Clearance of address (Return to status (Address undecided) at shipment from factory)
Method 1
An address is individually cleared from a wired remote controller.
"0099" is set up to line address, indoor address, and group address data from the wired remote controller.
(For the setup procedure, refer to the above-mentioned address setup from the wired remote controller.)
Method 2
Clear the indoor addresses in the same refrigerant line from the header unit.
1. Turn off the power of the refrigerant line to be returned to the status at shipment from factory, and change the
header unit to the following status.
1) Remove the relay connector between [U1U2] and [U3U4].
(If it has been already removed, leave it as it is.)
2) Turn on SW30-2 on the interface P.C. board of the header unit if it is ON.

executed.
