Consider the following guidelines when you design a zoning system and layout:

  • Group zones with similar load profiles on the same RTU.
  • Keep perimeter zones separate from interior zones on the same RTU.
  • Make sure that each zoned RTU has a minimum of three to four zones.
  • Make sure that each zoned RTU supports a maximum of 32 voting zones.
  • When all zones are at a minimum airflow, size the bypass dampers for the remaining airflow volume. Use the following equation to size bypass dampers for the correct airflow:

    Bypass Airflow (cfm) = Unit Airflow (cfm) – All Zones Minimum Airflow (cfm)
