Why the fan schedule is not working?

Hi,

I´ve been working in a HVAC system and I am facing a problem regarding to the fans that I had applied to my model. The fan is a constant volume fan. I made a schedule in order to turn the fan off during the weekends and between time period of 7:00pm and 7:00am during week. Then I associated this schedule to each fan. The result shows no reduction in the energy consumption if compared with the case in which the fans are kept turn on 24 hours per day, and every day of the week. It seems that the schedule made by me it is not being working. A bring some pictures here to show in details how I am dealing with it. My conclusion is based on the fan consumption which remains the same, even when my schedule is applied and in the zone mechanical ventilation, which shows that this fan is working continuously, without interruption (last picture).
