In the control library, you can find an external temperature override. This can be used to simulate full load systems or to set the external temperature on a specific value.
You need to connect one of the available generators to the override. In the simulation, the external temperature will exactly be the generated value.
You can also override the external temperature with your temperature data, by using a ‘.csv’ file and uploading it to a "file generator" Base Circuit.
In the first column of the CSV file , you type the time scale, for example from 1 to 8760 for one year.
On the file generator, you also need to specify that you are using an hourly time scale.
