●Change by the jumper wire

Model	151	201	251
JA1 (SW7-1)	None	None	None
JA5 (SW6-1)	None	None	None
JA6 (SW6-2)	None	With	None
JA7 (SW6-3)	None	None	With
JA8 (SW6-4)	With	With	With

Notes (1) “None” means that jumper wire is not provided on the PCB or the connection is cut

(2)The replacement PCB is not equipped with jumper wires JA1 and JA5~JA8. Instead, SW6 and 7 are mounted in the same position and have the same functions as jumper wires JA1 and JA5~JA8. Carry out the local settings in accordance with the table using SW6 and 7.

●Function of DIP switches (SW5) (Usually all turned OFF)

	Switch		Function
	SW5-1	ON	Defrost Setting Select For cold regions.
	SW5-1	OFF	Normal
		OFF	Normal
	SW5-2	ON	Snow-guard fan control-Effective
	SW5-2	OFF	Snow-guard fan control-Invalid
	SW5-3	ON	Low refrigerant protection control-Effective
	SW5-3	OFF	Low refrigerant protection control-Invalid
		OFF	Low refrigerant protection control-Invalid
	SW5-4	ON	Test run operation-Heating
	SW5-4	OFF	Test run operation-Cooling
		OFF	Test run operation-Cooling

●Change by the JA3

Switch		Function
JA3	with	Model selection-Energy saving
(SW7-3)	None	Model selection-Standerd

Note (1) “None” means that jumper wire is not provided on the PCB or the connection is cut.
