@kimiya it doesn't look like your file upload worked, could you try again?

@kimiya It looks like your fans consume almost equal energy between all months of the year, which implies it is a constant-flow control. It would be hard to really debug without seeing more screenshots of fan input settings, or better yet, a link to the entire input file.

@kimiya it looks like you are using Detailed HVAC model option (HVAC tab is showing fields with green background). Therefore the fan availability schedule that you will need to adjust can be found at the HVAC component with fan eg. Fan coil unit dialog.
