10. ADDRESS SETUP
10-1. Address Setup
<Address setup procedure>
When an outdoor unit and an indoor unit are connected and they are twin-triple, or when an outdoor unit is
connected to each indoor unit respectively in the group operation even if multiple refrigerant lines are provided,
the automatic address setup completes with power-ON of the outdoor unit. The operation of the remote
controller is not accepted while automatic address works. (Approx. 4 to 5 minutes)
• When the following addresses are not stored in the neutral memory (IC10) on the indoor P.C. board, a test
run operation cannot be performed. (Unfixed data at shipment from factory)
