Condair RO-E BACnet points list
Updated 28 October 2026
The Condair RO-E makes demineralised water for humidifiers. Its Integrated Controller exposes BACnet IP and MS/TP on-board with status, maintenance and disinfection countdowns, inlet/tank/membrane pressures, permeate quality and flow, valve states and writable tank pressure start/stop limits.
This page lists 24 BACnet objects for the Condair RO-E — 4 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
The RO-E is monitoring-focused: enable BACnet in its Integrated Controller and read status, service status, error code, pressures and permeate quality. The only writable items are the tank pressure start/stop limits and an error/warning reset.
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
- BACnet settings are under Menu > password 8808 > Network > BACnet Settings; the BACnet Protocol parameter ships Off (options MS/TP Master, MS/TP Slave, BACnet/IP) and the controller restarts after changing it.
- Node ID (device instance) defaults to 1001 (range 1-4194303); BACnet IP port defaults to 47808.
- IP addressing defaults to DHCP; if no DHCP server answers the controller falls back to an APIPA 169.254.x.x address.
- Foreign Device registration to a BBMD is Off by default; BBMD port 47808 and re-register time 10 are the factory values.
Watch out for
- Permeate conductivity and drain valve are optional on RO-E and standard on RO-E+; the permeate valve is RO-E+ only.
- AV 10127/10128 set the tank refill start/stop pressures.
- Pressure, temperature and flow units follow the Metric/Imperial setting.

Integration notes
- BACnet is built into the Integrated Controller (RJ45 for BACnet IP, RS485 for MS/TP master or slave); it ships with the BACnet protocol set to Off.
- Factory Node ID (device instance) is 1001 and the MS/TP MAC is 127; BACnet IP uses UDP 47808 and supports registering with a BBMD.
- Some points are RO-E+ only or optional on the RO-E (permeate conductivity, drain valve, permeate valve).
- Pressure, temperature and flow units follow the controller's Metric/Imperial setting.
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 and exports what it actually has to Excel — free. New to BACnet?

Questions about the Condair RO-E
How many BACnet points does the Condair RO-E have?
This list has 24 BACnet objects: 10 analog inputs, 3 analog values, 5 binary inputs, 1 device, 4 multi-state inputs, 1 other. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Condair RO-E BACnet points are writable?
4 of the 24 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 documentation?
The source is BACnet on-board - Addendum manual for installation and operation (DL II, ME II, RS II, RO-E and Vita) (2603582-F), revision 2026-07, published free by Condair at https://www.condair.co.uk/consense/bms-communication-ic-2.0/am_bms_interface_bacnet_on_board_2603582_en.pdf.
What are the minimum BACnet points to integrate the Condair RO-E?
Start with AV 30002 Error/Warning Reset (Clears active errors and warnings); MI 121 RO Device Status (RO operating status); AI 10144 RO Permeate Conductivity (Permeate conductivity (water quality)); AI 10142 RO Tank Pressure (Product water tank pressure); AI 10210 RO Next Disinfection (Days to next disinfection); MI 122 RO Service Status (Maintenance/warning/error status); AI 10020 ErrorWarning Code (Active error or warning code).
How do I check these points on the real Condair RO-E?
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.
