11 ontractor: Blower Performance Data cont. Setting Blower Speed - Variable Speed EM he AB board s Yellow onfig LED will flash the current EM blower speed selections for, low, and high continuously with a short pause in between. he speeds can also be confirmed with the AID ool under the Setup/ EM Setup screen. he Aux will not be flashed but can be viewed in the AID ool. he EM blower motor speeds can be field adjusted with or without using an AID ool. Variable speed EM Setup without an AID ool he blower speeds for only, Low (Y), and High (Y2/ Aux) can be adjusted directly at the Aurora AB board which utilizes the push button (SW) on the AB board. his procedure is outlined in the EM onfiguration Mode portion of the Aurora Base ontrol System section. he Aux cannot be set manually without an AID ool. Variable speed EM Setup with an AID ool A much easier method utilizes the AID ool to change the airflow using the procedure below. First navigate to the Setup screen and then select EM Setup. his screen displays the current EM settings. It allows the technician to enter the setup screens to change the EM settings.
