Armstrong International HumidiClean HC-6000 series (HC-6100/6300/6500/6700) BACnet points list
Updated 4 November 2026
The HumidiClean HC-6000 speaks Modbus RTU natively; BACnet IP or BACnet MS/TP comes through a FieldServer ProtoNode gateway set up with the HC6000 profile. The BACnet list has binary inputs for valves and contactors, binary values for sensor options, analog inputs for status, run timers and temperatures, and analog values for set points, timers, run mode and network control level.
This page lists 59 BACnet objects for the Armstrong International HumidiClean HC-6000 series (HC-6100/6300/6500/6700) — 33 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Armstrong International’s own free documentation, linked below.

BMS integration notes: Armstrong International HumidiClean HC-6000 series (HC-6100/6300/6500/6700)
Connect the ProtoNode gateway, pick the HC6000 BACnet profile in its web configurator and give it the humidifier's Modbus node ID. On the humidifier set Network Control to the level the BMS needs. To run the unit from a BMS demand, enable the network, set Sensor Select (BV 2) to humidistat and write 0-100 % demand. Monitor run status, steam output, water level and the failure code.
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 7 | Run mode | Run mode: 0 steam gen, 3 unit stop | Write |
| AV 28 | NETWORK CONTROL | Network control level (monitor ... full control) | Write |
| AV 2 | Set RH / Demand | Humidity set point or % demand from the BMS | Write |
| BV 2 | Sensor select | 0 = humidistat (demand) input, 1 = RH sensor | Write |
| AI 4 | Run status | Operating state code | Read |
| AI 2 | Steam Output | Steam output, kg/h | Read |
| AI 1 | Desired RH / Demand | Set point or demand in use | Read |
| AI 3 | Water level | Water level state | Read |
| AI 18 | Failure | Active failure code | Read |
Enable & remote start
In the humidifier Setup menu set Network Control to Monitor, Hstat (local humidistat), Sensor (local sensors) or Full; only Full lets the network make all control changes. For BMS demand control the manual says to verify the network is enabled and Sensor Select is humidistat, then write the 0-100 % demand.
Sensors & values from the BMS
The BMS can send a 0-100 % demand instead of a local humidistat or RH sensor. The manual says to write it to a BACnet analog output; the BACnet table itself has no AO, and the matching Modbus register (40002) is 'Set RH / Demand', which is AV 2 here.
Network setup
- ProtoNode gateway default IP 192.168.1.24/24; configure through its web configurator (Protocol Selector, then add the HC6000 profile with the humidifier's node ID).
- Humidifier Modbus side: Comm Address default 1, 9600 baud, even parity, Network Mode = Modbus.
- Set 'BACnet Virtual Server Nodes' to Yes only when several humidifiers share one ProtoNode.
Watch out for
- The table lists failure codes 1-10 for AI 18 but prints no code for the no-failure state.
- AV 21-26 are debug/test timers; don't write them in normal operation.
- Timer values come as hour and minute pairs (e.g. AI 7 + AI 8); combine them for a total time.

Integration notes
- Source: Table 49-1 'BACnet Variant List', manual page 50 (59 objects). The table gives only a description per object, not a BACnet object name, so the description is used as the name here. Object names on a real ProtoNode gateway may differ; match points by type and instance.
- AV 21-26 are marked debug only in the manual.
- Times are split across two objects (hours part and minutes part), e.g. AI 5/6 bed life and AI 7/8 run time.
- Temperatures are listed in °C.
- The ProtoNode gateway's default IP is 192.168.1.24; its DIP switches select the profile (PSP or Modbus RTU to BACnet IP/MS/TP HC6000).
- The manual prints no revision date; 2023-04 is inferred from the '539D-EN V2.1 4-23' code on the back cover.
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 HumidiClean HC-6000 series (HC-6100/6300/6500/6700) and exports what it actually has to Excel — free.

Questions about the Armstrong International HumidiClean HC-6000 series (HC-6100/6300/6500/6700)
How many BACnet points does the Armstrong International HumidiClean HC-6000 series (HC-6100/6300/6500/6700) have?
This list has 59 BACnet objects: 20 analog inputs, 28 analog values, 6 binary inputs, 5 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Armstrong International HumidiClean HC-6000 series (HC-6100/6300/6500/6700) BACnet points are writable?
33 of the 59 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 Armstrong International HumidiClean HC-6000 series (HC-6100/6300/6500/6700) BACnet documentation?
The source is HumidiClean Humidifiers Series HC-6100/6300/6500/6700 - Installation, Operation and Maintenance Instructions (539D-EN V2.1), revision 2023-04, published free by Armstrong International at https://armstronginternational.com/wp-content/uploads/IOM_HC6000_Humidiclean_539_EN.pdf.
What are the minimum BACnet points to integrate the Armstrong International HumidiClean HC-6000 series (HC-6100/6300/6500/6700)?
Start with AV 7 Run mode (Run mode: 0 steam gen, 3 unit stop); AV 28 NETWORK CONTROL (Network control level (monitor ... full control)); AV 2 Set RH / Demand (Humidity set point or % demand from the BMS); BV 2 Sensor select (0 = humidistat (demand) input, 1 = RH sensor); AI 4 Run status (Operating state code); AI 2 Steam Output (Steam output, kg/h); AI 1 Desired RH / Demand (Set point or demand in use); AI 3 Water level (Water level state); AI 18 Failure (Active failure code).
How do I enable BMS control of the Armstrong International HumidiClean HC-6000 series (HC-6100/6300/6500/6700)?
In the humidifier Setup menu set Network Control to Monitor, Hstat (local humidistat), Sensor (local sensors) or Full; only Full lets the network make all control changes. For BMS demand control the manual says to verify the network is enabled and Sensor Select is humidistat, then write the 0-100 % demand.
Can the BMS supply sensor values to the Armstrong International HumidiClean HC-6000 series (HC-6100/6300/6500/6700)?
The BMS can send a 0-100 % demand instead of a local humidistat or RH sensor. The manual says to write it to a BACnet analog output; the BACnet table itself has no AO, and the matching Modbus register (40002) is 'Set RH / Demand', which is AV 2 here.
How do I check these points on the real HumidiClean HC-6000 series (HC-6100/6300/6500/6700)?
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.
