If your S1 does not display temperature data or display LLL, we recommend that you confirm whether the S1 Main Unit is correctly installed on the Base Unit and ensure that all contact points between the Main Unit and the Base Unit are in normal contact. You can watch our tutorial video to install it: ProTemp S1 Installation.

You can also reset S1 by pressing the RESET button next to the charging port to see if it can fix the issue. If it still fails, please take a video of the installation progress and send it to [email protected], and we will check and provide you with a solution.
