If it is required to use a differential pressure
feedback, between delivery and suction of the pump
by using 2 transducers it's necessary to connect
the first transducer and the second transducer as
shown in section 6.7.

9.4.3. Automatic pump
frequency.
In this operating mode typically the pump runs
continuously without stop. If it is required to stop the
pump when it's working at the minimum operating
frequency (parameter SA03) it's necessary to
change the value of the parameter AP16 from "Off"
to "FM".
The system will restart when the temperature of the
system will reach the value of parameter tC02.
9.5. Constant flow operating mode.
Constant flow rate mode keeps constant the flow in
a point of the system.
This configuration uses a feedback given by a flow
sensor (connected as shown in section 6.7).
