RJ SERIES INSTALLATION MANUAL
Setting Fan Speed
ECM2 fan motors have a 12-speed selector dip switch on the 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.
CAUTION: Disconnect all power before performing this operation.

On 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 042 airflow settings.
Low Speed Fan: 900 CFM
Medium Speed Fan: 1150 CFM
High Speed Fan: 1450 CFM

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
Lowest and Highest DIP switch settings are assumed to be L and H respectively
