The settings stored in the EEPROM of the P .C. board for indoor unit servicing are the factory-set values.
Step 1 In STOP status, push [MENU] and [▼] buttons simultaneously for at least 10 seconds.
• In the air-conditioning group control mode,
system address (the value of the refrigerant piping system is the same as the number of outdoor units,
and one outdoor unit is displayed as 1). The indoor unit address is represented by N. The indoor unit
number displayed first is the main indoor unit number.
• In the non-group control mode (only one indoor unit), only 1-1 is displayed on the left.
(If the auto-address setting mode is interrupted in [2] step 2a, the unit No. [all] is displayed)
Step 2 Push [▼] or [▲] button to adjust the indoor unit number. The indoor unit number in the group control will
be changed cyclically. Select an indoor unit to change the settings and push [TIME] button to confirm.
The fan of the selected indoor unit starts its operation and the swing operation of the louvers starts after
confirmation.
(If [all] is displayed, directly push [TIME] button to enter the DN setting mode.)
CODE No. is displayed as [10] for the first time.
Step 3 Set the indoor unit type and capacity
(This data has been written to EEPROM at the factory by changing the type and capacity code.)
