NOTICE
Output signals. The outdoor unit is provided with a
terminal (X3M) that can output 4 different signals. The
signal is 220~240 V AC. The maximum load for all signals
is 0.5 A. The unit outputs a signal in the following
situations:
▪ C/C1: caution signal – connection recommended –
when an error occurs that does not stop unit operation.
▪ C/W1: warning signal – connection recommended –
when an error occurs that causes unit operation to
stop.
▪ R/P2: run signal – connection optional – when the
compressor is running.
▪ P1/P2: operation signal – connection mandatory –
when the indoor unit solenoid valve is being controlled.
