Can anyone help me with locking out an indoor unit on a 2 pipe Daikin VRV111 system?
I have a problem with 1 of the indoor units not communicating due to faulty pcb but cant find a way to run the other 6 units while awaiting new pcb.

you need to disconnect the unit from the system and then run short wiring test

Sounds good and thanks. How would i go about that? I tried switching of at local isolator and run a system reset from outdoor unit. Remember doing this years ago and it working but may have been Tosh system.

yes that's the one just remove the wires from the unit and connect into terminal blocks sothe coms bypasses the unit then run the test
