FB	Function	WE	Anl	Comments
9	Parallel pump	OFF	2, 3,	FB9 = ON: Parallel pump operation
	operation		9	Select (Anl 2 and 9):
				PU: Parallel pump operation
				US: Operation with switchover valve
				Function block parameter (on selecting: US):
				Stop parallel oper. in case of deviation / 2 to 10 min (10 min)
				FB9 = OFF: Intermediate heating after 20 min
				Select (FB9 = ON, US or FB9 = OFF):
				20: Intermediate heating after 20 min
				– –: No intermediate heating
10	Control mode	ON	All	FB10 = ON: Three-step signal control mode
	three-step RK1			Function block parameters:
				KP (proportional gain) / 0,1 to 50 (0,5)
				TN (reset time) / 1 to 999 s (200 s)
				TY (valve transit time) / 15, 30, 45 to 240 s (90 s)
				Pump lag time / 1 x TY to 10 x TY (2 x TY)
				FB10 = OFF: On/off control; when FB10 = OFF also FB11 = OFF
				Function block parameter:
				Hysteresis / 1 to 30 °C (5 °C)
11	Limit deviation for	OFF	All	FB11 = ON, only when FB10 = ON: Limitation active
	OPEN signal RK1			Function block parameter:
				Max. deviation / 2 to 10 °C (2 °C)
12	Limit deviation for	OFF	4	FB12 = ON, only when FB17 = ON: Limitation active
	OPEN signal RK2		to	Function block parameter:
			11	Max. deviation / 2 to 10 °C (2 °C)
13	Room sensor RF	OFF	All	FB13 = ON: Sensor/remote operation activated
				Cannot be selected when FB0, FB1 or FB2 = ON;
				when FB0, FB1 and FB2 = OFF the room temperature is only
				indicated and not used for the control
14	Storage tank sensor	ON	2, 3,	FB14 = ON: Sensor SF1 activated
	SF1		5, 7,	Storage tank thermostat: FB14 = FB15 = OFF
			8, 9,
