		value
	BYTE		DI_NOT_USED	This configuration variable specifies the digital input function and type
	DI_WINDOW_CLOSED	0		of switch. The option to be selected is the one which is the condition for
	DI_OCCUPIED_SENSOR	1		a closed switch contact (e.g., normally-closed window switch contact =
	DI_AIR_FLOW	2		DI_WINDOW_CLOSED, normally-open window switch contact =
	DI_CHANGEOVER_COOL	3		DI_WINDOW_OPEN).
	DI_WINDOW_OPEN	4		DI_MOVEMENT and DI_NO_MOVEMENT are supported starting with
	DI_UNOCCUPIED_SENS	5		DI_MOVEMENT and DI_NO_MOVEMENT are supported starting with
	DI_NO_AIR_FLOW	6		FCU2 version 1.0.3. These configuration settings cause the controller
	DI_CHANGEOVER_HEAT	7		to retain the occupied state for 15 minutes after the last movement is
	DI_MOVEMENT	8		detected.
	DI_NO_MOVEMENT	9
	DI_NOT_USED	255

	BYTE		THREE_SPEED	This configuration variable specifies the type of fan connected to the
	NO_FAN	0		controller.
	ONE_SPEED	1
	TWO_SPEED	2
	THREE_SPEED	3

	BYTE		OUTP_HEATING	This configuration variable specifies the operating mode of the output
	OUTP_COOLING	0		1.
	OUTP_HEATING	1
	OUTP_CHANGEOVER	2
	OUTP_NOT_USED	255

	BYTE		OUTP_COOLING	This configuration variable specifies the operating mode of the output
	OUTP_COOLING	0		2. This setting is ignored for nciNumValve = TWO_PIPE.
	OUTP_HEATING	1
	OUTP_CHANGEOVER	2
	OUTP_NOT_USED	255
