[EnergyPlus_Support] Need help for simulating sensor faults in E+





Dear All,

I simulated offset of outdoor air temperature sensor in "FaultModel:TemperatureSensorOffset:OutdoorAir" as



  FaultModel:TemperatureSensorOffset:OutdoorAir,
    OATFault,                !- Name
    ALWAYS_ON,               !- Availability Schedule Name
    OATSeveritySch,          !- Severity Schedule Name
    Controller:OutdoorAir,   !- Controller Object Type
    VAV_1_OA_Controller,     !- Controller Object Name
    2.0;                     !- Temperature Sensor Offset {deltaC}



where the schedule "OATSeveritySch" is

Schedule:Compact,
    OATSeveritySch,          !- Name
    On/Off,                  !- Schedule Type Limits Name
    Through: 8/19,           !- Field 1
    For: AllDays,            !- Field 2
    Until: 24:00,            !- Field 3
     0,                      !- Field 4
    Through: 8/20,           !- Field 5
    For: AllDays,            !- Field 6
    Until: 24:00,            !- Field 7
     1,                      !- Field 8
    Through: 12/31,          !- Field 9
    For: AllDays,            !- Field 10
    Until: 24:00,            !- Field 11
     0;                      !- Field 12

However, I found that the 

Output:Variable,
    *,                       !- Key Value
    Site Outdoor Air Drybulb Temperature ,  !- Variable Name
    Hourly;                  !- Reporting Frequency


has no change.  In other words, there is no offset in this output variable.

May I know the reason?  Your answer will be very appreciated.
