Watts IntelliStation 2 digital mixing station BACnet points list
Updated 4 November 2026
IntelliStation 2 is a Powers (Watts) electronic DHW mixing station. Its control speaks BACnet MS/TP or BACnet IP (or Modbus RTU), chosen in the BAS menu. The object list is short: temperatures, pressures, flows, valve position, energy, an error code, recirculation pump and isolation valve status, and one writable mixed outlet setpoint.
This page lists 18 BACnet objects for the Watts IntelliStation 2 digital mixing station — 1 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Watts’s own free documentation, linked below.

BMS integration notes: Watts IntelliStation 2 digital mixing station
Pick BACnet MS/TP or BACnet IP as BAS Type at the control and set the device ID (plus MAC and baud for MS/TP, or port and BBMD for IP). Set Remote Setpoint Max at the control to cap what the BMS may write, then write AV 0 for the outlet temperature. Everything else is read-only 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 | Mixed Outlet Setpoint | Mixed outlet setpoint, °F (capped by AI 10) | Write |
| AI 0 | Mixed Outlet Temperature | Mixed outlet temperature, °F | Read |
| AI 1 | Recirc Return Temperature | Recirculation return temperature, °F | Read |
| AI 11 | Valve Position | Mixing valve position, % | Read |
| BI 0 | Recirc Pump 1 | Recirculation pump 1 running | Read |
| AI 13 | Error Code | Active error or alert code | Read |
Enable & remote start
No separate enable point. Selecting a BAS Type in the BAS menu exposes the Remote Setpoint Max setting, which caps the setpoint the BMS can write to AV 0.
Network setup
- BAS Type: Off, Modbus RTU, BACnet MS/TP or BACnet IP.
- Device ID 0-4194302 (both transports).
- MS/TP: MAC 0-127, baud 9600-115200, plus a user-defined BACnet name.
- IP: UDP port 0-65535; optional BBMD foreign device registration with IP, port and time.
- DeviceCommunicationControl password is Powers1164.
Watch out for
- The manual warns that outlet temperatures above 110 °F need point-of-use mixing valves; set Remote Setpoint Max with that in mind.
- No segmentation support per the PICS.

Integration notes
- Published under the Powers brand (Watts); the PICS lists vendor Powers Control Systems Ltd., vendor ID 834.
- Pressure, flow and some temperature points need the matching sensor options fitted.
- AV 0 is limited to 60 °F up to the Remote Setpoint Max set at the control (read back on AI 10).
- AI 13 returns a numeric error/alert code; the manual lists codes for sensor, pressure, flow, network and Wi-Fi faults.
- Temperatures are in °F.
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 IntelliStation 2 digital mixing station and exports what it actually has to Excel — free.

Questions about the Watts IntelliStation 2 digital mixing station
How many BACnet points does the Watts IntelliStation 2 digital mixing station have?
This list has 18 BACnet objects: 14 analog inputs, 1 analog value, 3 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Watts IntelliStation 2 digital mixing station BACnet points are writable?
1 of the 18 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 Watts IntelliStation 2 digital mixing station BACnet documentation?
The source is IntelliStation 2 Installation, Operation, and Maintenance Manual (IOM-P-IntelliStation2), revision 2526, published free by Watts at https://www.watts.com/dfsmedia/0533dbba17714b1ab581ab07a4cbb521/650378-source/638962952400000000/iom-p-intellistation2-2414.pdf.
What are the minimum BACnet points to integrate the Watts IntelliStation 2 digital mixing station?
Start with AV 0 Mixed Outlet Setpoint (Mixed outlet setpoint, °F (capped by AI 10)); AI 0 Mixed Outlet Temperature (Mixed outlet temperature, °F); AI 1 Recirc Return Temperature (Recirculation return temperature, °F); AI 11 Valve Position (Mixing valve position, %); BI 0 Recirc Pump 1 (Recirculation pump 1 running); AI 13 Error Code (Active error or alert code).
How do I enable BMS control of the Watts IntelliStation 2 digital mixing station?
No separate enable point. Selecting a BAS Type in the BAS menu exposes the Remote Setpoint Max setting, which caps the setpoint the BMS can write to AV 0.
How do I check these points on the real IntelliStation 2 digital mixing station?
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.
