Condair RO-E (BACnet gateway board) BACnet points list
Updated 12 November 2026
The Condair RO-E reverse osmosis unit, which feeds water to Condair humidifiers, can be put on BACnet IP or MS/TP with an optional ProtoCessor gateway board. The virtual device reports RO type, operating and service status, capacity, error code, pressures, permeate quality and flow, maintenance hours and valve states, and lets the BMS set the tank pressure band and reset errors.
This page lists 23 BACnet objects for the Condair RO-E (BACnet gateway board) — 3 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Condair’s own free documentation, linked below.

BMS integration notes: Condair RO-E (BACnet gateway board)
The RO-E list is monitoring only, apart from the tank pressure band and an error reset. Map device status, service status and the error code, plus tank and inlet pressure; watch next maintenance and next disinfection for service planning.
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.

Network setup
- Gateway BACnet IP defaults to 192.168.1.24/24 on boards built from February 2022 (10.232.72.172/16 before); set it in the FS-GUI web page on port 80.
- MS/TP gateways ship as master, MAC 127, 9600 baud, Node_ID (device instance) 1001; change them in the gateway's config.csv.
- FS-GUI login is admin plus the password on the board sticker; the manual recommends changing it and switching to HTTPS.
Watch out for
- Error codes are listed in the RO-E operation manual, not this addendum.
- Pressure, flow and temperature units change with the controller's Imperial/Metric setting.

Integration notes
- These objects belong to the optional gateway board, not the RO-E's BACnet on-board interface; names and instances differ between the two.
- Object names are printed with spaces and with the type as a prefix (for example "MI RO Type"); AI 106 is printed as AI_ROPermeateConductivity.
- Pressure, flow and temperature units follow the Imperial/Metric setting in the RO-E controller.
- Conductivity and the drain valve are standard on the RO-E+ and optional on the RO-E; the permeate valve is RO-E+ only; permeate temperature, flow, outlet and concentrate valves are options.
- The device table gives instance 300 with a pointer to the gateway configuration section; MS/TP gateways default to Node_ID 1001 there.
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 Condair RO-E (BACnet gateway board) and exports what it actually has to Excel — free. New to BACnet?

Questions about the Condair RO-E (BACnet gateway board)
How many BACnet points does the Condair RO-E (BACnet gateway board) have?
This list has 23 BACnet objects: 10 analog inputs, 3 analog values, 5 binary inputs, 1 device, 4 multi-state inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Condair RO-E (BACnet gateway board) BACnet points are writable?
3 of the 23 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 Condair RO-E (BACnet gateway board) BACnet documentation?
The source is Gateway Board for BACnet and LonWorks - Supplemental Installation and Operation Manual (DL II, ME II, RS II and RO-E) (2603584-F), revision 2026-07, published free by Condair at https://www.condair.com/consense/bms-communication-ic-2.0/am_bms_interface_2603584_en.pdf.
What are the minimum BACnet points to integrate the Condair RO-E (BACnet gateway board)?
Start with AV 103 AV Error/Warning Reset (Reset errors and warnings); MI 102 MI RO Device Status (Operating status); AI 104 AI RO Tank Pressure (Tank pressure); AI 103 AI RO Inlet Pressure (Inlet pressure); AI 109 AI RO Next Maintenance (Hours to next maintenance); MI 103 MI RO Service Status (Maintenance/warning/error status); AI 101 AI Error Warning Code (Active error/warning code).
How do I check these points on the real Condair RO-E (BACnet gateway board)?
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.
