Backup Operation: the message
bUp
(
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.
3, step 2.
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.
NOTICE
Whenever a couple of pumps, connected in Dual
Pump Operations, are required to communicate
remotely with a BMS or a generic external device, then
the Optional Communication Bus, described in par.
2.5.7, shall be activated through the installation of an
optional module (see par. 2.5.8) exclusively into the
Master pump of the couple
4.3.5.2
Communication settings
Each electronic drive (model ecocirc XLplus only) can
communicate remotely through a built-in RS485 port,
as briefly described in par. 2.5.6.
Referring to
models) and to
connected models), the communications settings are
accessible following the subsequent procedure.
1. Switch on the power supply to the pump
2. After few seconds, the drive will display the
message

(
10
) or
CONN
(
11
).
3. While this message (
“COM” or “COMM”) is
displayed, press shortly the Parameter button
in order to configure the subsequent
parameters:
Baud Rate: the message
bdr
(
10
) or
bAUd
(
11
) is displayed onto the Numeric
Display
:
by
mean
of
it,
the
communication port baud rate is set to a
specific value.
Available values for this parameter are:
- 4.8 kbps
- 9.6 kbps (factory default)
- 14.4 kbps
- 19.2 kbps
- 38.4 kbps
- 56.0 kbps
- 57.6 kbps.
Protocol
12
: the message
prOt
is
displayed onto the Numeric Display
: by
mean of it, the user can select a specific
protocol on the communication port.
Available values for this parameter are:
- Modbus

(factory default)
- Bacnet
bAC
.
Address: the message
Add
(
10
) or
Addr
(
11
) is displayed onto the Numeric
Display
: by mean of it, the circulator
address is set to a specific value (1 is the
factory default).
Available values for this parameter are:
- [1
247] (in case of Modbus
protocol)
- [0
127]
(in
case
of
Bacnet
protocol)
Module: the message
NdL
(
10
) or
NOdU
(
11
) is displayed onto the Numeric
Display
: by mean of it, the user
specifies the possible presence, into the
drive, of one optional module.
Available values for this parameter are:
- None
