Description
nciBalanceSetPts
BoxZeroOffset
SNVT
press_f
0
pascal Airflow pressure sensor zero calibration offset. This value is
subtracted
from the sensor input.
Precision: 1
KFactorOffset
SNVT
count_inc_f
0
VAV Box cooling air K factor calibration parameter. This factor is
used by the Balancing tool to increment the factory K factor
setting. The Offset value is
added
to the factory value.
Precision: 0
MaxMeasFlowAct
SNVT
flow
1000
CFM
The actual cooling flow measured at the max flow setting during
the two point airflow balancing process. (optional)
0
≤
range
≤
138850 cfm
Notes:
This value is set by the flow balancing tool.
Set the value to 1000 to disable two point calibration.
Precision: 0
MaxMeasFlowSpt
SNVT
flow
1000
CFM
The actual cooling flow maximum setpoint during the two point
airflow balancing process. (optional)
0
≤
range
≤
138850 cfm
Notes:
This value is set by the flow balancing tool.
Set the value to 1000 to disable two point calibration.
Precision: 0
MinMeasFlowAct
SNVT
flow
0
CFM
The actual cooling flow measured at the min flow setting during the
two point airflow balancing process. (optional)
0
≤
range
≤
138850 cfm
Notes:
This value is set by the flow balancing tool.
Set the value to 0 to disable two point calibration.
Precision: 0
MinMeasFlowSpt
SNVT
flow
0
CFM
The actual cooling flow minimum setpoint during the two point
airflow balancing process. (optional)
0
≤
range
≤
138850 cfm
Notes:
This value is set by the flow balancing tool.
Set the value to 0 to disable two point calibration.
Precision: 0
nciCO2Vent
Configuration for indoor air quality ventilation control.

SNVT
ppm
900
ppm
High Room CO2 level associated with the highest flow reset
setting:
MinFlo FractionOfMaxAirFlow*MaxFlowSetpt
range: 300 to 1200 ppm
default value: 900 ppm
