1. to 2. and 8. need to be performed.

Resetting the power after setting up all indoor units
Important:
• If the reset is not performed, function cannot be read correctly.
• After all the functions have been set, the circuit breaker needs to be switched off for at least 2
minutes.
– After the 2 minutes has passed, power can be restored.
– The set function is stored in the PCB and will remain in memory even when the power of in-
door unit is turned off.
However setting function is effective after disconnecting the power supply and then recon-
necting it.
• Record the latest configuration of the indoor unit function setting on a label, and put the label on
the unit so it can be used for after-sales service operations.
Once the RESET button is pressed on the remote controller, the operation mode will be set to the
AUTO MODE.
Adjust the operation mode to either cooling or heating before starting the operation of the air condi-
tioner.
NOTE:
If custom code other than " " is set, the remote control must be set accordingly to the in-
door unit setting.
