But the software is in english.
To change the entries download the data from your OSTC with OSTCConfig (you dont need status and profile for that), go to the "Temperature" Tab, click on "Allow edit" and change the value to whateveryouwant

Then, upload the Data to the OSTC.
Remark; After downloading the data, you have 5 minutes to do this, after the 5 minutes editing of these values will be switched off.
