-
Proportional differential pressure regulation depending on the flow present in the
plant.
-
Constant differential pressure regulation.
-
Regulation with constant curve.
The regulating mode may be set through the EVOPLUS SMALL control panel (see par.
10).
8.1.1.
Regulation with proportional differential pressure
In this regulating mode the differential pressure is reduced or
increased as the demand for water decreases or increases.
The Hs set point may be set from the display.
Regulation indicated for:
-
Heating and conditioning plants with high load losses
-
Two-pipe systems with thermostatic valves and head ≥ 4 m
-
Plants with secondary differential pressure regulator
-
Primary circuits with high load losses
-
Domestic water recirculating systems with thermostatic valves on the rising
columns.
8.1.2.
Regulation with Constant Differential Pressure
In this regulating mode the differential pressure is kept constant,
irrespective of the demand for water,
The Hs set point may be set from the display.
Regulation indicated for:
-
Heating and conditioning plants with low load losses
-
Two-pipe systems with thermostatic valves and head ≤ 2 m
-
Single-pipe systems with thermostatic valves
-
Plants with natural circulation
-
Primary circuits with low load losses

-
Domestic water recirculating systems with thermostatic valves on the rising
columns.
8.1.3.
Regulation with constant curve
In this regulating mode the circulator works on characteristic
curves at a constant speed. The operating curve is selected by
setting the rotation speed through a percentage factor. The
value 100% indicates the maximum limit curve. The actual
rotation speed may depend on the power and differential
pressure limits of your circulator model.
The rotation speed may be set from the display.
Regulation indicated for heating and conditioning plants with constant flow.

Expansion Modules
EVOPLUS SMALL circulators may be equipped with some expansion modules that
allow their functions to be increased. For details on the procedures for installation,
configuration and use of the expansion modules, see the specific manual.
9.
CONTROL PANEL
The functions of EVOPLUS SMALL circulators can be modified by means of the control
panel on the cover of the electronic control device. On the panel there are: a graphic
display, 4 navigation keys and 3 LED warning lights (see Figure 5).
9.1.
Graphic Display
Using the graphic display it will be possible to navigate in an easy and intuitive menu
which will enable you to check and modify the system operating mode, the enabling of
the inputs and the working set-point. It will also be possible to view the system status
and the log of any alarms memorised by the system.
9.2.
Navigation Buttons
4 buttons are provided for navigating in the menu: 3 buttons under the display and 1 at
the side. The buttons under the display are called active buttons and the one at the side
is called hidden button. Each page of the menu is made in such a way as to indicate
the function associated with the 3 active buttons (the ones under the display).
9.3.
Warning Lights
Yellow light: System live signal.
If lit, it means that the system is live.
