Hi guys! I have a problem with the calculation of the AFN Linkage Node 2 to Node 1 Volume Flow Rate. I work with a graphical interface: DesignBuilder, where I created my model that has two exterior windows and a door, and I set the natural ventilation system (I simply put "activities" of the natural ventilation control temperature to zero, so that, as explained in the guide, the windows can be opened according to the opening program I entered) but when I go to do the simulation in E + the windows do not open in the opening hours that are set by the schedule, but at times that are not in any of the schedule that I have entered. For example, I have an opening time from 8 am to 10 am but my windows open at 6.50 till 7 am. have you ever had this problem? how you solved it?

Ps I checked if the schedule of the openings had been imported correctly by DesignBuilder to EnergyPlus and they are all correct.
