17 - OUTDOOR/INDOOR UNIT REFRIGERANT CIRCUIT ADDRESS

Indoor units that are part of a multisplit system must be properly configured to be able to communicate with the

outdoor unit over different channels (Indoor A, Indoor B, etc...) of the communication bus.

Each indoor unit address must correspond to the physical connection of the indoor unit to the outdoor unit refrigerant

circuit, i.e.:

Refrigerant Circuit A <--> Indoor Unit Address A

Refrigerant Circuit B <--> Indoor Unit Address B

(1) Dip-switch setting: the address is set by mean of a dip-switch located on the indoor unit pcb.

(2) Remote controller procedure: the address is set by mean of a special setting on the remote controller.

(3) Automatic addressing procedure: the address is automatically set on every indoor unit of the system by mean of

an automatic procedure.
