Turn the power on. Green On/Off light will flash.2. Set the system to operate using the remote controller. Green On/Off light will be on constantly.3. Press and hold down the temporary button for three seconds.4. The indoor unit will bleep three times to acknowledge set up. In most cases the green light changes to orange.5. The system will continue to operate during this set up.6. After set up the system may be stopped using the remote controller.To cancel auto restart:1. The system is operating. Green On/Off light will be on constantly.2. Stop the system operating using the remote controller. Green On/Off light will extinguish.3. Press and hold down the temporary button for three seconds.4. The indoor unit will bleep three times to acknowledge cancellation.5. The system will have stopped operating.This feature cannot be set if the timer is in operation.The louver will not swing, if it was previously set, when the system auto restarts.Page 8 of 72

AI Central Controller - Zone AddressRBC-CR1-PE and RBC-CR64-PEIf a standard remote controller has not been installed the Zone Addresses may be set using dip switches onthe indoor printed circuit boards. This dip switch is identified as “LAN ADDRESS” and “SW02”, it is a seven-bit switchlocated centrally on the PCB.Procedure1. Turn off the power2. Put ‘Bit 7’ of switch SW02 to the on position, this blocks a zone address set using a std remote controller.3. Set zone address number by using ON/OFF combinations of ‘Bits 1 6’ of switch SW02.4.
