In the OS App, priority is based on the order the equipment is added to the zone or the order from top to bottom. So, to change priority, users unfortunately have to delete objects and reorder them.

Here's some Ruby code I've used to do that using the SDK. This will swap the first and second zone equipment order.

model.getZoneHVACEquipmentLists.each do |obj|

  clg_eqpt = obj.equipmentInCoolingOrder
  htg_eqpt = obj.equipmentInHeatingOrder

  obj.setCoolingPriority(clg_eqpt[0], 2)
  obj.setCoolingPriority(clg_eqpt[1], 1)

  obj.setHeatingPriority(htg_eqpt[0], 2)
  obj.setHeatingPriority(htg_eqpt[1], 1)  

end

Thanks Matthew. I use to edit the osm file and look for the OS:ZoneHVAC:EquipmentList and manually change the order. I was wondering if there was a better way or there was a measure to put in first position the air terminal unit.

Editing the OSM directly usually isn't recommended. Using the API/SDK is safer and the code above could be used in a formal OpenStudio Measure.
