Details – Remote operation switch
NOTICE
Remote operation switch. The unit is factory-equipped
with an operation switch with which you can turn unit
operation ON/OFF. If you want to remotely turn ON/OFF
operation of the capacity up unit, a remote operation switch
is required. Use a voltage-free contact for microcurrent
(≤1 mA, 12 V DC). Connect to X3M/1+2 class II
construction, and set to "Remote".

Details – Output signals
NOTICE
Output signals. The outdoor unit is provided with a
terminal (X2M class II construction) that can output 3
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.
