Manual address setup from remote controller

In case to decide an address of the indoor unit prior to finish of indoor wiring work and unpracticed outdoor wiring work (Manual setup from remote controller)

• Remain only SW30-2 of the header outdoor unit with address

1 as ON. (With end terminal resistance)

SW30

Arrange one indoor unit and one remote controller set to 1 by 1.

1 Push simultaneously SET + CL + TEST buttons for 4 seconds or more.

•Set up SW30-2 of the other header outdoor units to OFF. (Without terminal resistance)

9.Connect the relay connector between [U1, U2] and [U3, U4] of the header unit for each refrigerant line.

10.Then set up the central control address.

(For the central control address setup, refer to the Installation manual of the central control devices.)
