OnOff
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 E040
airflow settings.
Low Speed Fan: 850 CFM
Medium Speed Fan: 1050 CFM
High Speed Fan: 1325 CFM

Notes: * With optional 1 HP fan motor.
Factory settings are at recommended L-M-H DIP switch locations. M-H settings must be located within shaded CFM range. CFM is controlled
within ± 5% up to the maximum ESP. Max ESP includes allowance for wet coil and standard filter. Lowest and highest dip switch setting are as-
sumed to be L and H speed, respectively.
