Setup -- Zoning
Disable Zoning:
S
NO (default)

This option allows actual temperature offset for each zone,
allowing calibration (or deliberate miscalibration) of each sensor.
Humidifier interval is time only, not actual humidifier run time.
Airflow Limits:
Since 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. For
setup guidelines, see Airflow Limits Checkout in the next section.
S
Low -- 100% of maximum assessed airflow
S
Medium -- 150% of maximum assessed airflow
S
High (default) -- 200% of maximum assessed airflow
S
Maximum -- no limit
Assessed airflow is determined as described in DUCT
ASSESSMENT.
Duct Assessment Time
1 p.m. (default), adjustable in 1 hour increments from 1 p.m. to 12
AM (24 hours). Select which hour of the day the duct assessment
will be performed.

Default is the cooling airflow. (350 CFM/ton)

blower will turn on.
