pressing and holding down SW6 on the control board of the outdoor unit for more

Release SW6 to confirm the reset once all the LED lights 2 through 9 have lit up.)
• If the outdoor unit’s and the indoor unit’s indoor unit address are not “000”, then it

Manual address setting instructions
Note: Manual address setting cannot be done on wall type indoor units.
1. The manual address setting is conducted by using the switch on each indoor / outdoor unit’s control board.
(Refer to the diagram below)
2. Set the power supply switch for all units to OFF. The address you set is stored when the power is turned on.
3. To change the address that is already set, turn the power supply OFF and reset the switch.
• The address number “000” cannot be used.
• Set the order for the unit address starting from “001” without skipping, as this facilitates the procedural tasks,
maintenance and inspection checks.
• Before switching on the power supply of the outdoor unit(s), ensure that the bus lines power supply is
switched on by setting switch SW5 to ON.
