[1] The Hardware is protected against overtemperature above 114 °C. Since the software has its own temperature protection object which is set to 100 °C by default, this hardware protection will not be triggered.
[2] Fast ABI is supported from firmware 5.0 on
- [3] Using a PT100 is not recommended. Click here for details about temperature sensors
