Evaporative humidifier · BACnet points list
Neptronic SKV BACnet points list
Updated 28 October 2026
The SKV is a multi-module evaporative humidifier. Its controller speaks BACnet MS/TP and exposes control mode and source selection, network setpoints and readings, a network fallback timeout, and per-module (1-4) demand, state, valve, float and fault objects.
This page lists 277 BACnet objects for the Neptronic SKV — 242 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Neptronic’s own free documentation, linked below.

BMS integration notes: Neptronic SKV
Set MSV 4 ControlMode to Network (or an internal mode with network sources) and write demand to AV 5, or feed room RH via MSV 3 = Network. Turn the system on with BV 116 SystemPower and keep network values fresh inside the fallback timeout (AV 38).
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 |
|---|---|---|---|
| BV 116 | SystemPower | System power on/off | Write |
| MV 4 | ControlMode | Control mode (6 = Network) | Write |
| AV 5 | SystDemand | Demand from the BMS, % (when MSV 4 = Network) | Write |
| AV 16 | SetpointRH | BMS RH setpoint (when MSV 5 = Network) | Write |
| AV 13 | RoomRH | BMS room RH (when MSV 3 = Network) | Write |
| MV 16 | Module1State | Stand-by/drain/fill/ready/alarm state of module 1 | Write |
| AV 1 | SystOutput | Actual system output % | Write |
| BV 118 | AlarmRelay | Closed on any alarm but airflow cutout/service warning | Write |
| BV 121 | NetworkFallbackAlarm | On when network values time out (AV 38) | Write |
Enable & remote start
BV 116 SystemPower: ON = normal operation, OFF = demand inhibited. MSV 4 ControlMode selects an analog input, internal temperature/RH control or Network.
Heartbeat & communication loss
AV 38 NetworkFallbackTimeout (1-15 min) applies whenever at least one control input uses Network as its source; AV 39 counts down and BV 121 NetworkFallbackAlarm turns on when it expires.
Sensors & values from the BMS
Set MSV 3 RoomRHSource or MSV 2 RoomTempSource to Network and write the values from the BMS; MSV 5 SetpointSource = Network uses the external setpoints AV 16 (RH) and AV 17 (temperature).
Network setup
- MS/TP MAC defaults to 000 (000-254; 128-254 are non-token-passing slaves); baud auto-detects (Auto, 9600, 19200, 38400, 76800); Max_Master 127.
- Device instance defaults to 153000 and can be set from the menu or via Device Object_Identifier.
Watch out for
- Older (2018) guide: the W? column marks every object as Present Value, so confirm writability on site.
- Faults that stop a module need a manual reset (BV 95 SystResetAlarms or the Diagnostic menu).
- BV 107 RunWhileServiceAlarm decides whether modules keep running when a service alarm is due.
Neptronic SKV BACnet objects
Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.
Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes
- The guide's W? column lists Present Value for every object, so access here is inferred: inputs read-only, values writable.
- Module 2-4 objects only apply to multi-module systems.
- Temperature units follow the controller's Temperature Units 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 SKV and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.
Questions about the Neptronic SKV
How many BACnet points does the Neptronic SKV have?
This list has 277 BACnet objects: 13 analog inputs, 100 analog values, 13 binary inputs, 121 binary values, 4 files, 2 schedules, 19 multi-state values, 5 others. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Neptronic SKV BACnet points are writable?
242 of the 277 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. The source has no read/write column, so this is inferred from object type.
Where is the official Neptronic SKV BACnet documentation?
The source is SKV Evaporative Humidifier BACnet User Guide, revision 2018-09-05, published free by Neptronic at https://www.neptronic.com/Humidifiers/PDF/skv/20180905/SKV-BACnet-180905.pdf.
What are the minimum BACnet points to integrate the Neptronic SKV?
Start with BV 116 SystemPower (System power on/off); MV 4 ControlMode (Control mode (6 = Network)); AV 5 SystDemand (Demand from the BMS, % (when MSV 4 = Network)); AV 16 SetpointRH (BMS RH setpoint (when MSV 5 = Network)); AV 13 RoomRH (BMS room RH (when MSV 3 = Network)); MV 16 Module1State (Stand-by/drain/fill/ready/alarm state of module 1); AV 1 SystOutput (Actual system output %); BV 118 AlarmRelay (Closed on any alarm but airflow cutout/service warning); BV 121 NetworkFallbackAlarm (On when network values time out (AV 38)).
How do I enable BMS control of the Neptronic SKV?
BV 116 SystemPower: ON = normal operation, OFF = demand inhibited. MSV 4 ControlMode selects an analog input, internal temperature/RH control or Network.
Does the Neptronic SKV need a BACnet heartbeat or have a communication timeout?
AV 38 NetworkFallbackTimeout (1-15 min) applies whenever at least one control input uses Network as its source; AV 39 counts down and BV 121 NetworkFallbackAlarm turns on when it expires.
Can the BMS supply sensor values to the Neptronic SKV?
Set MSV 3 RoomRHSource or MSV 2 RoomTempSource to Network and write the values from the BMS; MSV 5 SetpointSource = Network uses the external setpoints AV 16 (RH) and AV 17 (temperature).
How do I check these points on the real SKV?
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.
