Daikin remote controller

Instruction to retrieve Daikin error code using
the remote controller:

1) If your DAIKIN remote controller comes with a
"test" button, use it. Otherwise press the
Temperature UP, Temperature DOWN and the
MODE buttons all at the same time.

2) You will see 00 on the remote controller. The
first "0" will be blinking.

Stand facing the particular air conditioner you
wanted to test.

Now press the Temperature UP button, "0" will
become "A" and the air conditioner will respond
with either a single beep or double beep.

Carry on pressing the Temperature UP button
and listen to the beeping sound, stop when you
hear a double beep.
For example: it is now showing "C0".

Now press the MODE button, the second "0" will
be blinking.
Now press the Temperature UP button, "0" will
become "1" and the air conditioner will respond
with either a  double beep or a continuous beep.

The continuous beep is the error code. For
example "C4", it means it is a faulty liquid pipe
thermistor.
