I have found by the variable output that the zones with set point not met during these specific period have no change in the temperature of air entering and leaving the AirTerminalUnit.

then I have tried to investigate the Coil:heating:water of every zone, there is temperature drop in enertering and leaving water, I dont understand why there is temperature drop in the water heating coil and no temperature increase in air which leaving ATU?

I have checked the flow rate water and air enerting to ATU and compare with the zone with having met all setpoints. and i found even there is higher flow rate for water and air for the zones with unmet hours. After certain level there is flow rate of water have been maximum during this period and same for many hours in this period.

I have compare Water and air temperarature and water and air flow rate for two thermal zone with setpoint not met with normal zones, please have a look and give some feedback.

@Yagnik can you edit your post to include images to show what results you're seeing? Better yet, can you upload your model to Google Drive, Dropbox, etc. and then share a URL for others to download? That would help others provide better solutions.
