[. . . ] Automatic address: Setup from SW15 on the interface P. C. board of the header unit It requires a maximum of 10 minutes (Usually, approx. 5 minutes) to set up automatically an address to 1 refrigerant line. To set up an address automatically, setup at the outdoor unit is necessary. (Address setup cannot be performed by power-ON only. ) 62 4-3-1 (1) Check at main power-ON After turning on the main power of the indoor units and outdoor units in the refrigerant system. Prior to starting test operation, check the following items in each outdoor and indoor unit. (After turning on the main power, be sure to check in order of indoor unit outdoor unit. ) Check on outdoor unit 1. Check that all the rotary switches, SW01, SW02 and SW03 on the interface P. C. board of the header outdoor unit are set to "1". If an error code is displayed on 7-segment [B], remove the cause of the fault . Check that [L08] is displayed on the 7-segment display [B] on the interface P. C. (OK when display goes on. ) Group address (Group address) Individual : 0000 Header unit : 0001 Follower unit : 0002 8 9 10 11 In case of group control Using the code. buttons, set on the item Operation procedure Using the buttons, set Individual = , Header unit = , Follower unit = Push the button.
