Why does my VER-MAC Controller show a 'Device error'?
- HHeather EvansAug 5, 2025
If your VER-MAC Controller shows a 'Device error', it means there's a communication issue with one of the components. To troubleshoot, use the maintenance menu. An 'X' on one of the lamps indicates a problem in that specific area. If 'Err.' is displayed everywhere, it suggests a possible defective solar regulator.
