<DIV>Gordon, go to the SS-F reports for each zone in your DOE2 output, here you
will be able to identify which zones suffer from underconditioning and whether
it is heating or cooling energy that is insufficient. If it is heating
energy (i.e. underheated) which is my guess for your model then you can adjust
items to offer more heating energy. You might want to install baseboards
in your system & zones, you may need to adjust your reheat coil delta T, or
something else.</DIV>
<DIV> </DIV>
<DIV>You can always send us your .pd2 & .inp files so that we can open up
your project, review it and give you some suggestions.</DIV>

also adjusted my "Heat Temp Schedule" to turn all but one zone to default to
