EDIT AND TEST AIRFLOW PER ZONE
Adjustment to all air flows can be made either at the System
Devices > System
screen
or using the Edit and Test Airflow per Zone screen as illustrated in figure
20.The following procedure is to adjust individual zone airflow (CFM) for Blower
Circulation, Cooling and Heating airflow (see figure 20).
The
Maximum Airflow
for the selected mode on the left is displayed at the
top right of the screen.
The
Assigned Airflow
(the sum of the selected airflow for each zone) is
displayed at the top right of the screen.
NOTE - The airflow per zone (in red) must be selected and verified before
continuing.
1. Select the desired radio button option -
Blower Circulation Airflow
,
Cooling
Airflow
or
Heating Airflow
(
A
).
2. Adjust airflow for a specific zone by pressing on the desired zone (
B
). Total
maximum airflow for all zones in this example is a combined1250 CFM.
Minimum CFM per zone is
50
and maximum is
1250
.
3. Adjust airflow by using the up or down arrow to change the CFM (
C
).
4. Press
start
(
D
) to begin operation for that specific zone.
5. Repeat procedure to configure all applicable zones.
6. Press
save
(

the technician time to manually verify the equipment operation.
The
tests
feature is available after
setup
has been completed once. After you press
next
in the final
setup
screen, the “select tests to run” screen (figure 21) will appear.
(If you want you may skip tests; press

To run all of the tests, press
select all
. All boxes in the list of tests will be checked.
Or, touch box(es) next to test(s) to run certain tests.
After the tests have been started, the screen will describe which test is running and
shows a diagnostic summary of each test (see figure 22). After reviewing the results
and concluding that no further tests are needed, press
next
to proceed to next test.
The technician must verify that the test procedure is producing the desired result at
the equipment.
After pressing
next
after the final test, the “Testing finished” screen will appear
