Fan Coil Unit—Four-pipe with modulating fan and modulating valves
This application applies to models BAC-4008CW0001, BAC-4028CW0001,
BAC-4208CW0001, and BAC-4228CW0001.
Fan status switch (FST) and discharge air temperature sensor (DAT) are
optional. They are typically used only when the AppStat is connected to
a network.
For dehumidification, the AppStat must include a humidity sensor.
The remote temperature sensor (RS) is optional.
Valves are 24 Volt AC.
Fan start output is for a 24 volt AC pilot duty input.
Fan speed input is 0-10 volts DC.
For additional details on connecting sensors, see Connecting inputs on
page 20.
For additional detail on connecting the fan and valves, see Connecting
outputs on page 24.
