Power Supply: 1 x 115V ±10%, 50/60Hz and
1 x 208-230V ±10%, 50/60Hz
The NEC and local codes must be followed at all times.
The branch circuit supplying power to the pump must be
tted with a suitably sized circuit breaker. If a ground
fault CB is used, ensure that the CB is suitable for use
with inverter driven appliances.
2.1 Power supply connection
1. Open the terminal box cover removing the screws, g. 4.
2. Tighten the ½” NPT electrical tting into the conduit
connection of the pump.
3. Route power wiring through conduit to the terminal
block.
4. Connect the electrical conduit to the ½” NPT tting.
a. Connect the ground (earth) wire; be sure that
the ground (earth) wire is sized at least as large as
the phase wires.
b. Connect the phase wires.
5. Close the terminal box cover.
CAUTION:
If stranded wire is used to connect power to the
pump make sure that all individual strands enter the
terminal block as the wire is inserted. Peeled back
strands can cause a short circuit hazard at the pump
terminal block connections.
2.2 I/O connection
1. Open the terminal block removing the screws.
2. Connect the control wiring according to the terminal
block diagram. See Figure 6 in the appendix and
the requirements of sec. 2.3 and 2.4.

2.5 I/O description
2.5.1 External start/stop [(11) (12)]
The circulator can be started or stopped via an
external potential-free contact or a relay connected to
terminals (11) and (12). If no external start/stop switch
is connected, the terminals (11) and (12) should stay
jumpered, per factory default.
NOTES:
• The drive provides 5VDC through these terminals: no
external voltage must be provided to these terminals!
•The number of ON/OFF power cycles for the pump
must be less than 3 times per hour and less than
20/24 hours. If more frequent start/stop cycles are
required, the use of a dedicated start/stop input is
recommended. See External start/stop above.
2. Electrical Installation
(Do not run high volt wiring
for fault signal relay through
these glands)

2.5.4 External analog input 4-20mA [(9) (10)]
The circulator can be equipped with a 4-20mA external
differential pressure sensor, connected to terminals (9)
and (10), with the purpose of increasing the precision in
operating modes involved with pressure regulation.
For setting the correct pressure sensor model in the
drive, see sec. 4.3.5.3.
2.5.5 External temperature sensor [(13) (14)]
The circulator can be equipped with an external KTY83
temperature probe (1KΩ at 25°C), connected to ter-
minals (13) and (14), with the purpose of measuring an
absolute or a differential water temperature, in tempera-
ture dependent / inuenced operating modes.
2.5.6 Communication bus (standard)
[(15) (16) (17)]
The circulator can communicate remotely through a
built-in RS485 port, whose characteristics are:
Interface RS485 (TIA/EIA) optically isolated
Baud rate 4800 / 9600 (factory setting) / 14400 /
19200 / 138400 / 56000 / 57600 baud
Data format 8 data bits, no parity, 1 stop bit
Protocol Modbus RTU (factory setting)
BACnet MSTP
1-247 Modbus RTU
Address 0-127 Bacnet MSTP
ID #1 factory setting
For setting the correct communication parameters in the
drive, see sec. 4.3.5.2.
NOTE:
This communication bus, implemented on terminals
(15), (16) and (17), is the only one which can be used
for connecting 2 pumps in dual pump operations (see
sec. 4.3.5.1).
2.5.7 Communication bus (optional)
[(18) (19) (20)]
The circulator can communicate remotely through the

2.5.8 Optional wireless and RS485 module
[(21)]
The drive can be equipped with
• an optional Wireless module or
• an optional RS485 module
Both modules can be plugged inside the drive (see
Figure 8 in the appendix) by the provided clips and with
the cable connected to the connector (21).
2.6 Settings priority
All the I/O signals, described in 2.5, can interact to-
gether changing the behavior of the circulators they are
connected to. If two or more signals are enabled and
active at the same time, the circulator will operate
according to the setting with the highest priority.
Refer to the table below for the settings priority:

7 Stop
Example 1
In case the external start/stop switch is open or
unconnected (External Start/Stop = Stop), the drive will
not accept any speed regulation.
Example 2
The circulator can be operated through the User
Interface only if no external signals are applied (to the
provided terminals) and no communication bus is con-
nected.
3. Initial Start-up
Before operating the circulator, verify that wires are
correctly and rmly terminated into the terminal blocks.
1. Switch on the power supply to the pump
The drive lights on all the LEDs of the User Interface,
to allow a quick detection of any display malfunction.
2. After few seconds, the drive will display the message
“SING”.
While this message (“SING”) is displayed, the drive
allows the possibility to set the dual pump operations’
parameters: if the user does not change this setting,
the device will default to the factory setting (single-
head pump) and proceed to the next step.
For setting up the correct dual pump operations’
parameters in the drive, see sec. 4.3.5.1.
3. After a few seconds, the drive will display the
message “COMM”.
While this message (“COMM”) is displayed, the drive
allows the possibility to set the communication
parameters: if the user does not change this
setting, the device will default to the factory settings
(9600baud, address = 1, no optional module, Modbus
RTU protocol) and proceed to the next step.
For setting up the correct communication parameters
in the drive, see sec. 4.3.5.2.
4. If a pressure sensor is connected to terminals P+ and
P-, the drive will display the message “PRES”.*
While this message (“PRES”) is displayed, the drive
allows the possibility to set the optional external
differential pressure sensor’s parameter. If the user
does not change this setting, the device will default
to the factory setting (differential pressure sensor 15
PSID (1.0bar) and proceed to the next step.
For setting the correct differential pressure sensor’s
parameter in the drive, see sec. 4.3.5.3.
5. After a few seconds, the drive will display the
message “4DEG”.
While this message (
“4DEG” ) is displayed, the drive
is performing the rst (out of 4) cycles of the Air Purge
procedure: if the user does not stop this procedure,
the device will complete the 4 cycles (decrementing
in each sub-phase the countdown “4DEG”- “3DEG”-
“2DEG”-“1DEG”) and then proceed to the next step.
To stop or start the Air Purge procedure, see
sec. 4.3.4.2.
6. At the end of the Air Purge procedure, the pump
starts pumping in Constant Pressure control mode
(factory default)
For more information about Control Modes and
relative default value, see sec. 4.3.3
NOTE:
All 5 steps (1-5) stated under “Initial Start-up” will repeat
in the same manner for any subsequent start-up.
In step 6, the start-up control mode will always be the
last control mode used before the previous power off.
* Only if an external differential pressure sensor is connected to the provided
terminals (see 2.5.4)

When the Power (green) LED is lit, the circulator is
supplied with power and the electronic devices are
operative.
4.1.2 Status indicator [(8)]
• If the “Status” LED is not lit, then the pump is
stopped or disabled and the pump motor is not
running.
• If the Status (orange) LED is lit, then the pump is
stopped and the pump motor is not operating due to a
non-blocking alarm
• If the Status (red) LED is lit, then the pump is stopped
or disabled and the pump motor is not running due to a
blocking error
• If the Status (green) LED is lit, then the pump is
operating
4.1.3 Remote control indicator [(9)]
The way the Remote LED is lit (permanently) or blinks,
depends on various settings and conditions as below
4.1.3.1 Condition 1
If no optional wireless or RS485 module is used
(referring to sec. 4.3.5.2, parameter “Module” is set to
value “None”) and the protocol for the communication
bus is Modbus RTU (parameter “Protocol” is set to
value “Modbus”)
• If the Remote LED is not lit, then the drive does not
detect any valid Modbus message on the terminals
provided for the communication bus
• If the Remote (green) LED is permanently lit, then the
drive both:
• detected a communication bus on the provided
terminals
• acknowledged the correct addressing
4. Control Panel
• If the Remote (green) LED is blinking with 50% duty
cycle, then the drive:
• detected a communication bus on the provided
terminals but has not been correctly addressed
Reasons for this condition are the following:
• If the Remote (green) LED switches from being
permanently lit to being not lit, then the drive did not
detect any valid Modbus RTU message (at least) for
the last 5 seconds
• If the Remote (green) LED switches from being
permanently lit to blinking with 50% duty cycle, then
the drive has not been correctly addressed (at least)
for the last 5 seconds
4.1.3.2 Condition 2
If no optional wireless / RS485 module is used (refer-
ring to sec. 4.3.5.2, parameter “Module” is set to value
“None”) and the protocol for the communication bus is
BACnet MSTP (parameter “Protocol” is set to value
“BACnet”)
• If the Remote LED is not lit, then the drive did not
receive any valid request, coming from any BACnet
MSTP device, (at least) for the last 5 seconds
• If the Remote (green) LED is permanently lit, then the
drive is exchanging information with BACnet MSTP
device
4.1.3.3 Condition 3
If the optional wireless module is used (referring to sec.
4.3.5.2, parameter “Module” is set to value “Wireless”)
• If the Remote LED is not lit, then the connection with
the wireless module is damaged or absent.
• If the Remote (green) LED is blinking with 10% duty
cycle, then the drive is exchanging information with the
wireless module.
4.1.3.4 Condition 4
If the optional RS485 module is used (referring to sec.
4.3.5.2, parameter “Module” is set to value “RS485”)
• If the Remote LED is not lit, then either
• the connection with the RS485 module is damaged
or absent
• the drive didn’t receive any valid request, coming
from any other external device, (at least) for the
last 5 seconds
• If the Remote (green) LED is blinking with 90% duty
cycle, then both:
• the RS485 module is correctly connected
• the drive is exchanging information with an
external device

4.3.3 Control modes
Referring to Figure 7 in the appendix, short press the
Control mode button (1) to select the desired control
mode, following this logical ow:
NOTE:
All control modes can be combined with the Night Mode
function (see sec. 4.3.4.1)
4.3.3.1 Constant Pressure (Head)
The circulator maintains a constant differential pressure
at any ow demand;
for setting up the desired head of the pump (Hset), see
sec. 4.3.1.
When Constant Pressure (which is the factory setting)
is the selected control mode, the indicator is
permanently lit.
If the hydraulic working point allows the circulator to
be operated by regulating the head within the electric
power limits, then the target head will coincide with the
desired (set) head.
If the hydraulic working point requires the circulator to
be operated at a working point that exceeds the electric
power limits, then the target head will be de-rated to
remain within the maximum power limitation curve.
4.3.3.2 Proportional pressure (head)
The circulator pressure is continuously increased/
decreased depending on the increased/decreased ow
demand;
for setting up the desired maximum head of the pump
(Hset), see sec. 4.3.1.
When Proportional Pressure is the selected control
mode, the indicator is permanently lit.
If the hydraulic working point allows the circulator to
be operated by regulating the head within the electric
power limits, then the target head will coincide with the
desired (set) head.
If the hydraulic working point requires the circulator to
be operated at a working point that exceeds the electric
power limits, then the target head will be de-rated to
remain within the maximum power limitation curve.
4.3.3.3 Fixed speed
The circulator maintains a xed speed at any ow
demand;
for setting up the desired speed of the pump, see
sec. 4.3.1.
When Fixed Speed is the selected control mode, the
indicator is permanently lit
If the hydraulic working point allows the circulator to
be operated by regulating the speed within the electric
power limits, then the target speed will coincide with the
desired (set) speed.
If the hydraulic working point requires the circulator to
be operated at a working point that exceeds the
electric power limits, then the target speed will be
de-rated to remain within the maximum power limitation
curve.

4.3.4 Special functions
4.3.4.1 Night mode
The Night Mode function cannot be used in cooling
systems.
Prerequisites:
• The circulator is installed in the supply line
• The “night condition” can be detected with good con-
dence if a higher-level control system is set to change
the supply temperature
When Night Mode is activated, by short pressing the
Control mode button (1) as described in sec. 4.3.3,
the indicator is permanently lit.
The Night Mode can be active in combination with each
one of the Control Modes described in sec. 4.3.3.
This function reduces the power consumption of the
circulator to the minimum when the heating system is
not running; an algorithm detects the proper working
conditions and automatically adjusts the speed of the
pump.
The pump returns to the original set point as soon as
the heating system restarts.
4.3.4.2 Air purge (Degassing)
At each power-on, the drive performs (factory default)
an automatic Air Purge procedure, with the aim of
ushing out air pockets from the circulator housing.
The Air Purge cycle will run the pump at a xed speed
for a predetermined length of time, followed by a shorter
period of minimum speed; this cycle will be repeated 4
times (in total approximately 60 seconds), with the mes-
sage 4DEG reporting the corresponding decrementing
counter (as described in sec. 3).
Referring to Figure 7, in the appendix:
• the Air Purge can be skipped or started up (at any
time) by short pressing (for about 2 seconds) both the
Setting buttons (5) (Up and Down arrow) together
• the Air Purge can be permanently enabled or disabled
(at any time) by long pressing (for at least 10seconds)
both the Setting buttons (5) (Up and Down arrow)
together: by this operation, in case of Air Purge initially
enabled (factory default), after 10 seconds the drive
will display the message dGOF. On the other hand, if
the Air Purge is initially disabled, then keeping the
button pressed for 10 seconds, will enable the Air
Purge and the drive will display the message dGOn.

4.3.5.1 Dual pump operations settings
Each electronic drive can be congured to couple with
another drive, so that they start working in concert in
dual pump operation.
Prerequisites:
• Dual pump operation is available only when identical
pumps are used.
• Wire both pumps to terminals (15), (16) and (17) as
described in sec. 2.4 and sec. 2.5.6, connecting the
2x single-head pumps.
For a correct automatic conguration, follow the
subsequent procedure, by rst setting the pump
selected to be the master of the couple
1. Switch on the power supply to both the pumps
2. After few seconds, the drive will display the message
SING.
3. While this message (“SING”) is displayed, press
shortly one of the Setting buttons (5), in order to
congure the circulator as:
• Single Head Pump (factory default): the message

bCUP is ashing onto the Numeric Display (6).
In this conguration, only the master pump runs, while
the second pump starts in case of failure of the master
pump.
• Alternate operation: the message ALTE is ashing
onto the Numeric Display (6).
In this conguration, only one pump runs at a time.
The working time is switched every 24 hours so that
workload is balanced between both pumps. The
second pump starts immediately in case of failure of
the running pump. The 24 hour alternating time is
non-adjustable.
• Parallel operation: the message PArA is ashing onto
the Numeric Display (6).
In this conguration, both pumps run simultaneously
with the same set point. The master pump determines
the behavior of the full system and is able to optimize
the performance. To satisfy the required performance,
the master pump starts or stop the second pump
depending on the required head and ow.
• Forced parallel operation: the message FOrC is
ashing onto the Numeric Display (6).
In this conguration, both pumps always run
simultaneously at the same set point.
7. Press shortly the Parameter button (3) to conrm the
value selected.
The Numeric Display (6) stops ashing: the congura-
tion is nalized and the drive will proceed to the next

Once the master pump is congured, the second pump
(slave) is then automatically congured by the master
pump. To verify this, the Remote (green) LED is
permanently lit.
In case the automatic conguration of the second pump
(slave) did not take effect (Remote LED not lit), repeat
the above procedure, from step 1 to step 4, conguring
the second pump to be a Dual Slave Pump.
