VAV and CAV Conﬁ gurations

Application Conﬁ gurations

This area of the manual is designed to simplify the programming setup

process for typical AAON

units that have factory installed SA Con-

trollers. Special applications are also included to guide you through

the setup process for more complicated conﬁ gurations. The following

conﬁ gurations will step you through the Conﬁ guration Section of this

manual. Not all conﬁ guration screens are listed in this section. This sec-

tion is more of a quick setup guide for basic applications. Please read

each description under the corresponding Conﬁ guration Screen in this

manual to see if that option applies to your application. Setpoints are

not shown here since they are not necessarily conﬁ guration- speciﬁ c,

but are based more on job requirements. Read the descriptions under

the corresponding Setpoint Screens in this manual to understand which

setpoints to use and what values are appropriate to enter.
