Address setting

On this unit, it is required to set the addresses of the indoor units before starting air conditioning.
Set the addresses following the steps below.
CAUTION
• Be sure to complete the electric wiring before setting the addresses.
• If you turn on the outdoor unit before turning on the indoor units, the CODE No. [E19] is indicated on the
7 - segment display on the interface P.C. board of the outdoor unit until the indoor units are turned on. This is not
a malfunction.
• It may take up to ten minutes (normally about five minutes) to address one refrigerant line automatically.
• Settings on the outdoor unit are required for automatic addressing. (Address setting is not started simply by
turning on the power.)
• Running the unit is not required for address setting.
Before setting the address, set the DIP-SW on the header outdoor unit interface P.C. board.
