Page 6.0
Page 6.0 is displayed if "economy" mode has been
chosen on page 5.0 and allows setting of the percentage
value of the set-point.
This reduction will be carried out if digital input IN2 is
energised.
Page 7.0
Page 7.0 is displayed if an operating mode has been
chosen with set-point regulated by an external signal.
This page allows you to choose the type of control signal:
analogue 0-10V (positive or negative increase) or PWM
(positive or negative increase).
Page 8.0
If a twin system is used (see Par. 6.3) on page 8.0 you
can set one of the 3 possible twin operation modes:
Alternate every 24h: The 2 circulators
alternate in regulation every 24 operating hours. If one of
the 2 malfunctions, the other takes over regulation.
Simultaneous: The 2 circulators work at the
same time and at the same speed. This mode is useful
when a flow rate is required that cannot be provided by a
single pump.
Main/Reserve: Regulation is always
performed by the same circulator (Main), the other
(Reserve) takes over only if there is a malfunction of the
Main one.
If the twin communication cable is disconnected the
systems automatically figure as Single, working
completely independent of each other.
Page 9.0
On page 9.0 it is possible to choose the parameter to be
displayed on the Home Page:
H: Measured head expressed in metres
Q: Estimated flow rate expressed in m3/h
S: Rotation speed expressed in revs per minute (rpm)
E: Head requested by external signal 0-10V or PWM, if
active
P: Power distributed expressed in kW
h: Operating hours
T: Liquid temperature measured with the sensor fitted on
board

On page 10.0 you can choose the language in which to
display the messages.
Page 11.0
On page 11.0 you can display the alarms log by pressing
the right button.
Alarms Log
If the system finds any faults it records them permanently
in the alarms log (up to a maximum of 15 alarms). For
each recorded alarm a page composed of 3 parts is
displayed: an alphanumeric code that identifies the type
of fault, a symbol that illustrates the fault in graphic mode,
and a message in the language selected on Page 10.0,
giving a brief description of the fault.
By pressing the right button you can scroll through all the
pages of the log.
2 questions appear at the end of the log:
"Reset Alarms?"
Pressing OK (left button) resets any alarms still present
in the system.
