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.

The regulating mode is set from Page 2.0. It is possible to choose from 3 different
modes:
1. = Regulation with constant differential pressure
2. = Regulation with constant curve with speed set from the display.
3. = Regulation with constant curve with speed set by remote signal 0-
10V.
4. = Proportional differential pressure regulation.
Page 2.0 displays the three icons which represent:

central icon = setting currently selected

Page 3.0
The regulating set-point is set 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 (
Hs ) or a frequency ( Fs ).
Page 4.0
Page 4.0 is displayed only if a regulating mode with set-point according to
temperature has been selected
(if available), and it allows setting of the Tmax.
(50°C or 80°C) with which to set the temperature dependence.
Page 5.0 Page 5.0 is displayed in all pressure regulating modes and allows the setting of
“auto” or “economy” operating mode.
“Auto” mode disables the reading of the status of digital input I2 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 I2. When input I2
is energised the system activates a percentage reduction of the set-point set by the
user (Page 6.0).
For the connection of the inputs see par. 5.5.1
