What purpose does the VRF Supply Air Fan Operating Mode Schedule serve?

I am having some issues with unmet hours on my VRF system in OpenStudio and am trying to better understand the various fields associated with OS VRF systems. Which fan does the Supply Air Fan Operating Mode Schedule refer to? This appears to be separate from the overall Terminal Unit Availability Schedule as well as the availability schedule under the OS:Fan:OnOff section.

When I ran the ZEDF VRF with DOAS measure, this field came populated with an Always Off Discrete schedule. I am having significant difficulty resolve unmet hour for heating and cooling (seemingly a common complaint with this system) and am wonder if it could be related to this.

Thanks
