Home Page The main settings of the system are graphically summed up
on the Home Page.
The icon at top left indicates the type of regulation selected.
The icon at centre top indicates the operating mode selected
(auto or economy).
The icon at top right indicates the presence of a single or twin
inverter. The rotation of the icon or indicates which
circulation pump is operating.
At the centre of the Home Page is a read-only parameter which
can be chosen from a small set of parameters on Page 9.0 of
the menu.
From the Home Page it is possible to access the page for regu
-
lating the contrast of the display: hold down the hidden button,
then press and release the right button.
EVOPLUS circulators offer 2 menus: user menu and advanced
menu. The user menu is accessible from the Home Page by
pressing and releasing the central “Menu” button.
The user menu is accessible from the Home Page by holding
down the central “Menu” button for 5 seconds.
Page 1.0
The factory settings are set from Page 1.0 by holding down the
left and right buttons at the same time for 3 seconds.
The resetting of the factory settings will be notified by the ap
-
pearance of the symbol
next to the word “Default”.
Page 2.0
The regulating mode is set from Page 2.0. You can choose be
-
tween 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
Page 3.0
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 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 de-
pending on fluid te mperature.
Page 5.0
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
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: an-
alogue 0-10V (positive or negative increase) or PWM (positive
or negative increase).
