6.5.5 RS485 Interface Parameters
No. Parameter Unit of
measurement Description
P50 Communication protocol [MOD,
BAC]
This parameter selects the specific protocol on the
communication port:

NOD
(MOD): Modbus RTU

BAC
(BAC): BACnet MS/TP.
Default: MOD.
P51 Communication protocol -
Address [1÷247]/[0÷127]
This parameter sets the desired address for the unit,
when connected to an external device, depending on
the protocol selected in P50:

MOD: any value in the 1÷247 range

BAC: any value in the 0÷127 range.
P52 Comm Protocol – BAUDRATE
[4.8, 9.6, 14.4, 19.2, 38.4, 56.0,
57.6 KBPS]
kbps This parameter sets the desired baud rate for the
communication port.
Default: 9.6 kbps.
P53 BACnet Device ID Offset [0÷999] This parameter sets the hundreds, tens and units of
the BACnet Device ID.
Default: 002.
Device ID default: 84002.
P54 Comm Protocol – Configuration
[
8N1
,
8N2
,
8E1
,
8o1
]
This parameter sets the length of the data bits, the
parity and the length of the STOP bits.
Default: 8N1
6.5.6 Test Run Configuration Parameters
Test Run is a function that starts the pump after the last stop, in order to prevent it from blocking.
No. Parameter Unit of
measurement Description
P65 Test Run – Time Start
[0-100]
h This parameter sets the time after which, once the pump has
stopped for the last time, the Test Run will start.
Default: 100 h.
P66 Test Run – Speed
[P27-Max]
rpmx10 This parameter sets the pump rotational speed for the Test
Run.
The Min and Max speeds depend on the pump type.
Default: 200 rpmx10.
P67 Test Run – Time
Duration[0-180]
s This parameter sets the duration of the Test Run.
Default: 10 s.
6.5.7 Special Parameters
No. Parameter Unit of
measurement Description
P68 Default Values Reload
[NO, RES]
If set to RES, after confirmation this parameter performs a
factory reset that reloads the default parameter values.
P69 Avoid Frequent
Parameters Saving [NO,
YES]
This parameter limits the frequency with which the unit stores
the required value P02 in the EEPROM memory, in order to
extend its life.
This could be particularly useful in applications with BMS
control devices that require continuous variation of the value
for fine tuning purposes.
Default: NO.
