SOURCE: will you tell me the electrical diagram of 12

Remove a door Usually the wire diag is on a cover. I do not under stand why you have so many model numbers. Unless its a generic label used on all the models. and in this case the diagram will most likely be for all them too with foot notes showing the differences. If this helps PLEASE GRADE ME ACCORDINGLY. IF not I need more information.

Daikin VRV J2

This is a fault with one of the standard compressor’s current sensors.
It occurs when the units PCB asks the compressor to run but then doesn’t recognise that the compressor is drawing any current. This can be due to a fault with the compressor contactor not coming in or a fault with either the Main PCB not giving an output to the contactor or not receiving the signal from the current sensor, or it could be a fault with the current sensor itself.
