Critical Things EkkoAir installation guide 10. When the you have configured the EkkoAir, check that it is set up correctly. In EkkoSoft, view the room in Viewer mode and look at the values for the ACU. The EkkoAir entry should show an airflow reading. Note: There may be a delay of several minutes before the readings from the EkkoAir are shown in EkkoSoft for the first time. This is because EkkoAir is designed to send data every 2 minutes (default) and EkkoSoft acquires data periodically. 11.
