Thanks for your help!

Hello, I would like to do natural ventilation based on both CO2 and ventilation schedule in EMS. And I have set two Sensors in EMS and set two programs. One is for CO2 concentration (above 1000 ppm, the window will open); and another one is a time schedule for venting (night ventilation). I would like to satisfy both conditions (CO2 concentration and time schedule) at the same time. However, it didn't work. The window can only follow one Program. I was wondering if someone could answer my question? Thanks very much!

Thank you so much. It runs.

Hello, I would like to do is when the CO2 reaches 1000 ppm, the window will open. And I used EMS set the C02 concentration of the zone as a sensor. However, there is always an error: "unique key name not found" in the file, showing on the following. I was wondering if anyone could tell me how to create a unique name in "EnergyManagementSystem: Sensor". Thanks in advance.

   **   ~~~   ** For Output:Variable or Output:Meter = ZONE AIR CO2 CONCENTRATION

Thank you so much. It works. Do you happen to know if EMS can do CO2 and Temperature in the same time? I did the progr
