[EnergyPlus_Support] HVACTemplate:System:PackagedVAV

I am trying to model a Packaged VAV system, and I am using the HVACTemplate:System:PackagedVAV object to do so.  I am getting the following warning when the object is expanded:


** Warning ** Output:PreprocessorMessage="ExpandObjects" has the following Warning conditions:
   **   ~~~   ** Warning:  In HVACTemplate:System:PackagedVAV "RTU Packaged VAV" the Heating
   **   ~~~   ** Coil Design Setpoint is greater than the Cooling Coil Design Setpoint. This
   **   ~~~   ** may cause the heating coil and cooling coil to operate simultaneously.
   **   ~~~   ** Check results carefully and adjust controls if needed.


The warning is telling me that I should have my cooling-coil temperature (currently 55*F) warmer that the heating-coil temperature (currently 75*F) so that they don't fight each other.  This would be fine if I had a a main heating coil & and reheat coil, but in this case the main heating coil needs to provide all of the heating.  

Has anyone run into this issue before?  Or, has anyone successfully modeled a packaged VAV system without reheat coils?  If so, how do you keep the heating coil and cooling coil from fighting each other?
