TRACE 700 Outside Air values

TRACE 700 Outside Air values

TRACE 700 Outside Air values

(OP)
I am running TRACE 700 v6.0 and am struggling to meet the ASHRAE 62.1 outside air (OA) values within my heating outputs.  To correctly set the OA values, I have input the COOLING & HEATING ventilation values as the min OA values calculated using 62.1(from the CREATE ROOMS:AIRFLOWS tab).  The VAV min is set at 30% of Cooling airflow, and the main airflow are "To Be Calculated".  

HOWEVER, after calculating, the output only shows OA under the cooling category.  The Heating airflow numbers lists 0% OA, regardless of the ventilation value entered previously.

This is a variable-volume multiple-zone system with terminal boxes (heating only).

Has anyone else encountered this situation?  Am I doing something wrong, or is there a trick within the program to correct this?

TIA.
