Parametrics and EnergyManagementSystem

edit

I'm trying to combine the Parametrics feature with EMS, and getting an error. I'm using 8.5 Here is the definition of my parametrics:

Parametric:SetValueForRun,
    $SP_parametric,                  !- Parameter Name
    0,
    50, 
    100,
    500,
    1000;

And here is how I'm trying to use it in an EMS section:

EnergyManagementSystem:Program,
    Control0,                 
    IF Sensor0 < =$SP_parametric,     
    SET Actuator0 = VDG_clear,

The error I'm getting is:

 **  Fatal  ** EMS, caught unexpected token = "=" ; while parsing string=SENSOR0 < =$SP_PARAMETRIC

Is there a different way I should format the parameter reference so I can use it with the EMS?

Thanks
