  It sounds as though you have an incorrect connection in your project 
or as though there is a units problem (like mixing up a mass flow rate 
of ventilation air (kg/h) with an air change rate (airchanges/hr). 
Without seeing the project it is not possible to tell. I would recommend 
you contact your distributor for technical assistance.
