Cooling Airflow Ramping Profiles
The multi-circulator blower also offers several custom
ON/ OFF ramping profiles. These profiles may be used to
enhance cooling performance and increase comfort level.
The ramping profiles are selected using the Cooling Airflow
Profile menu (if push buttons are used, use the CAP menu
to select the desired profile). Refer to the bullet points below
for a description of each ramping profile.

ramps up to full cooling demand airflow by first stepping up to 50% of the full

ramps up to 50% of the demand for 1/2 minute, then ramps to 85% of the full

then steps up to the full demand airflow. Profile D has a 1/2 minute at 50% airflow OFF delay.
Profile D(4 or 5)
In general lower heating speeds will: reduce electrical consumption,
lower operating sound levels of the blower, and increase the outlet
air temperature delivered to the home if heatmode is running.
If cooling mode is running the same airflow adjustment will
decrease the outlet air temperature delivered to the home.
The speeds available allow the blower performance to be
optimized for the particular homeowner’s needs.
