Optional Accessories
1. W iring
Connect one end of the wiring to connector S21 of the PCB in the
indoor unit.
Connect the other end of the wiring to connector S6 of the adaptor
PCB.
Connect field wiring according to the functions assigned to each
connection terminal of the adaptor PCB.
Secure all wires.
1 Securing wires in the adaptor case assy (for KRP413A1S · KRP413AA1S)
Fasten with a tie-wrap so that wires will not come loose even if pulled.

Set SW1-1 to On and select Operation Mode 2.
Most settings (power On/Off, air flow rate, mode change) cannot be
made using the air conditioner's remote controller.
When power is restored after a power failure in this mode, On or Of f is
determined according to the current settings of the remote controller.
When the Cooling /Heating mode is changed, use the air conditioner's
remote controller to adjust the temperature.
