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.
If the Evolution Connex Control 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.
NOTE: The daily duct assessment will occur even if static pressure monitoring is
disabled. This is done to ensure that the system will continue to provide proper
airflow for all installed equipment, since duct system changes may occur at any
time, such as opened or closed registers.
After the duct assessment is complete, touch NEXT.
