[Trace-users] nominal ventilation for heating and cooling

[Oscar Buchely L.]

Thanks Hilary and Hayssam.

The system is constant volumen. In airflow I have NO in apply ASHRAE 
62.1 so Clg Ez and Htg Ez are not activated. I have tried ASHRAE Std 
62.1... vent resets and  Sum Room OA Reqs under System ventilation flag 
but still the Nom vent are not the same.
