The mBox has a power socket with an ON/OFF switch located at the bottom right. Make sure the switch is in the ON position, denoted by the “I” mark. When the controller is powered, this switch should display a red indicator light.
If the light is not visible, follow these steps:
- Verify that the power cable is securely connected to the mBox controller and firmly plugged into a working wall socket.
- Review your home’s electrical panel to check if the breaker related to the mBox controller has tripped.
- Check the condition of the fuse. The mBox’s power socket houses a 10A fuse, with a spare 10A fuse in the fuse holder. If the fuse appears to be burned out, replace it with the spare one following the instructions in this article: How do I replace the fuse in Messana Controls’ devices (mBox and mZone)?
Always remember to disconnect the mBox controller from the power source before proceeding with this step.
