[EnergyPlus_Support] An error when applied the UCSD Displacement Ventilation Module



Dear all,

I modeled one floor of a building with displacement ventilation builidng. I used the UCSD Displacement ventilation module in my simulaiton model. Then I got the  following warnings and error.

"Warning ** Calculated Relative Humidity out of range (PsyRhFnTdbWPb)
   **   ~~~   **  Occurrence info=CALGARY INT'L AB CAN WYEC2-B-25110 WMO#=718770, 01/02 05:00 - 05:10
   **   ~~~   **  Dry-Bulb= -333.04 Humidity Ratio= 1.000E-005 Calculated Relative Humidity (fraction)= 844.67
   **   ~~~   ** Relative Humidity being reset to 1.0
....

   **   ~~~   **  Occurrence info=CALGARY INT'L AB CAN WYEC2-B-25110 WMO#=718770, 01/02 05:05 - 05:06
   **   ~~~   ** A temperature out of bounds problem can be caused by several things.  The user
   **   ~~~   ** should check the weather environment, the level of internal gains with respect
   **   ~~~   ** to the zone, and the thermal properties of their materials among other things.
   **   ~~~   ** A common cause is a building with no thermal mass -- all materials with
   **   ~~~   ** Regular-R definitions."

But I did not use reguar-r for building materials and construciton. In addition, the model without the UCSD DV module has not problem.

Does someone has the same experiences before and can tell me how to resolve this issue?

Thanks a lot in advance.

Regards,

David
