INTELLIZONE2 SPECIFICATION CATALOG
Blower Data - Package Unit
Airflow Selection (Single or Dual Capacity)
When equipped with a Variable Speed ECM airflow from
the Intellizone2 is communicated to the Aurora via a
'Blower Level %'. These blower levels are 55, 70, 85, and
100%. The Aurora will dictate actual airflow based upon
these percentages. Below is a graphic showing how the
IntelliZone2 would signal for a 55-100% blower level percent
and the resulting airflow based upon the ABC setpoints of
speed 5 for med and speed 8 for high in the example AID
Tool setting. Notice that a blower level of 85% would result
in a blower speed of 7 with these settings. All airflows are
rounded to the nearest 1-12 blower speeds. Continuous
blower and aux heat blower speeds are set Independently
of the compressor blower speeds.
In cooling a similar procedure occurs with the exception
that when dehumidification reduces airflow it is a reduction
as shown below. Therefore in dehumidification mode, if
blower speed 5 is selected the resulting airflow will be
blower speed 5, less 15%. If cooling airflow is configured to
be 15% less than heating airflow then there is no difference
between cooling and dehumidification cooling airflow.

(selection can be anywhere)
2) Aux Heat Airflow activated by Aux or Emergency heat call (selection
must be greater than high and allow proper airflow for the installed
electric heat/heat pump model)
Airflow Selection (Variable Speed)
Airflow from the IntelliZone2 is communicated to the
Aurora via a blower Level %. These blower levels are 25, 40,
55, 70, 85, and 100%. The Aurora will dictate actual airflow
based upon these percentages. Below is a graphic showing
how the IntelliZone2 would signal for a 25-100% blower
level percent and the resulting airflow based upon the ABC
setpoints of speed 3 for low and speed 8 for high in the
example AID Tool setting. Notice that a Blower level of 85%
would result in a blower speed of 7 with these settings.
All airflows are rounded to the nearest 1-12 blower speeds.
Continuous blower and aux heat blower speeds are set
Independently of the compressor blower speeds.
