Wiring
1. Wiring
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.

If the wire protrudes from
this side, cut the cut-off
section of the case front.
2
Securing wires in the indoor unit (for KRP413A1)
The method for securing wire varies depending on the model of the air
conditioner. See your air conditioner installation manual for details.
2. Automatic Reset After Power Failure
This PCB stores the following data in the event of a power failure
(common features).

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 Off 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.

The remote controller most
recently used (local or air
conditioner) takes precedence.
Use a remote controller with a
pulse width of 100 msec or
more.
Power On/Off cannot be controlled
from the unit’s remote controller.
When power is restored after a
power failure in this mode, On or
Off is determined according to
the current settings of the remote
controller.
