<p> It is not really possible to know what might be going wrong without running the project. What I would suggest is that you make a new project to which you add only the exhaust and outdoor air fans. Make sure they are the right size by adjusting parameter
values and run the simulation using an online plotter to verify that the temperature, humidity and flow rate leaving the fans is as you planned for it to be. Next, add the heat wheel into the system. Again, make sure that the parameters are correctly set so
that the heat wheel is appropriately sized to the application. Again, use the online plotter to verify that the temperatures, humidities, and flow rates exiting the wheel make sense. Keep adding one component at a time and verifying as you go.<o:p></o:p></p>
<p> kind regards,<o:p></o:p></p>
