9.4.3. Automatic pump stop at minimum
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 ow operating mode.
Constant ow rate mode keeps constant the ow in
a point of the system.
This conguration uses a feedback given by a ow
sensor (connected as shown in section 6.7).

9.6. Fixed speed operating mode.
In this mode the system works as a traditional

To allow which the system works properly,
the operating frequency is limited between
parameter SA03 (minimum operating
frequency) and parameter UP03 (nominal
frequency of the pump).
9.6.2. Fixed speed operation by an external
reference.
If it is necessary to control the frequency from an
external unit it is required to make the connection
as described in section 6.8.

The maximum frequency (parameter UP03) will
be related to the maximum value of the external

9.7. Night mode
Night mode is an optional operating mode which
reduces the frequency of the system when the
temperature is below a certain value.
This option use a feedback of a temperature
transducer connected as described in section 6.7.
(secondary transducer electrical connection).
Because on I-MAT only two analog inputs
are available, this option does not allow
other options or operating modes which
need 2 transducers (i.e. differential mode).
