[Bldg-sim] 2 pipe FCU in EnergyPlus

[Chandan Sharma]

Hi Qinpeng,

Cooling coil availability schedule can be used to make it unavailable.

 From E+ IO Reference

Fan coil units can be 4-pipe or 2-pipe. For 4-pipe units there are 2 
supply pipes and 2 return
pipes. For 2-pipe units there is a single supply pipe and a single 
return pipe and the supply is
switched between hot and chilled water depending on the season. We model 
4-pipe units, but
the 4-pipe model can be used to model 2-pipe units by using the coil 
availability schedules to
make sure that either hot or chilled water is exclusively available.

Thanks,
Chandan
