Got a daikin VRV r407c with E9 had daikin come and look and told us to replace EEVS replaced all EEVS and still the same fault. swapped boards over with another unit reset same fault?! what else is there to change?!

It could be the out door PCB at fault not sending the signal it monitors the voltage to the heads

Expansion valve cables, also have you cleared the fault on the local controls. press the test button once on each control 'E9' will display (last fault) then push and hold ON/OFF button for over five seconds

Weve swapped outdoor boards put new heads on put new cables? Even daikin are confused

That's a hard one to work out . If daikin don't know. then its going to be down to them to work it out . Could be a fault that no one has come across for before . Let us know what happens good luck
