S e c t i o n 5 : B alan c ing air flo w
Topics in this section are for control technicians or engineers who will be
balancing the airflow in the controllers.
The airflow balancing procedure described in this section requires the
following items.
A flow hood or other accurate method to measure airflow.
An STE-8001 or STE-8201 wall sensor. If the system does not include one
of these sensors, temporarily disconnect the installed sensor and connect
an STE-8001 as a service tool.
The engineering design specifications for the minimum and maximum
airflow setpoints.
Password 2 which is described in the topic Getting started with
configuration on page 26.
Note: If the VAV unit is a heat only or cooling only unit, the airflow setpoints for
the unused mode must be set within the range of the mode in use. Failure to
set the unused setpoints correctly will result in unpredictable or erroneous
air balancing settings. See Set the airflow setpoints on page 34 for the
procedure to adjust the setpoints.
Note: Starting the balancing procedure erases all previous airflow correction
factors. The airflow readings displayed by the STE-8001 are the actual
uncorrected airflow readings as measured by the controller.
Tip: Once the following procedure is started, all steps must be completed in
order.
