3 First Start-up
Before operate the circulator, verify the correct
connection of the wirings.
1. Switch on the power supply to the pump
The drive light all the LEDs of the User Interface,
to allow a quick detection of any display
malfunction
2. (6) After few seconds, the drive will display the
message SIN (7) or SING (8)
While this message (“SIN” or “SING”) is displayed,
the drive gives 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, in the drive, the correct dual pump
operations’ parameters see par. 4.3.5.1.
3. (6) After few seconds, the drive will display the
message CON (7) or CONN (8)
While this message (“COM” or “COMM”) is
displayed, the drive gives 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, in the drive, the correct communication
parameters see par. 4.3.5.2.
4. (9) After few seconds, the drive will display the
message PrE (7) or PrES (8)
While this message (“PRE” or “PRES”) is
displayed, the drive gives the possibility to set the
differential pressure sensor’s parameter: if the user
does not change this setting, the device will default
to the factory setting (differential pressure sensor
1.0bar) and proceed to the next step.
For setting, in the drive, the correct differential
pressure sensor’s parameter, see par. 4.3.5.3.
5. After few seconds, the drive will display the
message 4dG (7) or 4DEG (8)
While this message (“4DG” or “4DEG”) is
displayed, the drive is performing the first (out of 4)
cycle of the Air Purge procedure: if the user does
not stop this procedure, the device will finalize the
4 cycles (decrementing in each sub-phase the
countdown “4DG”-“3DG”-“2DG”-“1DG” or “4DEG”“3DEG”-“2DEG”-“1DEG”) and then proceed to the
next step.
To stop or start the Air Purge procedure, see
par.4.3.4.2
6. At the end of the Air Purge procedure, the pump
starts pumping in Constant Head control mode
(factory default)
For more information about Control Modes and
relative default value, see par. 4.3.3
NOTICE
All the steps from 1 to 5 are always the same at every

4.1 LEDs description
4.1.1 Power indicator []
When the Power (green) LED is lit, the circulator is
supplied with power and the electronic devices are
operative
4.1.2 Status indicator []
If the 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
still enabled and the pump motor is running,
because in presence of 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
running
4.1.3 Remote control indicator []
This indicator is used only on ecocirc XLplus
circulators, because it is related to the presence of any
kind of communication.
The way the Remote LED is lit (permanently) or blinks,
depends on several settings and conditions as below

If no optional wireless / RS485 module is used
(referring to par. 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 LED is not lit, then the drive cannot
detect any valid Modbus message on the terminals
provided for the communication bus
4.1.3.2 Condition 2
If no optional wireless / RS485 module is used
(referring to par. 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 LED is not lit, then the drive didn’t
receive any valid request, coming from any other
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 any other
Bacnet MSTP device
4.1.3.3 Condition 3
If the optional wireless module is used (referring to par.
4.3.5.2, parameter “Module” is set to value “Wireless”)
If the 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 every second, then the drive is exchanging

2. Change the value with the Setting buttons
A short button pressure will vary the set point by
one single step, but if a button is kept pressed, the
variation will progress automatically in the selected
direction, with an acceleration factor proportional
to the pressure time
3. Wait 4 seconds to store and activate the new
set point
When the change is confirmed, the Numeric
display stops blinking and gets back to the
measurement visualization active before entering
the edit operation
NOTICE
During the Set points editing (while the Numeric
display is blinking), any pressure of the Parameter
button is inhibited, therefore changing the
measurement selected is impossible. To do that, wait
till the end of the edit operation
4.3.2 Operating Modes
Referring to Figure 10 (in case of plug-connected

The Night Mode function cannot be used in cooling
systems.
Prerequisites:
The circulator is installed in the supply line
10
11
The “night condition” can be detected with
good confidence if a higher-level control
system is set to change the supply
temperature
When Night Mode is active, by short pressing the
Control mode button as described in par. 4.3.3, the
Once the lock is active, by pressing any button the
drive displays the symbol (10) or (11);
unlocking the Control Panel, the drive will display the
symbol (10) or (11).
indicator is permanently lit
The Night Mode can be active in combination with
each one of the Control Modes described in par. 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
At each power-on, the drive performs (factory default)
an automatic Air Purge procedure, with the aim of
flushing air pockets from the circulator housing.
The Air Purge cycle will run the pump at fixed speed
for a predetermined length of time, followed by a
shorter period of minimum speed; this cycle will be
repeated 4 times (in total around 60sec), with the
message 4dG (10) or 4DEG (11) reporting the
corresponding decrementing counter (as described in
par. 3).
Referring to Figure 10 (in case of plug-connected
models) and to Figure 11 (in case of terminalconnected models),
the Air Purge can be skipped or started up (at
any time) by short pressing (for around 2 sec)
both the Setting buttons (Up and Down
arrow) together
the Air Purge can be permanently enabled or
disabled (at any time) by long pressing (for at
least 10sec) both the Setting buttons (Up
and Down arrow) together: by this operation, in
case of Air Purge initially enabled (factory
default), after 10sec the drive will display the
message DGOf (11). On the contrary, in
case of Air Purge initially disabled, after 10sec
the drive will display the message DGOn
(11).
4.3.4.3 Keypad Lock
Keypad Lock is a function with which the drive disables
all the buttons of the Control Panel, but maintains
running all the indicators and the numeric display.
The Control Panel can be locked/unlocked by pressing
simultaneously, and for two seconds, the Parameter
button and the Up arrow button .
In any case, the drive will automatically lock the user
interface after 10 minutes from the last button
pressure.

4.3.5 Sub-Menus (Parameters)
4.3.5.1 Dual Pump Operations settings
Each electronic drive (model ecocirc XLplus only) can
be configured for being coupled with another one, so
that they start working in concert in dual pump
operations.
The dual pump operation is factory configured in case
of a twin-head pump, but can be set up even in case of
a spare part drive or if it’s necessary to have 2x singlehead pumps working in concert.
Prerequisites:
2x single-head pumps available with same part
number
3-wire bus cable, wired through the terminals
, and as described in par. 2.4 and par.
2.5.6, connecting the 2x single-head pumps
For a correct automatic configuration, follow the
subsequent procedure, setting first the pump selected

(10) or bCUP (11) is flashing onto the
Numeric Display .
In this configuration, only the master pump
runs, while the second pump starts in case
of failure of the master pump.
Alternate Operation (factory default): the
message ALt (10) or ALtE (11) is
flashing onto the Numeric Display .
In this configuration, only one pump runs
at the 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.
Parallel Operation: the message PAr
(10) or PArA (11) is flashing onto the
Numeric Display .
In this configuration, 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 guarantee the
required performance minimizing at the
same time the power consumption, the
master pump starts or stops the second
pump depending on the required head and
flow.
Forced Parallel Operation: the message
FOr (
10
) or FOrC (11) is flashing onto
the Numeric Display .
In this configuration, both pumps always
run simultaneously with the same set
point.
7. Press shortly the Parameter button to
confirm the value selected
The Numeric Display stops flashing: the
configuration is finalized and the drive will
proceed to the next step as described in par.

Once the master pump is configured, the second pump
(slave) is then automatically configured by the master
pump, to testify it, the Remote (green) LED is
permanently lit.
In case the automatic configuration of the second
pump (slave) did not take effect ( LED not lit),
repeat the above procedure, from step 1 to step 4,
configuring the second pump to be a Twin (Dual)
Slave Pump.

6 Accessories
6.1 External Temperature Sensor
As briefly described in par. 2.5.5, the circulator can be
equipped with an external KTY83 temperature probe
(1KΩ at 25C), with the purpose of measuring an
absolute or a differential water temperature, in
temperature dependent / influenced control modes.
6.1.1 Water Temperature dependent
Control Modes – Setting parameters
The subset of parameters collected in Parameters
Table 2 (described in par. 8.2.1.2) is devoted to set the
Water Temperature dependent Control Modes; in
particular:
0x0030 - Temperature Control Mode
Defines if there’s a dependency of the control
modes on the temperature, and which kind of
dependency
o [= 0] None of the standard control mode
(described in par. 4.3.3) is affected or
influenced by the water temperature
o [= 1] The control modes usually
managing the differential pressure control,
Constant Pressure [ConstP] (see par.
4.3.3.1) and Proportional Pressure
[PropP] (see par. 4.3.3.2), are influenced
by water temperature ([ConstP]/T and
[PropP]/T)
o [= 2] The active control mode is

o [= 0] The control mode uses the internal
temperature probe’s input signal
o [= 1] The control mode uses the
auxiliary (external) temperature sensor’s
input signal (the external temperature
sensor must be connected)
o [= 2] The control mode calculates the
differential temperature between the
internal and the external sensor, and uses
the differential temperature as input signal
(the external temperature sensor must be
connected)
0x0034 – Temperature Slope
Defines how the Head set-point (when
ConstantΔP/T or PropΔP/T control modes are
active) reacts to the water temperature’s
increase/decrease

Is the proportional constant used in the PIregulator which leads the temperature control
0x0036 – Ki for Temperature Control
Is the integral constant used in the PI-regulator
which leads the temperature control
0x0037 – Temperature Control sampling time
Sampling time used in the temperature control
6.1.2 Water Temperature dependent
Control Modes
Using the setting parameters described in par. 6.1.1,
the Water Temperature dependent Control Modes are
then the following:
6.1.2.1 Constant Absolute Temperature [ConstT]
This control mode ensures a constant water
temperature. Constant temperature is a comfort control
mode that can be used in domestic hot-water systems
to control the flow to maintain a fixed temperature in
the system
In this control mode, the basic assumption is that the
circulator regulates (following the feedback of the
internal or external temperature sensor) the water
temperature in a point, on the return pipe of the
system, as close as possible to the consumer
(radiator, heat exchanger, …).
It is then clear that the ConstT control mode can be
deployed in the subsequent possible application
o ConstT for heating applications, using internal
temp. sensor
In this application the pump is installed in the
return pipe, and utilizes the internal temp. sensor
According to what described in par. 6.1.1, the
necessary correspondent settings are:
- 0x0030 - Temperature Control Mode = 2
- 0x0031 – Absolute Temperature Setpoint =
desired value in the range [20°C ÷ 110°C]
- 0x0033 – Temperature Probe = 0
- 0x0034 – Temperature Slope = 1
o ConstT, for heating applications, using
external temp. sensor
In this application the pump is installed in the flow
pipe, and utilizes the external temp. sensor
According to what described in par. 6.1.1, the
necessary correspondent settings are:
- 0x0030 - Temperature Control Mode = 2
- 0x0031 – Absolute Temperature Setpoint =
desired value in the range [20°C ÷ 110°C]
- 0x0033 – Temperature Probe = 1
- 0x0034 – Temperature Slope = 1
o ConstT, in cooling applications, using internal
temp. sensor
In this application the pump is installed in the
return pipe, and utilizes the internal temp. sensor
According to what described in par. 6.1.1, the
necessary correspondent settings are:
- 0x0030 - Temperature Control Mode = 2
- 0x0031 – Absolute Temperature Setpoint =
desired value in the range [-10°C ÷ 19°C]
- 0x0033 – Temperature Probe = 0
- 0x0034 – Temperature Slope = 0
o ConstT, in cooling applications, using external
temp. sensor
In this application the pump is installed in the flow
pipe, and utilizes the external temp. sensor
According to what described in par. 6.1.1, the
necessary correspondent settings are:
- 0x0030 - Temperature Control Mode = 2
- 0x0031 – Absolute Temperature Setpoint =
desired value in the range [-10°C ÷ 19°C]
- 0x0033 – Temperature Probe = 1
- 0x0034 – Temperature Slope = 0
6.1.2.2 Constant Differential Temperature
[ConstΔT]
This control mode keeps the differential temperature of
the pumped liquid constant, changing the flow rate to
maintain the user-settable set-point
In this case, it’s unnecessary to discriminate between
heating and cooling application, because the
differential temperature is considered as absolute
value.
According to what described in par. 6.1.1, the
necessary correspondent settings are:
- 0x0030 - Temperature Control Mode = 2
- 0x0032 – Differential Temperature Setpoint =
desired value
- 0x0033 – Temperature Probe = 2
6.1.2.3 Constant pressure depending on water
temperature [ConstΔP/T]
In this control mode the drive alters the differential
pressure set-point the pump has to maintain,
depending on the measured fluid temperature, as
depicted in Figure 3
Figure 3
Referring to Figure 3
Tmin = 20C
Tmax = Absolute Temperature Setpoint (par.
0x0031)
Hsmin = 30% of Hsmax
Hsmax = Constant pressure set-point (settable
via User Interface, see par. 4.3.3.1)
The ConstΔP/T control mode can be evidently
deployed in the subsequent possible application
o ConstΔP/T, positive relation P/T, using internal
temp. sensor

desired value
- 0x0033 – Temperature Probe = 1
- 0x0034 – Temperature Slope = 1
- Control Mode = Constant Pressure (settable
via User Interface)
- Constant Pressure Setpoint = desired value
6.1.2.4 Proportional pressure depending on
water temperature [PropΔP/T]
In this control mode the drive alters the proportional
pressure set-point the pump has to maintain,
depending on the measured fluid temperature
Referring to Figure 3
Tmin = 20C
Tmax = Absolute Temperature Setpoint (par.
0x0031)
Hsmin = 30% of Hsmax
Hsmax = Proportional pressure set-point
(settable via User Interface, see par. 4.3.3.2)
According to what already described in par. 6.1.2.3,
even the PropΔP/T control mode can be evidently
deployed in the subsequent possible application
o PropΔP/T, positive relation P/T, using internal
temp. sensor
According to what described in par. 6.1.1, the
necessary correspondent settings are:
- 0x0030 - Temperature Control Mode = 1
