AIRFLOW BALANCE
K Factor One Point Balance
1.
Change the Wall Module to the contractor view
2.
Navigate to PARAMETERS, FLO_CNFG, AREASQFT
3.
Verify the correct duct Area: AREASQFT
4.
Obtain the factory zone terminal K factor from the man-
ufacturer data sheet. If the K factor is unknown, use the
value 1400.
5.
Navigate to PARAMETERS, FLO_CNFG, K
6.
Set the factory K factor.
7.
Navigate to PARAMETERS, AIRFLOSP, MAX_FLO
8.
Verify the value of MAX_FLO setpoint.
9.
Navigate to PARAMETERS, BALANCE, K_OFFSET
10.
Verify that K_OFFSET = 0.
11.
Navigate to PARAMETERS, OVERRIDE, FLO_OVRD.
12.
Set VAV box override to the maximum occupied airflow
setpoint: FLO_OVRD = HISP
13.
Navigate to PARAMETERS, SENSORS, AIRFLOW
14.
Monitor AIRFLOW value.
15.
After the airflow has settled to a stable value, measure
the actual airflow with a calibrated instrument.
16.
Navigate to PARAMETERS, SENSORS, FLOPRESS
17.
Monitor the flow pressure.
18.
Calculate the new K factor: KFactorNew = AirflowMea-
sured / (FLOPRESS)1/2
19.
Calculate the K factor Offset: K_OFFSET = KFactorNew
– factoryKfactor
20.
Navigate to PARAMETERS, BALANCE, K_OFFSET
21.
Set the new K factor Offset value.
22.
Navigate to PARAMETERS, OVERRIDE, FLO_OVRD
Two Point (Min/Max) Balance
1.
Change the Wall Module to the contractor view
2.
Navigate to PARAMETERS, FLO_CNFG, AREASQFT
3.
Verify the correct duct Area: AREASQFT
4.
Obtain the factory zone terminal K factor from the man-
ufacturer data sheet. If the K factor is unknown, use the
value 1400.
5.
Navigate to PARAMETERS, FLO_CNFG, K
6.
Set the factory K factor.
7.
Navigate to PARAMETERS, AIRFLOSP, MIN_FLO
8.
Verify the value of MIN_FLO setpoint.
9.
Navigate to PARAMETERS, AIRFLOSP, MAX_FLO
10.
Verify the value of MAX_FLO setpoint.
11.
Navigate to PARAMETERS, BALANCE, K_OFFSET
12.
Verify that K_OFFSET = 0.
13.
Navigate to PARAMETERS, OVERRIDE, FLO_OVRD.
14.
Set VAV box override to the minimum occupied airflow
setpoint: FLO_OVRD = LOSP
15.
Navigate to PARAMETERS, SENSORS, AIRFLOW
16.
Monitor the AIRFLOW for stability at the minimum set-
point value.
17.
Navigate to PARAMETERS, BALANCE, MINFLOSP
18.
Set the minimum measured flow setpoint: MINFLOSP =
Avg(AIRFLOW)
19.
Measure the actual flow with a calibrated instrument.
20.
Navigate to PARAMETERS, BALANCE, MIN_FLOW
21.
Set the measured minimum flow calibration value:
MIN_FLOW = measuredValue
22.
Navigate to PARAMETERS, OVERRIDE, FLO_OVRD.
23.
Set VAV box override to the maximum occupied airflow
setpoint: FLO_OVRD = HISP
24.
Navigate to PARAMETERS, SENSORS, AIRFLOW
