Comfort Mode Profiles
The multispeed circulator blower also offers several custom On/
Off ramping profiles. These profiles may be used to enhance the
cooling performance and increase the comfort level. The ramping
profiles are selected using DIP switches 5 and 6. See the “Profile”
illustrations for DIP switch positions and their corresponding
taps. Verify CFM by noting the number displayed on the dual 7-
segment LED display.
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 7¹⁄₂ 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 7¹⁄₂ 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 38°F for both stages which is
within the 20ºF to 50°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.
