1. PARTICULAR WARNINGS
Ensure that the product has not suffered any damage during transport
or storage. Check that the outer casing is unbroken and in excellent
conditions.
Always switch off the mains power supply before working on the electri-
cal or mechanical part of the system. Wait for the warning lights on the
control panel to go out before opening the appliance. The capacitor of
the direct current intermediate circuit remains charged with dangerously
high voltage even after the mains power has been turned off.
Only rmly cabled mains connections are admissible. The appliance
must be earthed (IEC 536 class 1, NEC and other applicable standards).
Mains terminals and motor terminals may still have dangerous voltage
when the motor is stopped.
If the power cable is damaged, it must be replaced by the technical assis-
tance service or by qualied personnel, so as to avoid any risk.
2. PUMPED LIQUIDS
The machine has been designed and made for pumping water, free from explosive sub-
stances and solid particles or bres, with a density of 1000 Kg/m³, a kinematic viscosity
of1mm²/sand non chemically aggressive liquids. It is possible to use ethylene glycol in a
percentage of no more than 30%.
3. ELECTROMAGNETIC COMPATIBILITY (EMC)
EVOPLUS circulators respect standard EN 61800-3, in the C2 category, for electromag-
netic compatibility.
-Electromagnetic emissions - Industrial environment (in some cases restrictive
measures may be requested).
-Conducted emissions - Industrial environment (in some cases restrictive meas-
ures may be requested).
4. MANAGEMENT
4.1 Storage
All the circulators must be stored in a dry covered place, with possibly constant air hu-
midity, free from vibrations and dust. They are supplied in their original pack in which
they must remain until the time of installation. If this is not the case, accurately close the
suction and delivery mouth.
4.2 Transport
Avoid subjecting the products to needless impacts and collisions. To lift and transport the
circulator use lifting devices with the aid of the pallet supplied with it (if contemplated).
4.3 Weight
The adhesive plate on the packaging indicates the total weight of the circulator.
5. INSTALLATION
Carefully follow the advice in this chapter to carry out correct electrical, hydraulic and
mechanical installation.
Ensure that the voltage and frequency on the data plate of the EVOPLUS
circulator are the same as those of the power mains.
5.1 Circular Installation and Maintenance
Always install the EVOPLUS circulator with the motor shaft in a horizon-
tal position.Install the electronic control device in a vertical position (see
Figure 1)
- Thecirculatormay be installed in heating and conditioning systems on either the deliv-
ery pipe or the return pipe; the arrow marked on the pump body indicates the direction
of ow.
-Install the circulator as far as possible above the minimum boiler level and as far as
possible from bends, elbows and junction boxes.
-To facilitate control and maintenance operations, install an interception valve both on
the suction pipe and on the delivery pipe.
-Before installing the circulator, accurately ush the system with only water at 80°C.
Then drain the system completely to eliminate any harmful substance that may have
got into circulation.
-Assembleinsuchawayasto avoid dripping on the motor and on the electronic control
device during both installation and maintenance.
-Avoid mixing additives derived from hydrocarbons and aromatic products with the cir-
culating water. It is recommended that the addition of antifreeze, where necessary,
should not exceed 30%.
-In the event of heat insulation use the special kit (if provided) and ensure that the con-
densate draining holes in the motor casing are not closed or partly blocked.
-To guarantee maximum efciency of the system and long life of the circulator it is
recommended to use magnetic sludge-removing lters to separate and collect any im-
purities present in the system (particles of sand, particles of iron and sludge)

ENGLISH GB
14
Never insulate the electronic control device.
- In the case of maintenance, always use a set of new gaskets.
5.2 Rotation of the Motor Heads
If the circulator is installed on pipes in a horizontal position, it will be necessary to rotate
the motor with the respective electronic device through 90 degrees in order to maintain
the grade of IP protection and to allow the user a more convenient interaction with the
graphic interface (see Figure 2-3).
Before rotating the circulator, ensure that it has been completely drained.
Should it be necessary to rotate the motor heads, follow the instructions below with care
to ensure correct installation:
1. Unscrew the 4 screws xing the motor assembly to the pump body (gure A).
2. Rotate the motor assembly keeping it in the seat where it couples with the pump
body (gure A-B).
3. Once the head has been rotated into the desired position, tighten the 4 screws,
always proceeding in cross formation (gure C).
If the motor assembly has been removed from its seat, pay the greatest attention during
assembly, taking care to insert the impeller completely in the oating ring before tighten-
ing the retaining screws (gure D). If it has been correctly assembled, the motor assembly
rests completely on the pump body.
Incorrect assembly may damage the impeller, causing a typical rubbing
noise when the circulator starts.
The electronic control device must always remain in vertical position!
Ensure that the connecting cable of the pressure sensor never comes in
contact with the motor casing.
5.3 Non-return valve
If the system is equipped with a non-return valve, ensure that the minimum pressure of
the circulator is always higher than the valve closing pressure.
6. ELECTRICAL CONNECTIONS
The electrical connections must be made by expert, qualied personnel.
-The circulator does not require any external motor protection.
-Ensure that the supply voltage and frequency are the same as the values indicated on
the electrical data plate of the circulator.

Closed Closed Pump running with reduced set-point
6.2.2 MODBUS and LON Bus
EVOPLUS circulators provide serial communication through an input RS-485. The com-
munication is realised according to MODBUS specications.
With MODBUS it is possible to set the circulator operating parameters in remote mode
such as, for example, the desired differential pressure, the inuence of temperature, the
regulating mode, etc. At the same time the circulator can provide important information
on the system status.
For the electrical connections refer to Figure 6 and to Table 3:
MODBUS Terminals Terminal no. Description
A 2 Terminal not inverted (+)
B 1 Terminal inverted (-)
Y 3 GND
Table 2: Digital inputs IN1 and IN2
Table 3: RS_485 MODBUS terminals

ENGLISH GB
16
The MODBUS communication conguration parameters are available in the advanced
menu see Par.10). EVOPLUS circulators also have the possibility of communicating on
LON bus through external interface devices.
Further information and details on the MODBUS and LON bus interface are available at
the following link: http://www.dabpumps.com/evoplus
6.2.3 Analogue Input and PWM
Figure 8 shows the wiring diagram of the external signals 0-10V and PWM. As may be
seen from the gure the 2 signals share the same terminals on the terminal board, so they
are mutually exclusive. If you want to use an analogue control signal, you will have to set
the type of signal from the menu (see par. 10).

umns
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 or by an external
signal 0-10V or PWM.
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 col-
umns.
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 circu-
lator model.
The rotation speed may be set from the display or by an external
signal 0-10V or PWM.
Regulation indicated for heating and conditioning plants with constant ow.
8.1.4 Regulation with Constant and Proportional Differential Pressure depending
on the Water Temperature In this regulating mode the regulating set point
Hs is reduced or increased according to the wa-
ter temperature. THs may be set from 0ºC to 100
ºC in order to allow operation in both heating and
conditioning plants.

As well as being at a high temperature and pressure, the uid in the sys-
tem may also be in the form of steam. DANGER OF SCALDING!
It is dangerous to touch the circulator. DANGER OF SCALDING!
Once all the electrical and hydraulic connections have been made, ll the system with
water and if necessary with glycol (for the maximum glycol percentage see par. 2) and
feed the system. Once the system has been started it is possible to modify the operating
modes to adapt better to the plant requirements (see par.10).
8. FUNCTIONS

-Plants with variable ow (two-pipe heating
plants), where a further reduction of the circu-
lator performance is ensured depending on the
lowering of the temperature of the circulating liq-
uid, when the demand for heating is lower.
-Plants with constant ow (single-pipe and under-
oor heating plants), where the circulator perfor-
mance can be regulated only by activating the
temperature inuence function.
9. CONTROL PANEL
The functions of EVOPLUS circulators can be modied by means of the control panel on
the cover of the electronic control device.

pending on uid 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).

Alarms Log If the system nds any faults it records them permanently in the
alarms log (up to a maximum of 15 alarms). For each recorded
alarm a page composed of 3 parts is displayed: an alphanumer-
ic code that identies the type of fault, a symbol that illustrates
the fault in graphic mode, and a message in the language se-
lected on Page 10.0, giving a brief description of the fault.
By pressing the right button you can scroll through all the pages
of the log.
2 questions appear at the end of the log:
“Reset Alarms?”
Pressing OK (left button) resets any alarms still present in the
system.
“Delete Alarms Log?”
Pressing OK (left button) deletes the alarms memorised in the
log.
Pagina 12.0 On page 12.0 you can set the system status in ON, OFF or
controlled by a remote signal EXT (digital input IN1).
If ON is selected the pump is always on.
If OFF is selected the pump is always o󰀨.
If EXT is selected, reading of the status of digital input IN1 is
enabled. When input IN1 is energised the system goes ON and
the pump is started (on the Home Page the messages “EXT”
and “ON” appear alternately at bottom right); when input IN1 is
not energised the system goes OFF and the pump goes o󰀨 (on
the Home Page the messages “EXT” and “OFF” appear alter-
nately at bottom right).
For the connection of the inputs see par. 6.2.1

Table 6: Factory settings
Page 8.0 If a twin system is used (see Par. 6.3) on page 8.0 you can set
one of the 3 possible twin operation modes:
Alternate every 24h: The 2 circulators alternate in reg-
ulation every 24 operating hours. If one of the 2 mal-
functions, 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
ow 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
automatically gure as Single, working completely independent
of each other.
