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 Ion System 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.
