OnOff
A 12-position DIP switch package on the control allows the air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 rst “on” switch (the lowest position number) determines the low speed blower setting. •
The second “on” switch determines the medium speed blower setting.•
The third “on” switch determines the high speed blower setting.•
The example to the right shows SW1 on the control board congured for the following N040 airow settings.
Low Speed Blower: 900 CFM
Medium Speed Blower: 1150 CFM
High Speed Blower: 1450 CFM
