Xylem Lowara Smart Pump e-LNEE / e-LNES / e-LNTE / e-LNTS (in-line) BACnet points list
Updated 4 November 2026
The Lowara Smart Pump in-line pumps have BACnet MS/TP built into the drive. Analog Values carry start/stop, control mode, speed and pressure setpoints and drive settings; Analog Inputs give speed, pressure, current, power, temperatures, error and alarm codes, an error log and, on twin sets, the follower pump's readings.
This page lists 64 BACnet objects for the Xylem Lowara Smart Pump e-LNEE / e-LNES / e-LNTE / e-LNTS (in-line) — 21 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Xylem’s own free documentation, linked below.

BMS integration notes: Xylem Lowara Smart Pump e-LNEE / e-LNES / e-LNTE / e-LNTS (in-line)
Wire RS-485 to the drive (the twin master needs the RS485 module), set P51 MAC address and P53 device ID offset, and pick a baud rate (38400 suggested). Write AV 1 for the control mode and the matching setpoint (AV 2 speed, AV 4 constant pressure or AV 19 proportional pressure), then AV 0 = 0 to start.
Minimum points to map
The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Enable & remote start
AV 0 STOP START starts (0) or stops (1) the pump; AV 1 picks the control mode whose setpoint applies.
Network setup
- MS/TP master; baud 4800-57600, 38400 suggested (4800 gives frequent timeouts).
- MAC address is parameter P51 Address, factory 1.
- Device instance factory 84002; set with P53 BACnet device ID offset.
- RS-485 on terminals 15 (B1), 16 (A1), 17 (GND) on single-phase drives or 7 (B1), 6 (A1), 5 (GND) on three-phase drives.
Watch out for
- While BACnet communication is active most parameters are locked at the drive keypad.
- Set P69 Avoid frequent parameters saving = yes (AV 13) if the BMS writes setpoints often, to spare the EEPROM.
- AV 9 RESET DEFAULT restores factory values; do not write it routinely.
- On twin sets set P51 and P53 on the master pump only.

Integration notes
- The device instance is 84002 from the factory; change it with parameter P53 (BACnet device ID offset) or by writing the Device object's Object_Identifier.
- AV 0 uses inverted logic: 0 = start, 1 = stop.
- Setpoint limits and defaults depend on the pump model; speed limits come from P26/P27.
- Bit-field AIs (10, 11, 13, 14 and the log/follower fields) must be split into bits; the manual lists each bit.
- AI 17-32 show one row of the 8-row error log, chosen with AV 8.
- Objects the manual marks "N. A." (not used) or "RESERVED" are left out.
- Twin (dual pump) sets: only the master is wired to the BMS (it needs the RS485 Module Smart Pump); follower data appears on AI 38-49.
Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the Lowara Smart Pump e-LNEE / e-LNES / e-LNTE / e-LNTS (in-line) and exports what it actually has to Excel — free.

Questions about the Xylem Lowara Smart Pump e-LNEE / e-LNES / e-LNTE / e-LNTS (in-line)
How many BACnet points does the Xylem Lowara Smart Pump e-LNEE / e-LNES / e-LNTE / e-LNTS (in-line) have?
This list has 64 BACnet objects: 43 analog inputs, 21 analog values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Xylem Lowara Smart Pump e-LNEE / e-LNES / e-LNTE / e-LNTS (in-line) BACnet points are writable?
21 of the 64 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done.
Where is the official Xylem Lowara Smart Pump e-LNEE / e-LNES / e-LNTE / e-LNTS (in-line) BACnet documentation?
The source is Smart Pump Range BACnet Protocol Parameter List (001086068 EN rev. C), revision 04/2021, published free by Xylem at https://www.xylem.com/siteassets/brand/lowara/resources/manual/001086068en_c_04_2021_bacnet.pdf.
What are the minimum BACnet points to integrate the Xylem Lowara Smart Pump e-LNEE / e-LNES / e-LNTE / e-LNTS (in-line)?
Start with AV 0 STOP START (Start/stop (0 = start, 1 = stop)); AV 1 CONTROL MODES (Control mode: 0 ACT, 1 CPP, 2 PPP/MSE, 3 MSY); AV 2 RPM SETPOINT (Speed setpoint in ACT mode, rpm); AV 4 CONST HEAD S.P (Constant pressure setpoint (CPP)); AV 19 PROP HEAD S.P. (Proportional pressure setpoint); AI 0 MEASURED RPM (Motor speed, rpm); AI 1 MEASURED HEAD (Measured pressure, bar/psi per AV 3); AI 4 INPUT POWER (Input power, W); AI 12 ALARM CODE (Current alarm code); AI 9 ERROR CODE (Current error code).
How do I enable BMS control of the Xylem Lowara Smart Pump e-LNEE / e-LNES / e-LNTE / e-LNTS (in-line)?
AV 0 STOP START starts (0) or stops (1) the pump; AV 1 picks the control mode whose setpoint applies.
How do I check these points on the real Lowara Smart Pump e-LNEE / e-LNES / e-LNTE / e-LNTS (in-line)?
Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
