RE: [EnergyPlus_Support] EMS Actuator

Unfortunately there are often legal issues attached to sharing some of my files.  I’ll see if I can recreate the error with a dummy file and send that.  The crash is related to the EMS because the main file runs fine and the sensor I made does not crash the run.  Just adding the actuator without a program specified crashes the run, so I suspect I am not specifying the right things to operate the steam.

I am trying to reset the watts on the following steam generator:

    EquipmentLevel,          !- Design Level Calculation Method
    50,                      !- Design Level {W}
    ,                        !- Watts per Zone Floor Area {W/m2}

    1,                       !- Fraction Latent
    ,                        !- Fraction Radiant
    ,                        !- Fraction Lost
    General;                 !- End-Use Subcategory
I assumed I could use an actuator:
    MoistureGain,            !- Name
    Direct Water,            !- Actuated Component Unique Name
    SteamEquipment,          !- Actuated Component Type
    Design Level {W};        !- Actuated Component Control Type
But this causes a system crash, so I must not be doing this correctly.  I also tried to manipulate the schedule and could not get the right values to avoid crashing.  Can someone give me a little guidance?
