n Indoor unit power-ON sequence

• In a group operation, if the indoor unit which was fed power after judgment of automatic address cannot

receive regular communication from the header unit and regular communication on identical pipe within

120 seconds after power was turned on, it reboots (system reset).
→ The operation starts from judgment of automatic address (Gr construction check) again.

(If the address of the header unit was determined in the previous time, the power fed to the header unit

and reboot works, the header unit may change though the indoor unit line address is not changed.)
