NOTE
: The static pressure check occurs only at initial installation,
or when INSTALL is run in the INSTALL/SERVICE menu.
Duct Assessment
The following screen will appear after STATIC PRESSURE screen
is exited. Press right--side button 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.
A duct assessment will automatically occur each day at a user
selectable time. The factory default time is 1:00 p.m. but, may be
changed by entering the Zoning Setup menu. See Zoning Setup
section of this manual. The duct assessment will override a call for
heat or cool. The system will first open all zones and drive the
blower to 175 CFM/ton of cooling (or the minimum indoor unit’s
airflow, whichever is greater). It will then take a static pressure
measurement. The system will then close all zones and open one
zone at a time, taking a static pressure measurement for each zone.
The system will then close all zones and take a pressure
measurement, getting a value for the duct leakage up to and
through the dampers. With these static pressure measurements, the
system will calculate the relative size of each zone as well as the
percent leakage through the dampers At the end of the process, the
display will show the relative size of each zone duct. See Fig. 23.
If the User Interface detects an error (damper not moving or
damper wired backwards), it will perform the duct assessment
again. If it still detects a damper problem, it will default the
measurements into equal sizes, with 10% leakage, and display the
zone number for the suspected zone damper.
