5.11. Airflow Verification Check
The airflow verification check screen will appear next, as the system performs this
operation. This process will take about 1--1/2 minutes to complete. When
completed, a screen will appear displaying the results of the check.
If the system has an indoor unit equipped with a previous--version CFM--controlled
blower system, the screen will display the static pressure (in inches of water) across
the equipment at the expected highest delivered airflow. If the blower RPM is
greater than 1200, a warning will appear, but equipment operation and the
TrueSense
t
dirty filter detection operation will not be affected. Press
NEXT
when
the airflow verification check is complete.
If the system has an indoor unit equipped with an updated--version CFM--controlled
blower system (typically found in equipment manufactured after September 2015),
the screen will display the static pressure (in inches) across the equipment at a
pre--determined target airflow CFM. If the achieved (actual) CFM is unacceptably
below the target CFM, a yellow notice will appear to invite the user to see the
associated information screen; equipment operation and the TrueSense
t
dirty filter
detection operation will not be affected. Press
NEXT
when the airflow verification
check is complete.
NOTE
: The airflow verification check occurs at initial installation, or when
FULL
INSTALLATION
or
AIRFLOW VERIFICATION TEST
are selected in the
INSTALLATION & SERVICE
menu.
5.12. Duct Assessment (zoned systems only)
The duct assessment screen will be displayed next for zoned systems. Touch
NEXT
to start Duct Assessment. Duct Assessment will measure the relative size of the
ductwork, up to and through the dampers. These measurements are used to control
the correct amount of airflow in the zoned system. Status messages will appear on
the screen to indicate what the system is doing. The process will take approximately
one minute per zone. The duct assessment will override a call for heat or cool.
