Check the machine where the error

- If SEG1 is C, MCU.
Find a unit whose address is duplicated in the
manual address view on the view mode of the
outdoor unit display. (If there is an address that
does not appear in the manual address view even
though a unit is actually installed, the address is
duplicated.)

(Press and hold K4 switch to enter)
※ K3 reset
When the system is reset through K3 reset, the previous error
(E108) on the display is sometimes indicated. This indicates
the error left previously in the indoor unit during the course
of performing resetting and addressing the whole system
after the outdoor unit is reset. When addressing is completed,
the error indication disappears (up to 5 minutes required).
※ Whole system power reset
- To solve the problem through the power reset after
the address is reset the power reset of individual units
is meaningless and the power of the whole system
must be reset.
