* Factory Setting
* In the case of applying high voltage to the terminal 1 and 2 of TB2,
the 0.5A fuse on the PCB is cut. In such a case, first reconnect the
wirings correctly to TB2, and then set the No.1 pin to ON.

● The "■" mark indicates setting for DIP switches. Figures show setting before shipment.
● When the unit number and the refrigerant cycle are set, record the unit number and refrigerant cycle to
facilitate service and maintenance thereafter.
Turn OFF all power supply of the indoor units and the outdoor units before DIP switch settings.
Otherwise, the setting will be invalidated and not take effect.
