A wireless temperature sensor that enables controlling the temperature in a different room than the room where the temperature controller is installed. The sensor is supplied from a lithium battery which enables its uninterrupted operation for 20 years.

The AURATON T-2 temperature sensor has the function of a radio transmitter and works with receivers that use the LMS communication protocol, such as AURATON RTH and AURATON 8000.


  • A factory-installed lithium battery of the highest quality made by SWATCH.
    Ensures continuous operation of the T-2 sensor for up to 20 years.
  • Interference-free communication between devices.
    Communication with receivers (AURATON RTH and AURATON RTF) at the 868 MHz frequency to ensure efficient and uninterrupted operation.
