe I have accomplished the change to constant
volume by changing the 'fan control' of the AHU to 'constant volume'.
<U>How do I remove any reheating from the previous VAV system?</U> Do I
change the reheat delta T to zero?<U><o:p></o:p></U></P>
