Example:
Opening dampers
In our example, we want to open all the dampers of the vavs that the AHU is serving.
So we select AHU-1 and open the AHU Air Balance tool. Then select to Open all vav dampers to 100%. Below you can kind of see the damper for Vav-01 at 76%.
After we hit apply, you'll get a popup to double check to make sure the AHU is off to not cause too much pressure. Then it'll take us to the folio app to display all the dampers that it changed.
You can also see Vav-01 Damper was commanded to 100% when before it was 76%. The same process goes if you want to close them to 0% or to release them to auto.
