Hey everyone,

I believe it would be a good idea to have this as a separate question and not link it with my previous one.

After further investigating the previous script. A schedule control was also needed to be incorporated into my EMS script where the schedule calls the window to open for 15 minutes twice a day. Unfortunately, the results aren't looking like how they should.

EnergyManagementSystem:Sensor,
    NatVentSchedule_Sensor01,        !- Name
    AtticBedroom-cutout,  !- Output:Variable or Output:Meter Index Key Name
    Zone Mean Air Temperature;  !- Output:Variable or Output:Meter Name
EnergyManagementSystem:Actuator,
    OpenFactorSchedule,            !- Name
    Natural_Ventilation_Test,  !- Actuated Component Unique Name
    Schedule:Year,        !- Actuated Component Type
    Schedule Value;  !- Actuated Component Control Type
EnergyManagementSystem:Program,
    CO2_Sensor01,            !- Name
    IF (EMS_CO2_Sensor02 > 1000) || (Temperature_Sensor02 >= 23) || (NatVentSchedule_Sensor02 > 0.2) ,  !- Program Line 1
    SET OpenFactor01 = 1.0, !- Program Line 2
    SET OpenFactorSchedule = 1.0, !- A4
    ELSE,  !- A5
    SET OpenFactor01 = 0.0,  !- A6
    SET OpenFactorSchedule = 0.0, !- A7
    ENDIF;  !- A8

The schedule is an On-Off schedule with 1 calling the window to open. When I look at my indoor CO2 levels and the EUI, it looks to be that the window opens throughout the day.

I would appreciate it if anyone could help me out with this script.

Cheers, Adarsh
