Blower Performance Data cont.
Setting Blower Speed - Variable Speed ECM
The ABC board's Yellow Config LED will flash the current ECM
blower speed selections for "G", low, and high continuously with a
short pause in between. The speeds can also be confirmed with the
AID Tool under the Setup/ECM Setup screen. The Aux will not be
flashed but can be viewed in the AID Tool. The ECM blower motor
speeds can be field adjusted with or without using an AID Tool.
ECM Setup without an AID Tool
The blower speeds for "G", Low (Y1), High (Y2), and Aux can be
adjusted directly at the Aurora ABC board which utilizes the push
button (SW1) on the ABC board. This procedure is outlined in the
ECM Configuration Mode portion of the Aurora 'Base' Control System
section. The Aux cannot be set manually without an AID Tool.
ECM Setup with an AID Tool
A much easier method utilizes the AID Tool to change the airflow
using the procedure below. First navigate to the Setup screen and
then select ECM Setup. This screen displays the current ECM
settings. It allows the technician to enter the setup screens to
change the ECM settings. Change the highlighted item using the
◀ and ▶ buttons and then press the ◙ button to select the item.
Selecting YES will enter ECM speed setup, while selecting NO will
return to the previous screen.
