unit individually by each remote controller, P.C. boards of remote controller must be modified according to the indoor unit
number.

The P.C. board has the print “J1” and “J2”. Jumper wires are mounted to each “J1” and “J2”.Cut “J1” and “J2” according to
the number of indoor unit as shown in Table 1.
After modification, push the RESET. button near the MIN-button on the remote controller.

remote controller number is designated as the indoor unit number. Therefore at and after the second
time indoor unit accepts the remote controller of the initial setting number.
At setting - error, turn the power supply off to cancel the individual operation and then turn the power
supply on to restart the setting.
