Adveco Lincoln L70 BMS Interface (extension board) BACnet MS/TP BACnet points list

Updated 12 November 2026

Short answer

The Lincoln BMS Interface is an extension board that runs central heating (CH) and domestic hot water (DHW) control for a group of Adveco Lincoln L70 air source heat pumps and exposes it on BACnet MS/TP. The BMS can pick the CH and DHW control modes, send demand and flow or tank setpoints, run weather compensation and supplementary heating, and read the board's I/O plus inlet, outlet and ambient temperatures, compressor status, alarms and energy for each of up to 10 Lincolns.

BMS integration notes: Adveco Lincoln L70 BMS Interface (extension board) BACnet MS/TP

Integration in brief

Set ch_mode_select (IV 49) to 4 (BMS Control), then switch heating with ch_bms_demand (BV 36) and set the flow temperature with ch_master_flow_SP (AV 15). For hot water set dhw_mode_select (IV 53) to 3 and use dhw_bms_demand (BV 44) with dhw_flow_SP (AV 18). Read ch_flow_SP and the fault flags.

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
IV 49	ch_mode_select	CH control mode; 4 = BMS Control	Write
BV 36	ch_bms_demand	CH demand from the BMS (1 = active)	Write
IV 53	dhw_mode_select	DHW control mode; 3 = BMS Control	Write
BV 44	dhw_bms_demand	DHW demand from the BMS	Write
AV 15	ch_master_flow_SP	CH flow setpoint in DI/BMS mode, °C	Write
AV 18	dhw_flow_SP	DHW flow setpoint, °C	Write
AI 13	ch_flow_SP	CH flow setpoint in use	Read
BI 37	ch_demand	CH demand active	Read
BI 39	ges_major_fault	Any major fault	Read
BI 40	ges_minor_fault	Any minor fault	Read

Enable & remote start

ch_mode_select (IV 49) = 4 puts central heating under BMS control, switched by ch_bms_demand (BV 36) to the ch_master_flow_SP setpoint; dhw_mode_select (IV 53) = 3 does the same for hot water with dhw_bms_demand (BV 44).

Sensors & values from the BMS

ambient_temp_select (IV 48) picks the ambient temperature for weather compensation and low-ambient logic: the average of all active Lincolns, Lincoln 1 only, or the probe wired to the extension board.

Network setup

BACnet MS/TP on the BMS2 / Fieldbus 2 port; defaults device instance 1, 9600 baud (1200-375000 selectable).
Device instance and baud rate are set with bacnet_device_instance (PIV 118) and bacnet_baudrate (PIV 119); write Reboot_UPC (BV 120) = 1 to apply.

Watch out for

Weather compensation is ignored while CH runs in 4-20 mA or 0-10 V mode.

Integration notes

The guide gives no units; temperatures are in °C going by the prose (for example ch_master_flow_SP default 35 °C).
Per-heat-pump objects (instances 56-117) carry the Lincoln number as the index in the name. Temperatures, compressor status and energy are printed for Lincolns 1 to 10; the minor and major alarm objects are printed for Lincoln 1 only.
Access comes from the guide's Read/Write Mode column: Writeable / Read_Write = W, NoWrite = R.
ch_bms_demand prose says 1 = ON, 2 = OFF in one place and 0 / 1 in another; the BinaryValue object is 0 = inactive, 1 = active.
BACnet type IntegerValue is listed as IV and PositiveIntegerValue as PIV.

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 Lincoln L70 BMS Interface (extension board) BACnet MS/TP and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.

Questions about the Adveco Lincoln L70 BMS Interface (extension board) BACnet MS/TP

How many BACnet points does the Adveco Lincoln L70 BMS Interface (extension board) BACnet MS/TP have?

This list has 120 BACnet objects: 48 analog inputs, 17 analog values, 36 binary inputs, 9 binary values, 8 integer values, 2 positive integer values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Adveco Lincoln L70 BMS Interface (extension board) BACnet MS/TP BACnet points are writable?

36 of the 120 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 Adveco Lincoln L70 BMS Interface (extension board) BACnet MS/TP BACnet documentation?

The source is Lincoln L70 BMS Interface BACnet Protocol, revision Rev. 1 - 07062023, published free by Adveco at https://adveco.co/wp-content/uploads/2023/06/L70-Lincoln-Extension-BACnet-Protocol-Rev.1.pdf.

What are the minimum BACnet points to integrate the Adveco Lincoln L70 BMS Interface (extension board) BACnet MS/TP?

Start with IV 49 ch_mode_select (CH control mode; 4 = BMS Control); BV 36 ch_bms_demand (CH demand from the BMS (1 = active)); IV 53 dhw_mode_select (DHW control mode; 3 = BMS Control); BV 44 dhw_bms_demand (DHW demand from the BMS); AV 15 ch_master_flow_SP (CH flow setpoint in DI/BMS mode, °C); AV 18 dhw_flow_SP (DHW flow setpoint, °C); AI 13 ch_flow_SP (CH flow setpoint in use); BI 37 ch_demand (CH demand active); BI 39 ges_major_fault (Any major fault); BI 40 ges_minor_fault (Any minor fault).

How do I enable BMS control of the Adveco Lincoln L70 BMS Interface (extension board) BACnet MS/TP?

Can the BMS supply sensor values to the Adveco Lincoln L70 BMS Interface (extension board) BACnet MS/TP?

How do I check these points on the real Lincoln L70 BMS Interface (extension board) BACnet MS/TP?

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.
