PerformanceData

AIRFLOW ADJUSTMENTIf the airflow needs to be increased or decreased, see theAirflow Label on the air handler or the Blower PerformanceTable in the Service Facts. Information on changing the speedof the blower motor for your specific outdoor model size is in theBlower Performance Table.

Blower speed changes are made on the ECM Fan Control. TheECM Fan control controls the variable speed motor.

There is a bank of 8 dip switches (see Figure 1), located at theupper part of the board. The dip switches work in pairs to matchthe airflow for the outdoor unit size (tons), cooling airflowadjustment, cooling off delay options, and heating airflowadjustment. The switches appear as shown in Figure 2.

* - This setting is equivalent to the BAY24X045 relay benefit

** - This ENHANCED MODE selection provides a ramping up and ramping down of the blower speed to provide improved comfort, quietness, and potential energy savings. The graph shows the ramping process.
