I can confirm your settings on the Balmar are correct.
Are you sure the “dip switches”on th Mastervolt combi are all in the correct positions?
There is another thread here somewhere with pictures.
Has the TSB been completed or checked for the microwave/air conditioner circuit? It has been reported to interfere with the Relion BMS.
Again another thread on this forum with pictures.
After confirming all of this would think dealer would be next step.
