●Change by the jumper wire

	Name		Function
J1 (SW7-1)		With	Input signal - Reverse invalid
		None (1)	Input signal - Rus stop
J2 (SW7-2)		With	Heating thermostat OFF-Lo
		None (1)	Heating thermostat OFF-Stop, Lo
J3 (SW7-3)		With	Normal operation operable
		None (1)	Operation permission prohibited
J4 (SW7-4)		With	Normal
		None (1)	Heating temp. +3
J5 (SW8-1)		With	Louver free stop control - Invalid
		None (1)	Louver free stop control - Effective
J6 (SW8-2)		With	Freeze prevention fan control activated.
		None (1)	Freeze prevention fan control deactivated.
J8 (SW8-4)		With	Model 151~251
		None (1)	Model 301

Note (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 jumpers J1 ~ J8. Instead, SW7 and 8, with the same functions as jumpers J1~J8, are used in the position where the jumpers were previously. Set SW7 and 8 locally in accordance with the above table.

●Control change switch (SW5, SW9, SW10)
