IB FanOnOff

This object models a constant air volume fan that is intended to cycle on and off in tandem with a cooling or heating system (i.e., AUTO fan control mode). The fan can also operate continuously like {Fan:ConstantVolume}. If modeling continuous operation and this object is used as part of a system that utilizes {Coil:Heating:Fuel}, {Coil:Cooling:DX:SingleSpeed} or {Coil:Heating:DX:SingleSpeed}, the user should confirm proper air flow rates (coil and fan max flows are equal) and that the coil part-load fraction correlation(s) are appropriate (e.g., part-load fraction is less than or equal to 1 for all values of coil part-load ratio). If modeling multi-speed fan operation, this object must be used as part of a compound object that allows multiple fan speeds (e.g., {AirLoopHVAC:Unitary:Furnace:HeatCool}, {ZoneHVAC:PackagedTerminalAirConditioner}, etc.). In this case, the ratio of the compound object air flow rate to the fan's maximum air flow rate is used to determine the power at alternat....
