Troubleshooting
Check power of main parts
Is CN77 cable
red ~ white/ white ~black/ red ~
black voltage AC380V?
Exchange two wires of 3 phase
incoming ones and press
the reset key (K3) and then retry.
P4 reappears?
Since it is the trouble on the 3 phase
detection circuit part, replace the PCB.
Measure the incoming part of 3 phase
power to find the problems on the
wire and circuit breaker for action.
Since the problems of incoming 3 phase
cable changed is solved,
normal operation is possible.

Judgment method
Causes
(Operation)
(Timer)
(Fan)
(Filter)
(Removing frost)
- One of the phase voltages or all of them are not incoming, comparing the
-
sequence of 3 phase circuit wave
-
(P4 error is automatically reset when the phase voltage is restored)
- l Incorrect connection of 3 phase power L1 (R), L2(S) and L3(T)/ 3 phase power is not on
●
Check items
- Check the 3 phase detection part power of outdoor unit PCB.
- Check the color of red, white and black of the cable for 3 phase detection part connectors L1(R), L2(S) and L3(T)
(Take care that the color and sequence are not changed.)
