Re: [EnergyPlus_Support] Coil on off according to humidity ratio

["Jim Dirkes jim@xxxxxxxxxxxxxxxxxxxxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

I use a simple EMS program for turning off DX coils below a specified outdoor temperature.  Something similar may work for you and humidity ratio.

EnergyManagementSystem:Sensor

OutdoorTemp

Environment

Site Outdoor Air Drybulb Temperature

EnergyManagementSystem:Actuator

DXLowLimit1

Sched_LowTempClgOFF

Schedule:Compact

Schedule Value

EnergyManagementSystem:ProgramCallingManager

DXLowLimit Management1

BeginTimestepBeforePredictor

DXCoilControl1

EnergyManagementSystem:Program

DXCoilControl1

IF (OutdoorTemp < 12.8)

SET DXLowLimit1 = 0.0

ELSE

SET DXLowLimit1 = Null

ENDIF

I want to make coil available (on) when humidity ratio (w) is above certain value and off if below .

Is there a way the program can decide that automatically without the need to creating an excel schedule file ?
