What to do if my Bosch Controller is constantly OFF?
- DDavid Rush MDAug 10, 2025
If your Bosch Controller is constantly OFF, it could be due to a few reasons. First, ensure that the mains power supply is turned on. If the power supply is active, check the fuse and replace it if it's faulty, but only after switching off the power supply. Finally, a short-circuit in the BUS connection could be the problem; inspect the BUS connection and repair it if needed.
