The following models are compatible with the outdoor units with low standby power control.
Connecting the following models to the MXY series with the low standby power control enables the low standby power control.
The following models may be connected to the MXY series with the low standby power control after once connected to the
MXY series without the low standby power control and operated, for example because of relocation. In that case the MXY ser-
ies with the low standby power control will not operate unless taking a step. Follow the procedure “Deleting the memorized
abnormal condition” described in 10-2.1.
