This unit is factory set to run at the middle of the heating temperature rise range
as listed on the rating plate. The cooling speed is set to the maximum air

Three sets of 4 position movable jumpers are provided for Heat, Cool, and Adjust
taps for a variable speed motor. These tap jumpers apply signals to the ECM
motor without other interaction with the control board.
If the blower speeds require adjustment, follow these steps:
1. Remove the blower compartment door.
2. Locate the 4 position movable HEAT jumper to adjust heat speed.
3. Remove the jumper from position A and place it on the corresponding letter B, C, or D as required.
4. To adjust the cooling air
fl
ow ECM 2.3/EON, remove the COOL jumper from position A, and place it on the
corresponding letter B, C, or D.
Moving the ADJUST jumper from the NORM to the (+) or (-) position will cause the air
fl
ow to be increased or
lowered by 15%.
The TEST position on the ADJUST tap is not used.
NOTE:
Temperature rise should
always be re-checked
whenever blower speed
is changed.
