[EnergyPlus_Support] Re: Fancoil units control

["anarui.oliveira" <anarui.oliveira@xxxxxxxxx>]

Don't think you can use a different kind of fan with the fancoil 
objet (other than constant volume, that is), but if you don't need 
the fancoil to supply outside air, independently of heating/cooling 
needs, maybe you can substitute the fancoil model by a "Unit 
Ventilator" model, which uses as On/Off fan, wich in turn can operate 
according to the heating/cooling needs.
