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.
Variable speed ECM Setup without an AID Tool
The blower speeds for G only, Low (Y1), and High (Y2/
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.
Variable speed 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.
ECM Speed Setup - These screens allow the technician to
select the G, low, high, and auxiliary heat blower speed for
the ECM blower motor. Change the highlighted item using
the
▲ and ▼ buttons. Press the ◙ button to select the speed.
After the auxiliary heat speed setting is selected the AID
Tool will automatically transfer back to the ECM Setup screen.
Cooling Airflow Setup - These screens allow the technician
to select -15%, -10%, -5%, None or +5% change from the
heating airflow. Change the adjustment percentage using
the
▲ and ▼ buttons. Press the ◙ button to save the change.
