You will be prompted to enter a code number when you select one of the following function
blocks !
20 Return flow sensor
RüF
(See chapter 4.8)
ON When FB 20 = ON, the return flow sensor RüF is
activated. Set the limitation factor, setting range
0.1 to 10 (default: 1). In Anl2, you can select
afterwards between "SLP" (default) – SLP
activated depending on return flow temperature
with drinking water demand and deactivated
heating circuit – and "– –" – immediate
activation of SLP with drinking water demand
and deactivated heating circuit.

In Anl4.0 when RüF2 is activated, set the
limitation factor = 0.1 to 10 (default: 1); In Anl 5
FB 21 can only be activated when FB 20 = ON. It
is only appropriate when the return flow sensor
RüF1 is installed in the common return flow pipe.
FB 21 is automatically deactivated and cannot
be activated when FB 20 = OFF
22 Signal input for
flow rate
measurement
(See chapter 4.15)
OFF When FB 22 = ON, the signal input is defined
for flow rate measurement.
Furthermore, you can select between 0 or 4 to
20 mA signal connection. This function can only
be activated with FB23!
Connect a 50 Ohm resistance to terminals 12 (+)
and GND (terminals 5 to 8) parallel to signal!
When FB 22 = OFF, the pulse input is defined for
limitation. This function can only be activated
with FB23!
23 Limitation of
capacity or
flow rate
(See chapter 4.15)
OFF When FB 23 = ON and FB 22 = OFF, the pulse
rate limitation is activated.
You must then set the limit value for heating, its
associated limitation factor and, if needed, the
limit value for drinking water heating and its
associated limitation factor. Respective setting
ranges 3 to 500 pulse/hr and 0.1 to 10!
When FB 23 = ON and FB 22 = ON, the flow
rate limitation via current signal is activated.
You must determine upper measuring range
value – setting range 0.1 to 100 m
3
/hr –,
the flow rate’s minimum limit value and
maximum limit value
– Setting ranges for both 0.01 to 100 m
