Check the rotary switch of the address of the
installed MCU to check any duplicate address.
Check the manual address
view in the view mode.
(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.
