It does seem that you may have a load monitor fitted which can be adjusted?I spoke to Alde who could only suggest a crimped wire or pest infestation none of which I can find.I have read that when the alde system is shut down unexpectedly as has happened many times here in the Netherlands due to us demanding more amps than we have access to,the alde system will throw up errors .
I have reset the system back to factory settings but still the error is there.
