A 12-position DIP switch package on the control allows the airfl ow 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 fi rst "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 confi gured for the following P028
airfl ow settings.
Low Speed Fan: 500 CFM
Medium Speed Fan: 700 CFM
High Speed Fan: 900 CFM

Notes: Factory settings are at recommended L-M-H DIP switch locations.
Factory L setting is minimum allowed for cooling.
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 fi lter.
* With optional 1 HP fan motor.
