What is the Air Balancing Tab?
Use the Air Balancing tab to perform air balancing and a duct heater airflow safety check. These
tasks are commonly performed during commissioning.
Currently this tab on the configuration page is only enabled with the enteliZONE eZV-440 VAV
controllers.
Variable Air Volume (VAV) System Commissioning
Air Balancing
The following procedure describes how to perform air balancing using the enteliZONE
configuration page.
This air balancing procedure is only supported on an enteliZONE eZV-440 VAV controller.
1. Enable Balancing Mode
Balancing mode is enabled a state in the Balancing Mode field by selecting a state other than
None_. When a state other than None_ is selected, the object OccupancyMode_ (MV800) is
automatically assigned a Balancing_ state.
2. Set the VAV Box Size
In the VAVBoxSize field, select the VAV box size you’re working with. Based on the VAV box size
you select, the algorithm then enters preset values in the following fields on the AirBalancing tab:
l FlowFactor
l CoolingMaximum (maximum cooling airflow setpoint)
l CoolingMinimum (minimum cooling airflow setpoint)
l HeatingMaximum (maximum heating airflow setpoint)
l HeatingMinimum (manimum heating airflow setpoint)
l StandbyMinimum
l Airflow controller tuning parameters (on the Controllers tab)
