Indoor units to have their addresses initialized
Resetting the Address (Resetting to the Factory Default (Address Undecided))
Method 1
Clearing each address separately using a wired remote controller.
Set the system address, indoor unit address and group address to “
0099 ” using a wired remote controller.
(For the setting procedure, refer to the address setting procedures using the wired remote controller on the previous pages.)
Method 2
Clearing all the indoor unit addresses on a refrigerant line at once from the outdoor unit.
1
Turn off the refrigerant line to reset to the factory default and set the header outdoor unit of the line as below.
1) Disconnect the relay connectors between the [ U1 , U2 ] and [ U3 , U4 ] terminals.
(Leave them as they are if they have already been disconnected.)
2) Turn on dip switch 2 of SW30 on the interface P.C. board of the header outdoor unit if the switch is OFF.
(Leave it as it is if it has already been set to ON.)
3
Confirm that the 7-segment display indicates “A.d. c.L.” and set SW01, SW02 and SW03 to 1, 1, 1
respectively.
4
After a time “ U.1.L08 ” appears on the 7-segment display if the address clearing has been completed
successfully. If the 7-segment display indicates “A.d. n.G.”, the outdoor unit may still connected with
other refrigerant lines. Check the connection of the relay connectors between [ U1, U2 ] and [ U3, U4 ].
NOTE
Take care to carry out the procedure above correctly; otherwise, addresses in other refrigerate lines may also be
cleared.
5
Set the addresses again after finishing the clearance.
2
Turn on the indoor and outdoor units of the refrigerant line for which you want to initialize the addresses.
About one minute after turning on the power, confirm that the 7-segment display on the header outdoor
unit indicates “ U.1. - - - ” and operate the interface P.C. board on the header outdoor unit of the refrigerant
line as follows.
