On Page 4.0 it is possible to modify the parameter THs with
which to make the curve depending on temperature (see
Par. 8.1.4).
This page will be displayed only for the regulating modes
depending on fluid te mperature.
Page 5.0 allows you to set the "auto" or "economy"
operating mode.
"Auto" mode disables the reading of the status of digital
input IN2 and in fact the system always activates the set-
point set by the user.
"Economy" mode enables the reading of the status of
digital input IN2. When input IN2 is energised the system
activates a percentage reduction of the set-point set by the
user (Page 6.0 of the EVOPLUS menu).
For the connection of the inputs see par. 6.2.1
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 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.

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
