color:#1F497D'>I just did one like yours that worked out fine. The issues I had
to work out to get the model correct had to do with airflow. I originally had
high heating and low cooling loads. The minimum airflow to the zones had to be
set at 100 and the source set to “snap acting”. Obviously the Hot
Deck reset schedule has to be reasonable as well. Is this the only source of
heat in the building?<o:p></o:p></span></p>

<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Hello All,</span>
<o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I am trying
to model building with a Multi-zone air handler that uses a DX coil for cooling
and Hot water coil for heating. After simulating the model the heating
energy is astronomically high while the cooling energy is normal. I have
tried to change inputs and controls to no avail. Does anyone have
experience with this problem? Any ideas on what I should try to look at
first?</span><o:p></o:p></p>
