Daikin controller faults

[Kirky]

3 seperate daikin multi split systems cooling a large office. All 3 systems shutdown not showing any fault codes except a icon on the controllers showing that all 3 systems are being controlled by a primary controller. As far as I am aware these systems are independant from each other. If I switch off one of the 3 systems at the breaker the other 2 will run fine, doesnt matter which one I turn off. Any ideas ???

Do these have KRP boards? Thats usually what it means if there is no centrall controller.
If they have then disconnect the krp boards and test the system with out them.
If everything works fine then you know there is an issue with the boards, probably not wired/set correctly.

Crossed wiring?
