economizer
This application applies to models BAC-4003CW0002, BAC-4023CW0002,
BAC-4203CW0002, and BAC-4223CW0002.
Fan status switch (FST) is optional. Typically it is used only when the
AppStat is connected to a network.
Discharge air temperature (DAT) and outdoor air temperature (OAT)
sensors are required for economizer operation.
For dehumidification, the AppStat must include a humidity sensor.
The remote temperature sensor (RS) is optional.
Connect the fan output to a 24 volt AC pilot duty input.
