System-wide functions

Function	WE	Configuration
Return flow sensor RüF1, 2, 3	OFF	Co1, 2, 3	-> Fb01 = ON
	1.0	Limitation factor / 0 to 25.5
Parameters	WE	Parameter level / Range of values
Max. return flow temperature	65 °C	PA1, 2, 3	/ 20 to 90 °C
Min. return flow temperature	20 °C	PA1, 2, 3	/ 20 to 90 °C

In systems with a DHW in a secondary circuit, the control during DHW heating uses the Return flow limitation temperature for DHW parameter (systems Anl 2, 4, 5 and 10). In the transition time or in summer mode, the heating circuit can be operated with a lower return flow tempera- ture while at the same time performing proper storage tank charging.

The Return flow limitation temperature for DHW parameter can also be active in systems Anl 4, 5, 7, 8, 9 and 10 at a separate return flow sensor. The separate sensor RüFTW (return flow sen- sor for DHW) must in this case be installed in the return flow of the DHW circuit.

Note!

In system Anl 2 , the sensor RüFprim is installed in the return flow of the primary circuit. In this case, the Return flow sensor, primary function must be activated (Co5 -> Fb01 = ON).

Function	WE	Configuration
Return flow sensor in DHW circuit	OFF	Co4 -> Fb02 = ON
	1.0	Limitation factor / 0 to 25.5
Parameter	WE	Parameter level / Range of values
Return flow limitation temperature for DHW	45 °C	PA4 / 20 to 90 °C

Note!

To ensure that the preset return flow temperature limit can be met, make sure that

–the heating characteristic is not adjusted to ascend too steeply,

–the speed of the circulation pumps is not set too high,

–the heating systems have been calibrated.
