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. TouchAIRFLOW LIMITS:When
STARTis 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 leaveHIGHselected, or evenNO LIMIT.
NOTE: Selecting a lower airflow noise limit may decrease the homeowner’s
comfort in that zone.
Touch the Left () buttons to change the desired zones. Once the
proper airflow limits are set, touchSAVE,toseeZONING CHECKOUTmenu.
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 () buttons, the installer can select each zone and
verify the damper is fully open while all other dampers remain closed. 
						

							47
After proper damper operation has been verified, the installer can now check and
verify that each Remote Room Sensor corresponds to the proper zone damper in the
same zone. For systems with remote room sensor, temporarily disconnect any other
zone Remote Room Sensor (at sensor location). That zone damper will now open,
while the Zone 1 damper will close.
For systems using Smart Sensors, the installer may press and hold the Hold and
Mode buttons simultaneously for 3 seconds to change the zone under test. This
should be done with each zone to verify that the zone sensor corresponds to that
particular zone.
Once each zone has been checked, touchDONEto return to theZONING
CHECKOUTmenu.
6.4.9.3. Zone Duct Assessment
This screen shows the results from the previous duct assessment. The duct
assessment is performed at initial start --up and at 1 P.M. or the installer selected time
each day. If another duct assessment is desired, the service technician should
perform a re --install of the system.
NOTE: A Duct Assessment will automatically occur every 24 hours at selected
time to check system static and calibrate dampers.
Once the duct assessment is complete, touchDONEto return to theZONING
CHECKOUTmenu.
6.4.9.4. Sensor Type
This option shows a list of all zones with corresponding sensor types.
