Roof Top Unit—Two-stage gas heat, chilled water cooling with
modulating valve and 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 staged heating and fan outputs to 24 volt AC pilot duty inputs.

For single stage heating, do not connect W2.
