Hi there.
Does anyone out there have the fault codes for daikin units
i have no problems so far but i have started to service alot of them lately and would like to have the info if needed nothing worse than the customer asking what it means and you dont no..
Thanks.

And if you are working on the VRV, here's a link to the centralised controller and fault codes. A handy guide :) http://www.daikinac.com/pdf/op_manual/DCS302C71.pdf

Thanks for the codes they will be very handy at least a wont have to stand there looking puzzled if i see them on the screen..
cheers..

i need some help about Daikin Split unit.I had replace a PCB on the outdoor unit with the same setting which were on the old one ( visual).After starting i got a fault "PJ" ( PJ Outdoor Failure of capacity set resistor ).Can someone tell me how to solve that problem.Thanks in advance.

What is the outdoor unit type?.
You have to set Capacity Adapter to PCB which tells outdoor unit 'size'. (Spare parts PCB don't have 'size' settings in it.)
Hopefully this helps.

The replacement PCB should have been supplied with a small plug and wire loop which needs to be fitted to the PCB in accordance with the instructions with the board.
This sets the capacity of the unit.

inormally just use the new daikin text service text them the fault code and they reply within seconds excellent or even better ring them if your confused good luck

THanks for the fast replay.With the PCB have not arrive with a plug i checked few times.The model number is : RYEP100L7W1.Is that mean that i need just to plug it in and it will start working or there is another steps which have to be done? Thanks in Advance.

Look at the boards side by side, on the original board you will find a plug that's not on the new board (normally it's a plug with a looped cable in it but there are other versions, just a plug with internal short, the cable replaced by a resistor are the ones that springs to mind).
Then just move the plug across.

I've had this many times on replacement indoor boards but never on an outdoor board?? :confused:

Forgot all about it until I powered it up and got the fault code.
Found the capacity plug taped to the underside of the packing neatly stuck to the bubble wrap :)

I checked- nothing.Most probably the company installed has removed them from the unit if there is or the DAIKIN company miss to fit one in the box.
Is that mean that
