Profile A
■
Provides a 1-minute Off delay at 100% of the cooling
demand airflow.
Profile B
■
Ramps up to 50% of the full cooling demand airflow for
30 seconds.
■
The motor then ramps to 100% of the required airflow.
■
Provides a 1-minute Off delay at 100% of the cooling
demand airflow.
Profile C
■
Ramps up to 85% of the full cooling demand airflow for
approximately 7
¹⁄₂
minutes.
■
The motor then ramps to 100% of the required airflow.
■
Provides a 1-minute Off delay at 100% of the cooling
demand airflow.
Profile D
■
Ramps up to 50% of the full cooling demand airflow for
30
seconds.
■
Then ramps to 85% of the full cooling demand airflow for
approximately 7
¹⁄₂
minutes.
■
The motor then ramps to 100% of the required airflow.
■
Provides a
30
-second Off delay at 50% of the cooling
demand airflow.
6. Select the heating speed from the heating speed chart in the
Specification Sheet for your model. The Adjust Taps setting
(already established by the cooling speed selection)
determines which set of speeds are available. The selected
speed must provide a temperature rise within the rise range
listed with the particular model.
Example: The WGFM290508V4C is set for 990 CFM on
cooling, the “ADJUST” is set to “+” (plus). The 4 heating
speeds available are “A Plus,” “B Plus,” “C Plus” and “D
Plus.” “A Plus” has a rise of 46°F for both stages which is
within the 30-60°F rise range for the WGFM290508V4C. This
setting will keep electrical consumption to a minimum. Set
the “Heat” speed DIP switches to “A.”
7. Select the desired heating speed tap by positioning DIP
switches 7 and 8 appropriately. Verify CFM by noting the
number displayed on the dual 7-segment LED display.
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. The
speeds available allow the blower performance to be optimized
for the particular homeowner’s needs.
To Set Airflow
1. Select the model and desired high-stage cooling airflow.
2. Determine the corresponding tap (A, B, C, or D).
3. Set DIP switches 1 and 2 to the appropriate On/Off positions.
4. Select the model and desired high-stage heating airflow.
5. Determine the corresponding tap (A, B, C, or D).
6. Set DIP switches 7 and 8 to the appropriate On/Off positions.
7. Select the airflow adjustment factor taps (A and D are 1; Tap
B is +10; Tap C -10).
8. Set DIP switches 3 and 4 to the appropriate On/Off positions.
To Set Comfort Mode
1. Select desired comfort mode profile. See Comfort Mode
Profile chart.
2. Set DIP switches 5 and 6 to the appropriate On/Off position.
