Roof Top Unit—Two-stage gas heat and two-stage DX cooling with
economizer
This application applies to models BAC-4223CW0002, BAC-4023CW0002,
BAC-4203CW0002, and BAC-4003CW0002
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.
For single stage heating, do not connect W2.
For single stage cooling, do not connect Y2.
Connect outputs to 24 volt AC pilot duty inputs.
