FB	Function	WE	Anl	Comments
16	Sensor selection	OFF	All	FB16 = ON; select: P1000: Pt 1000 and Pt 100 sensors*
				ntc:	NTC and Pt 100 sensors*
				FB16 = OFF: PTC and Pt 100 sensors*
				* A mixture of both types of sensor is possible
17	Control mode	ON	4, 5,	FB17 = ON: Three-step signal control mode
	three-step RK2		6, 7,	Function block parameters:
			8, 9,	KP (proportional gain) / 0.1 to 50 (0,5)
			11	TN (reset time) / 1 to 999 s (Anl 5, 6: 60 s; Anl 4: 200 s)
				TY (val. transit time) / 15, 30 to 240 s (Anl 5, 6: 30 s; Anl 4: 90 s)
				FB17 = OFF: On/off control
				Function block parameter:
				Hysteresis / 1 to 30 °C (5 °C)
18	Outdoor	OFF	All	FB18 = ON: Current input to measure outdoor temperature
	temperature –			activated
	current input			Select: 0: 0 to 20 mA = –20 to 50 °C
				4: 4 to 20 mA = –20 to 50 °C
				A 50-Ωresistor must be connected to terminals 7 (+) and GND
				(terminals ½) in parallel to the current signal
				FB18 = OFF: Sensor input for measuring outdoor temperature
19	4-point	OFF		FB19 = ON: Characteristic according to four points
	characteristic			FB19 = OFF: Characteristic according to gradient
20	Return flow sensor	ON	All	FB20 = ON: Return flow sensor activated
	RüF1			Function block parameter:
				Limiting factor / 0.1 to 10 (1)
				Selection with systems Anl 2, 7 and 9:
				SLP (thermometer and heat exchanger icons) switched on de-
				pending on return flow temperature or SLP switched on irrele-
				vant of return flow temperature
				Setting only possible after entering key number!
21	Return flow sensor	OFF	4, 5,	FB21 = ON: Return flow sensor RüF2 activated
	RüF2		11	Function block parameter:
				Limiting factor / 0,1 to 10 (1)
				Selection with system Anl 5:
				SLP (thermometer and heat exchanger icons) switched on de-
				pending on return flow temperature or SLP switched on irrele-
				vant of return flow temperature
				Setting only possible after entering key number!
