*1 00% CFM shown. CFM will vary pro portio nally with the gas valve B TU/H input.
4. Continuous fan speed is selectable at 25%, 50%, 75% or
100% of the furnace's maximum airflow capability.
Example: If the furnace's maximum airflow capability
is 2000 CFM, the continuous fan speed at
25% will be 0.25 x 2000 or 500 CFM.
5. Locate the blower speed selection DIP switches on the
integrated control module. Select the desired "cooling"
speed tap by positioning switches 1 and 2 appropriately.
Select the desired "adjust" tap by positioning switches 9
and 10 appropriately. Refer to the DIP switch chart for
switch positions and their corresponding taps. Verify CFM
by noting the number displayed on the dual 7-segment
LED display.

6. The multi-speed circulator blower also offers several
custom ON/OFF ramping profiles for cooling. These
profiles may be used to enhance cooling performance
and increase comfort level. The ramping profiles are
selected using DIP switches 7 and 8. Refer to the
bullet points below for a description of each ramping
profile. Verify CFM by noting the number displayed on
the dual 7-segment LED display.
• Profile A provides only an OFF delay of one (1) minute at
100% of the cooling demand airflow.

• Profile B ramps up to full cooling demand airflow by first
stepping up to 50% of the full demand for 30 seconds.
The motor then ramps to 100% of the required airflow. A
one (1) minute OFF delay at 100% of the cooling airflow is
provided.

• Profile C ramps up to 85% of the full cooling demand airflow
and operates there for approximately 7 1/2 minutes. The
motor then steps up to the full demand airflow. Profile C
also has a one (1) minute 100% OFF delay.

• Profile D ramps up to 50% of the demand for 1/2 minute,
then ramps to 85% of the full cooling demand airflow and
operates there for approximately 7 1/2 minutes. The

has a 1/2 minute at 50% airflow OFF delay.
