2. The temperature rise must be within the range specified on
the rating plate.
NOTE: Air temperature rise is the temperature difference
between supply and return air.
With a properly designed system, the proper amount of
temperature rise will normally be obtained when the unit is
operated at the rated input with the recommended blower speed.
If the correct amount of temperature rise is not obtained, it may
be necessary to change the blower speed. A higher blower speed
will lower the temperature rise. A slower blower speed will
increase the temperature rise.
NOTE: Blower speed must be set to give the correct air
temperature rise through the unit as marked on the rating plate.
External Static Pressure Check
The total external static pressure must be checked on this unit to
determine if the airflow is proper.
Blower Speed Adjustments
Refer to the wiring diagram in "Troubleshooting" to verify the
speed tap settings.
Depending upon the model, blower speeds are changed at the
indoor blower. The ignition control board has 4 blower speeds:
Low Heat, High Heat, Low Cool and High Cool.
NOTE: Fan Only energizes at Low Heat speed.
The WGGE45 models are equipped with X-13 motors. X-13
motors are constant torque motors with very low power
consumption. This motor is energized by 24VAC. Adjust the CFM
for the unit by changing the 24VAC leads to the speed terminal
block on the motor.

NOTE: Heating airflow must be adjusted to provide the
temperature rise shown on the rating plate. A higher speed tap
may not provide more airflow. Blower speeds are programmed to
deliver adequate airflow at rated external static pressure (ESP).
Refer to airflow table provided in the Product Data Book
applicable to your model for details.
