Programming The VCM Controller
Application Configurations
This area of the manual is designed to simplify the programming setup
process for typical AAON
® units which have factory installed VCM
Controllers. Special applications are also included to guide the user
through the setup process for more complicated configurations. The
following configurations will step you through the Configuration Sec-
tion of this manual. Not all configuration screens are listed in this sec-
tion. This section is more of a quick setup guide for basic applications.
Please read each description under the corresponding Configuration
Screen in this manual to see if that option applies to your application.
Setpoints are not shown here since they are not necessarily configura-
tion specific, but are based more on job requirements. Read the descrip-
tions under the corresponding Setpoint Screens in this manual to under-
stand which setpoints to use and what values are appropriate to enter.
