ENHANCED
Indoor Blower Timing
This ENHANCED MODE selection provides a
ramping up and ramping down of the blower
speed to provide improved comfort, quietness,
and potential energy savings. The graph on the
right shows the ramping process.
•
Set the S2-5 dip switch for the airflow mode.
AIRFLOW MODE
*TORQUE
CONSTANT CFM
* Torque mode is optional and is recommended for high static
applications. High static conditions dramatically increase energy
consumption with variable speed motors. Evaluate the blower
performance table in relationship to the duct system to determine
the benefit of each installation.
* Torque mode will reduce airflow when static is above approxi-
mately 0.4" water column.
* All heating modes default to Constant CFM.
