The regulating set-point can be modified from Page 3.0.
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.
Page 4.0
On Page 4.0 it is possible to modify the parameter Tmax with which to make
the curve depending on temperature (see Par. 10.1.4).
This page will be displayed only for the regulating modes depending on fluid
temperature.
Page 5.0 allows you to set the "auto" or "economy" operating mode.
Page 5.0
"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 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).
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:
If the twin communication cable is disconnected the systems automatically figure as
Single, working completely independent of each other.
ENGLISH
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.
