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

Factory settings are at recommended L-M-H DIP switch locations CFM is controlled within ± 5% up to the maximum ESP
M-H settings must be located within boldface CFM range Max ESP includes allowance for wet coil and standard filter
* With optional one horsepower fan motor Lowest and highest dip switch setting are assumed to be L and
H speed, respectively
A 12 position DIP switch package on the Premier E 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, and the third “ON” switch determines
the “High Speed Fan” setting.
The example to the right shows SW1 on the Premier E control board configured for the
following E036 airflow settings:
Low Speed Fan: 600 CFM
Medium Speed Fan: 800 CFM
High Speed Fan: 1200 CFM
