[EnergyPlus_Support] airflow network influenced by zone controls? ventilation setpoint does not work

["astroid8@xxxxxxxxxxxxxx" <astroid8@xxxxxxxxxxxxxx>]

Dear all,

I got stuck with two questions regarding the airflow network system:

I am modelling an airflow network system for natural ventilation,
using the ventilation control mode "temperature". my setpoint
temperature above which the windows should be modelled open is 22°C.
However if I look at the output (zone/sys air temperature) I can also
find hours with opened windows even if the zone temperature is
slightly below 22... What is my mistake?

Additionally I want to calculate the cooling loads to a certain
setpoint, so I use dual setpoint with deadband at zone control
thermostatic. How is it possible to switch off the natural ventilation
(i.e. assume closed windows) defined in airflow network system while
the cooling system is running? 

I would be happy about some help,

Regards, Astrid
