independent of other airflow settings. To view airflows for normal air conditioning cooling

6.4.7. Humidifier

The humidifier can be exercised On and Off with this menu option. To end the humidifier

checkout, touch STOP.

6.4.8. Zoning (If Applicable)

NOTE: This feature is only available with specific ICP communicating indoor units. See the

Iont System Control Product Data for compatible units and more information.

6.4.8.1. 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.

6.4.8.2. 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.
