Lochinvar Lectrus electric boiler (KEB) BACnet points list
Updated 4 November 2026
The Lectrus electric boiler uses the same Lochinvar Modbus/BACnet communication board and object scheme as the SMART TOUCH gas units, with its own names in an 'Electric Object Name' column. Binary values take the boiler and DHW enable commands, binary inputs give flow, pressure, LWCO and limit status plus relay and pump states, analog inputs give setpoints, temperatures, modulation and status codes, and analog values take the BAS configuration bits, rate command and remote temperatures.
This page lists 39 BACnet objects for the Lochinvar Lectrus electric boiler (KEB) — 10 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Lochinvar’s own free documentation, linked below.

BMS integration notes: Lochinvar Lectrus electric boiler (KEB)
At the control (installer code 5309, Control Modes) set BMS / ModBus-BACnet to Active, then write AV 0 Configuration so the boiler knows which values the BAS will supply. The BAS then sends the enable (BV 0, or the packed AV 1), a rate command (AV 2), or both, and keeps rewriting them. Status, temperatures and codes can be read without taking control.
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.
| Object | Name | Why | Access |
|---|---|---|---|
| AV 0 | Configuration | Bitmask of BAS-supplied inputs; resend before commands | Write |
| BV 0 | Boiler Enable | Enable / call for heat from the BAS | Write |
| AV 2 | 0-10V BMS Input | Rate command: modulation % or setpoint, per BMS Type | Write |
| AI 13 | Boiler Status Code | What the boiler is doing | Read |
| AI 8 | Outlet Temperature | Boiler outlet water temperature, °C | Read |
| AI 11 | Modulation Rate | Heating modulation rate, % | Read |
| AI 15 | Boiler Lockout Code | Active lockout code | Read |
Enable & remote start
Control Mode 1: local setpoints plus BAS enable (AV 0 = 0x0001, AV 1 = 0x0001). Control Mode 2: enable plus AV 2 rate command; BMS Type sets whether AV 2 is modulation % (POWER) or a temperature setpoint (SETPOINT, default). Set BMS to ACTIVE in Control Modes for rate control.
Heartbeat & communication loss
The Modbus T/O timer (installer code 5309, Control Modes, Modbus T/O; 5-120 s, default 10 s) is reset by every write with new temperatures or commands; if it runs out the boiler reverts to its own controls. Commands without temperatures must still be refreshed at least every 4 minutes. Lochinvar recommends the shortest timer setting.
Sensors & values from the BMS
Set the AV 0 bits for the values the BAS will supply, then write AV 3 tank setpoint, AV 4 tank temperature, AV 5 outdoor temperature, AV 6 system supply temperature or AV 7 DHW recirculation temperature, and keep refreshing them.
Network setup
- MAC address from dip switches 1-8 (master, so 0-127); baud from switches 9-10: 9600, 19200, 38400 or 76800.
- Device instance = base 600000 + MAC address; the base can be changed (0-4194048) and reset by powering up with dip switches 1-8 on.
- Default device name is "MTR-01 BACnet".
Watch out for
- The manual says to resend the AV 0 configuration bits before each command.
- In a cascade only the leader needs the board for control; it then reports cascade totals only.
- Without BMS mode active the board is monitor-only.
- The memory map is shared with gas models; ignore gas-only names when reading the PDF.

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 Lectrus electric boiler (KEB) and exports what it actually has to Excel — free. New to BACnet?

Questions about the Lochinvar Lectrus electric boiler (KEB)
How many BACnet points does the Lochinvar Lectrus electric boiler (KEB) have?
This list has 39 BACnet objects: 15 analog inputs, 8 analog values, 14 binary inputs, 2 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Lochinvar Lectrus electric boiler (KEB) BACnet points are writable?
10 of the 39 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 Lochinvar Lectrus electric boiler (KEB) BACnet documentation?
The source is Modbus and BACnet Communication Instructions - Models KEB 0015-0150 (100389961_2000844370), revision Rev A, published free by Lochinvar at https://assets.lochinvar.com/damroot/Original/10017/MODB-I-O-KEB_100389961_2000844370_Rev_A_(63600).pdf.
What are the minimum BACnet points to integrate the Lochinvar Lectrus electric boiler (KEB)?
Start with AV 0 Configuration (Bitmask of BAS-supplied inputs; resend before commands); BV 0 Boiler Enable (Enable / call for heat from the BAS); AV 2 0-10V BMS Input (Rate command: modulation % or setpoint, per BMS Type); AI 13 Boiler Status Code (What the boiler is doing); AI 8 Outlet Temperature (Boiler outlet water temperature, °C); AI 11 Modulation Rate (Heating modulation rate, %); AI 15 Boiler Lockout Code (Active lockout code).
How do I enable BMS control of the Lochinvar Lectrus electric boiler (KEB)?
Control Mode 1: local setpoints plus BAS enable (AV 0 = 0x0001, AV 1 = 0x0001). Control Mode 2: enable plus AV 2 rate command; BMS Type sets whether AV 2 is modulation % (POWER) or a temperature setpoint (SETPOINT, default). Set BMS to ACTIVE in Control Modes for rate control.
Does the Lochinvar Lectrus electric boiler (KEB) need a BACnet heartbeat or have a communication timeout?
The Modbus T/O timer (installer code 5309, Control Modes, Modbus T/O; 5-120 s, default 10 s) is reset by every write with new temperatures or commands; if it runs out the boiler reverts to its own controls. Commands without temperatures must still be refreshed at least every 4 minutes. Lochinvar recommends the shortest timer setting.
Can the BMS supply sensor values to the Lochinvar Lectrus electric boiler (KEB)?
Set the AV 0 bits for the values the BAS will supply, then write AV 3 tank setpoint, AV 4 tank temperature, AV 5 outdoor temperature, AV 6 system supply temperature or AV 7 DHW recirculation temperature, and keep refreshing them.
How do I check these points on the real Lectrus electric boiler (KEB)?
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.
