setpoints
The airflow setpoints are limits for VAV unit operation. All values are entered by
a controls technician.
Minimum and maximum cooling airflow Sets the airflow limits through the VAV
unit when in the cooling mode.
Minimum and maximum heating airflow Sets the airflow limits through the VAV
unit when in the heating mode.
Setting the VAV
terminal unit
parameters
Terminal unit parameters set basic operating parameters and enable options
such as reheat and series or parallel fan operation.
Reheat
Not available on models BAC-8001 or BAC-8201.
Damper direction to close Defines which direction the damper will turn to
decrease airflow.
CCW—The actuator turns counterclockwise to close the damper.
CW—The actuator turns clockwise to close the damper.
Primary duct K-factor A property of the specific VAV unit and airflow sensor to
which the primary controller is attached. This constant is supplied by the VAV
unit manufacturer.
Fan operation Not available on models BAC-8001 or BAC-8201.
Balancing airflow An airflow balancing program is included in BAC-8000 series controllers. See the
manual STE-8000 and STE-8201 Sensor Installation Guide for balancing
instructions.
