AERCO ADMS Smart Water Tempering System BACnet points list
Updated 4 November 2026
The ADMS control module (built by tekmar for AERCO) supports BACnet IP, BACnet MS/TP or Modbus RTU, picked in the BAS menu. The BACnet object list is small: temperatures, pressures, flows, mix ratio, energy, an error code, the recirculation pump relay and one writable DHW target.
This page lists 16 BACnet objects for the AERCO ADMS Smart Water Tempering System — 1 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from AERCO’s own free documentation, linked below.

BMS integration notes: AERCO ADMS Smart Water Tempering System
Set BAS Type to BAC-IP or BAC-MSTP in the Building Automation menu and set the device ID (and MAC/baud for MS/TP). Set BAS Setpoint Max at the control to limit remote changes, then write AV 0 for the mixed outlet target. The rest is monitoring.
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 | DHW Target | Mixed outlet target, °F (capped by AI 10) | Write |
| AI 0 | DHW Temp | Mixed outlet temperature, °F | Read |
| AI 1 | DHW Recirc Temp | Recirculation return temperature, °F | Read |
| AI 11 | Mix % | Mix ratio, % | Read |
| BO 0 | Recirc Pump Relay | Recirculation pump running (read-only) | Read |
| AI 13 | Error Code | Error code, 0-30 | Read |
Enable & remote start
No enable point. With a BAS type selected the BMS can write AV 0; the BAS Setpoint Max setting at the control (default 140 °F, range 80 °F up to the mixed outlet maximum less 10 °F) limits it.
Network setup
- BAS Type: NONE (default), BAC-IP, BAC-MSTP or MODBUS.
- BACnet Device ID 0-4194303, default 1.
- IP: UDP port default 47808; optional foreign device registration (BBMD IP default 127.127.127.127, port 47808, TTL 30-65535 s).
- MS/TP: MAC 0-127 (default 1), baud 9600 default, up to 115200.
- DeviceCommunicationControl password is AERCO1017.
Watch out for
- BO 0 is read-only even though it is an output object.
- No segmentation support per the PICS.

Object ID lookup: AERCO ADMS Smart Water Tempering System point IDs by name
Integration notes
- The PICS lists vendor tekmar Control Systems Ltd., vendor ID 983, model 106902.
- There are no binary inputs; the recirculation pump status is published as a read-only Binary Output (BO 0).
- The manual also prints "Other / ERROR" rows meaning instances not listed return an error; they are not real objects and are left out.
- AV 0 is capped by the BAS Setpoint Max set at the control (read back on AI 10).
- Pressure and flow points need the matching sensors fitted.
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 ADMS Smart Water Tempering System and exports what it actually has to Excel — free. New to BACnet?

Questions about the AERCO ADMS Smart Water Tempering System
How many BACnet points does the AERCO ADMS Smart Water Tempering System have?
This list has 16 BACnet objects: 14 analog inputs, 1 analog value, 1 binary output. The exact set on a given unit depends on its firmware, installed options and configuration.
Which AERCO ADMS Smart Water Tempering System BACnet points are writable?
1 of the 16 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 AERCO ADMS Smart Water Tempering System BACnet documentation?
The source is ADMS Smart Water Tempering System User Guide & Instruction Manual (BAS Integration section) (OMM-0126C), revision 04/09/2026, published free by AERCO at https://www.aerco.com/dfsmedia/0533dbba17714b1ab581ab07a4cbb521/658965-source/638779906930000000/adms-operation-and-maintenance-manual-omm-126.pdf.
What are the minimum BACnet points to integrate the AERCO ADMS Smart Water Tempering System?
Start with AV 0 DHW Target (Mixed outlet target, °F (capped by AI 10)); AI 0 DHW Temp (Mixed outlet temperature, °F); AI 1 DHW Recirc Temp (Recirculation return temperature, °F); AI 11 Mix % (Mix ratio, %); BO 0 Recirc Pump Relay (Recirculation pump running (read-only)); AI 13 Error Code (Error code, 0-30).
How do I enable BMS control of the AERCO ADMS Smart Water Tempering System?
No enable point. With a BAS type selected the BMS can write AV 0; the BAS Setpoint Max setting at the control (default 140 °F, range 80 °F up to the mixed outlet maximum less 10 °F) limits it.
How do I check these points on the real ADMS Smart Water Tempering System?
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.
