Condair Condair DL (BACnet gateway board) BACnet points list
Updated 28 October 2026
Older or retrofit Condair DL units can reach BACnet IP or MS/TP through an optional ProtoCessor gateway board that maps the controller's Modbus data to BACnet objects. The virtual device exposes status, Ag-Ion hygiene data, pressures, PI settings, remote flush/wash-over commands and valve states.
This page lists 39 BACnet objects for the Condair Condair DL (BACnet gateway board) — 7 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 Condair DL (BACnet gateway board)
Configure the DL controller for Modbus RTU (address 10, even, 9600) with Signal Source = Modbus, set the gateway's BACnet IP or MS/TP parameters, then write demand or RH to AO 1. Watch BI 14 to confirm the gateway still sees the humidifier.
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 |
|---|---|---|---|
| AO 1 | AO_RemRHorDem | Demand or measured RH from the BMS | Command |
| AV 1 | AV_SetPointHum | Humidity setpoint used in RH P/PI mode | Write |
| MI 1 | MI_HumStatus | Operating status | Read |
| AI 6 | AI_ActCapHum | Actual spray water output | Read |
| BI 14 | BI_Connection | Gateway-to-humidifier node status | Read |
| MI 2 | MI_ServStatus | Maintenance/fault status | Read |
| AI 1 | AI_ErrorCode | Active error code | Read |
Enable & remote start
Set Control Settings (password 0335) > Signal Source to Modbus, choose the Control Mode (Demand, RH P or RH PI), and set the controller's Modbus RTU parameters to match the gateway.
Heartbeat & communication loss
Controller BMS Timeout (1-300 s, default 300 s): if the control signal is not updated within the timeout, warning W35 BMS Timeout is raised and humidification stops until a valid signal returns. The gateway only forwards the control value to the humidifier when it changes.
Sensors & values from the BMS
In Demand mode the BMS writes the required output (0-100 %) to the AO 1. In RH P or RH PI mode the BMS writes the measured humidity there and the controller's own setpoint, P-band and I-time AVs do the control. Do not connect a hard-wired demand or sensor signal while the BACnet signal is used.
Network setup
- Integrated Controller Communication submenu (password 0335): Modbus/RTU, address 10, even parity, 9600 baud, MSR first; disable the controller's own BACnet function.
- Gateway factory settings: BACnet IP device instance DL 300, ME 410, RS 710 (EL 220); MS/TP 9600 baud, MAC 127, Node_ID 1001.
- Gateway IP defaults to 192.168.1.24/24 for boards built from February 2022 (10.232.72.172/16 before); configure via the FS-GUI web page on port 80.
- Device instance, network number (default 101) and MS/TP MAC are edited in the gateway's config.csv.
Watch out for
- Because the gateway only passes the control value on when it changes, rewriting an identical value may not refresh the controller's BMS timeout; the manual does not describe a workaround.
- Object names and instances differ from the BACnet on-board interface of the same humidifier; do not reuse an on-board mapping.
- Capacity, pressure and temperature units follow the controller's Metric/Imperial setting.

Integration notes
- These objects belong to the optional ProtoCessor (FieldServer) BACnet/LonWorks gateway board, not the BACnet on-board interface; object names and instances differ between the two.
- Gateway defaults: IP 192.168.1.24 (boards shipped from February 2022; earlier boards 10.232.72.172), network number 101, MS/TP MAC 127 and MS/TP Node_ID 1001; settings are edited in the gateway's config.csv via its web GUI.
- The gateway talks to the Integrated Controller over Modbus RTU, so the controller signal source is set to Modbus (not BACnet) and its own BACnet on-board function must be Off.
- Capacity, pressure and temperature 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. Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the Condair DL (BACnet gateway board) and exports what it actually has to Excel — free. New to BACnet?

Questions about the Condair Condair DL (BACnet gateway board)
How many BACnet points does the Condair Condair DL (BACnet gateway board) have?
This list has 39 BACnet objects: 14 analog inputs, 1 analog output, 6 analog values, 14 binary inputs, 1 device, 3 multi-state inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Condair Condair DL (BACnet gateway board) BACnet points are writable?
7 of the 39 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 Condair DL (BACnet gateway board) BACnet documentation?
The source is Gateway Board for BACnet and LonWorks - Supplemental Installation and Operation Manual (2585293-L), revision 2022-02, published free by Condair at https://www.condair.com/consense/bms-communication-ic-1.0/am_bms_interface_2585293_en_condairltd.pdf.
What are the minimum BACnet points to integrate the Condair Condair DL (BACnet gateway board)?
Start with AO 1 AO_RemRHorDem (Demand or measured RH from the BMS); AV 1 AV_SetPointHum (Humidity setpoint used in RH P/PI mode); MI 1 MI_HumStatus (Operating status); AI 6 AI_ActCapHum (Actual spray water output); BI 14 BI_Connection (Gateway-to-humidifier node status); MI 2 MI_ServStatus (Maintenance/fault status); AI 1 AI_ErrorCode (Active error code).
How do I enable BMS control of the Condair Condair DL (BACnet gateway board)?
Set Control Settings (password 0335) > Signal Source to Modbus, choose the Control Mode (Demand, RH P or RH PI), and set the controller's Modbus RTU parameters to match the gateway.
Does the Condair Condair DL (BACnet gateway board) need a BACnet heartbeat or have a communication timeout?
Controller BMS Timeout (1-300 s, default 300 s): if the control signal is not updated within the timeout, warning W35 BMS Timeout is raised and humidification stops until a valid signal returns. The gateway only forwards the control value to the humidifier when it changes.
Can the BMS supply sensor values to the Condair Condair DL (BACnet gateway board)?
In Demand mode the BMS writes the required output (0-100 %) to the AO 1. In RH P or RH PI mode the BMS writes the measured humidity there and the controller's own setpoint, P-band and I-time AVs do the control. Do not connect a hard-wired demand or sensor signal while the BACnet signal is used.
How do I check these points on the real Condair DL (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.
