6.4.9. Zoning (If Applicable)
6.4.9.1. Airflow Limits
Because there is no bypass damper, the zone airflow limit check will
allow the installer to assess the airflow noise generated by the system
providing the maximum amount of airflow to each zone. Touch
AIRFLOW LIMITS: When START is touched, the selected zone's
damper will fully open, all others will close, and the indoor unit will
provide the maximum airflow for that zone (as selected in SETUP —
ZONING, Airflow Limits). If the airflow noise is objectionable, the
installer can select a lower airflow noise limit. If the noise is not
objectionable, the installer should leave HIGH selected, or even NO
LIMIT.
NOTE: Selecting a lower airflow noise limit may decrease the
homeowner's comfort in that zone.
Touch the Left (<) or Right (>) buttons to change the desired zones. Once
the proper airflow limits are set, touch SAVE, to see ZONING
CHECKOUT menu.
6.4.9.2. Damper/Sensor Check
The Sensor/Damper Check allows the installer to check each zone
damper for operation, as well as insure the zone sensor corresponds to
that particular zone. When first initiated, the Zone 1 damper will fully
open, and all other zones will close. Using the Left (<) or Right (>)
buttons, the installer can select each zone and verify the damper is fully
open while all other dampers remain closed.
After proper damper operation has been verified, the installer can now
check and verify that each Remote Room Sensor corresponds to the
