●Change by the jumper wire

Switch		Function
J1	with	1 Phase
(SW4-1)	None(1)	3 Phase
J2	with	Cooling
(SW4-2)	None(1)	Heating
J6	with	Defrost recovery temperature 14ºC
(SW6-2)	None(1)	Defrost recovery temperature (See page 88)
J7	with	Defrost prohibited temperature 45 min.
(SW6-3)	None(1)	Defrost prohibited temperature 37 min.
J8	None(1)	-
(SW6-4)

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

(2)The replacement board is not equipped with jumper wires JA1~JA8. Instead, SW4 and 6 are mounted in the same position and have the same functions as jumper wires JA1~JA8. Carry out the local settings in accordance with the above table using SW4 and 6.

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

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

●Overcurrent Setting

Model	301HEN	301HES	401HEN	401HES	501HES	601HES
Setting Value (A)	17	10	27	11	12	14
J11 (SW3-1)	With	With	With	With	With	With
J12 (SW3-2)	None(1)	None(1)	None(1)	None(1)	With	With
J13 (SW3-3)	None(1)	None(1)	With	With	None(1)	With

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

(2)The replacement board is not equipped with jumper wires J11~J13. Instead, SW3 is mounted in the same position and has the same func- tions as jumper wires J11~J13. Carry out the local settings in accor- dance with the above table using SW3.

(3)The overcurrent setting value becomes the above setting value (A) automatically in accordance with the settings on J11(SW3-1) ~ J13(SW3-3) and J1(SW4-1).
