Off

A 12-position DIP switch package on the control allows the airflow levels to be set for low, medium, and high speed when using the ECM2 blower motor. Only three of the DIP switches can be in the "on" position.

• The first "on" switch (the lowest position number) determines the low speed fan setting.

• The second "on" switch determines the medium speed fan setting.

• The third "on" switch determines the high speed fan setting.

The example to the right shows SW1 on the control board configured for the following NS042 airflow settings.

• Low Speed Fan: 900 CFM

• Medium Speed Fan: 1150 CFM

• High Speed Fan: 1450 CFM

Setting Fan Speed - ECM

ECM2 fan motors have a 12-speed selector dip switch on the logic board (SW1) and are factory set for optimum perfor- mance. To change speeds, select the appropriate speeds on dip switch SW1. Consult the ECM2 fan performance table below for specific airflow and switch information.

CAUTION: Disconnect all power before performing this operation.
