TEC Controller Firmware Update FW v5.01

We inform you that from 1st December 2021 all newly delivered TEC Controllers will be programmed with the updated firmware version v5.01 by default. Please let us know if you need another firmware version on your TEC Controller.

The most important changes:

  • Improvement of the computing resolution for the temperature measurement with NTC sensors.
  • Bugfix: Adjustment of the measurement frequency for the internal supply voltage in order to avoid aliasing effects --> Error 37 (Internal 3.3V power net > Hard Limit) doesn't occur false positiv on the TEC-1091.

The new firmware version is 100% hardware compatible with all hardware versions of the TEC controller family. Please note: Devices with FW v5.00 can be updated by yourself; FW versions lower than v5.00 have to be sent to us for an update (but update is not mandatory).

Detailed information can be found in the attached TEC Software Release Notes.

If you have any further questions or concerns, please do not hesitate to contact us. We will be glad to help you.

Best regards and stay healthy!
