The regulating mode is set from Page 2.0. You can choose
between the following modes:
1 = Proportional differential pressure regulation.
2 = Proportional differential pressure regulation with set-
point set by external signal (0-10V or PWM).
3 = Proportional differential pressure regulation with set-
point depending on temperature.
4 = Regulation with constant differential pressure.
5 = Constant differential pressure regulation with set-point
set by external signal (0-10V or PWM).
6 = Constant differential pressure regulation with set-point
depending on temperature.
7 = Regulation with constant curve with rotation speed set
from the display.
8 = Regulation with constant curve with rotation speed set
by an external signal (0-10V or PWM).
Page 2.0 displays 3 icons which represent:
- central icon = setting currently selected
- right icon = next setting
- left icon = previous setting

Depending on the type of regulation chosen on the previous
page, the set-point to be set will be a head or, in the case of a
Constant Curve, a percentage of the rotation speed.

On Page 4.0 it is possible to modify the parameter THs with
which to make the curve depending on temperature (see Par.
10.1.4).
This page will be displayed only for the regulating modes de-

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. 8.2.1
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 ener-
gised.
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: ana-
logue 0-10V (positive or negative increase) or PWM (positive
or negative increase).

If a twin system is used (see Par. 8.3) on page 8.0 you can set one
of the 3 possible twin operation modes:
Alternate every 24h:
The 2 circulators alternate in regula-
tion every 24 operating hours. If one of the 2 malfunctions,
the other takes over regulation.
Simultaneous:
The 2 circulators work at the same time

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 auto-
