This error occurs when the unit detects an imbalance in the current, which could be from the vehicle, the charge point or even something completely external , for example an increased load on your local electricity supply.
The red LED will continuously flash when an RCM error has occurred.
You can reset an RCM error by pressing the multifunction button twice, or by performing a hard reset.
RCM errors are completely normal and can happen every so often, but if you are experiencing recurring RCM errors, please get in touch with our support team.
