Single Point Balancing
1.
Set Max cfm at
maxCoolFlowStpt (A228)
2.
Set
flowOverride (A258)
to
1
(max cool flow)
3.
Set
balanceModeHi (D204)
to
TRUE
4.
Allow
activeAirflow (A250)
to reach
maxCoolFlowStpt (A228)
5.
Enter the balancer's airflow in
KFactorFlowHI (A214).
6.
Again,
allow
activeAirflow (A250)
to reach
maxCoolFlowStpt (A228)
7.
Repeat as necessary.
8.
Calculated K factor
can be read at
activeKfactor (A293)
9.
To exit balancing, set
flowOverride (A258)
to
0
(Auto)
Two-Point Balancing
2-point balancing with the minimum flow can also be achieved by doing the
following:
1.
Set Min CFM at
minCoolFlowStpt (A227)
2.
Set
flowOverride (A258)
to
2
(min cool flow)
3.
Set
balanceModeLo (D45)
to
TRUE
4.
Allow
activeAirflow (A250)
to reach
minCoolFlowStpt (A227)
5.
Enter the balancer's airflow in
KFactorFlowLO (A245).
6.
Again,
allow
activeAirflow (A250)
to reach
minCoolFlowStpt (A227)
7.
Repeat as necessary.
8.
Calculated K factor
can be read at
activeKfactor (A293)
9.
To exit balancing, set
flowOverride (A258)
to
0
(Auto)
Note
: If the box has been 2-point balanced, the Active
K Factor
will reset between the low and high
K Factor
s
based on the active airflow.
Note
: If you are using a 3
rd
party interface such as
ASPECT®
or
INTEGRA™
for balancing boxes, make sure
K
Factor
points are written to
relinquish default
, and not to the
priority array
.
