Hi,

I want to know if it´s possible to simulated a mixed mode system in Enegy Plus. 

My project is a residential building with natural ventilation in every apartment and water cooled VRF. 

I am using the HVAC Templates to simulate the VRF system, but I want to know how can I set up the mixed mode system? Which type of control should I use? As I want the VRF  turn on when the windows are closed and the other way around. 

Hope you can help me!
