●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.

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 ~ J6. Instead, SW7 and 8, with the same functions as jumpers J1~J6, 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)

Function of DIP switch SW5 (Usually all turned OFF)

	Switch			Function
	ON		ON	Setting time : 1000hrs. (Unit stop)
SW5-3		SW5-4	OFF	Setting time : 1000hrs. (Display)
	OFF		ON	Setting time : 600hrs. (Display)
			OFF	Setting time : 180hrs. (when shipped from factory)

Function of DIP switch SW9 (Usually all turned OFF)

	Switch		Function
SW9-3		ON	Emergency operation
		OFF	Normal
SW9-4		ON	Fan control : Powerful mode
		OFF	Fan control : Mild mode

Note (1) It is normally ON only in the case of SW9-4.

Function of DIP switch SW10 (Usually all turned OFF)

	Switch				Function
