6.3.8.3. Airflow Limits
Since a bypass damper is prohibited in this system, this setting is used to
select the maximum allowable noise/airflow relationship into each zone
based on air noise and comfort requirements. LOW means 100% of
maximum assessed airflow; MED-LOW means 138% of maximum
assessed airflow; MEDIUM means 176% of maximum assessed airflow;
MED-HIGH means 214% of maximum assessed airflow; HIGH means
250% of maximum assessed airflow; and MAX means the equipment
does not stage down due to airflow, but the system may stage down due
to high static pressure.
CFM associated for each limit is shown on the screen. Compare this
value with the equipment's low stage CFM value to ensure that
equipment will run for each zone. Assessed airflow is determined as
described in DUCT ASSESSMENT.
After the selections are made, touch SAVE.
• Touch the zone name that you wish to change
• Select the zone to adjust airflow: Low, Med-Low, Medium,
Med-High, High, or MAX. Default = High
6.3.8.4. Duct Assessment Time
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.
This option allows the installer to select the time in which the duct
assessment will be performed. After the selection is made, touch SAVE.
• Duct Assessment Time: Selectable between 12 AM and 11PM.
Default = 1 PM
