1-1. Test run procedure
NOTE
1) Auto. address operation decides each indoor unit address to the indoor unit connected to the refrigerant circuit
individually.
The required time of operation depends on the temperature.
It takes a maximum of 20 minutes for a link system.
It takes a maximum of about 3 minutes without turning on the compressor, for a system without link.
2) When linking outdoor units in a network (link system), Auto. address operation should be performed by each refriger-
ant circuit (outdoor unit) individually. If you start Auto. address operation of another refrigerant circuit during Auto.
address operation, the alarm message (E12) will be displayed.
3) Indoor unit address can be changed manually with the remote controller when required.
4) The selected indoor unit address is memorized in EEPROM even after power failure.
5) When using a system controller, zone registration is required after finishing the test run.
