Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH pump station BACnet points list
Updated 12 November 2026
The older SKH high pressure atomiser shows up on BACnet MS/TP as a pump station device plus one device per EZC zone controller. The pump station device carries the system mode, pump state and demand, zone capacity, pump inlet and outlet pressure and temperature, alarm relay outputs and a long list of pump and communication alarms, plus simulation and inactivity-drain settings.
This page lists 68 BACnet objects for the Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH pump station — 20 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 SKH (legacy, pre-SKH4) high pressure atomiser - SKH pump station
Turn the system on with BV 1 SystemMode and read MSV 1 PumpState, AV 1 PumpDemand and the alarm flags (BV 50/51 service, BV 52 pump global alarm). Humidity control itself is done per zone on the EZC devices.
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.

Enable & remote start
BV 1 SystemMode switches the system on or off.
Network setup
- Baud rate and device instance can be automatic: the humidifier sets its device instance to 153000 + MAC address; the MAC (0-254) is set from the menu.
- Max_Master defaults to 127; lower it for a faster MS/TP trunk.
Watch out for
- Simulation objects (AV 3-8, BV 2-3) are for testing; leave them alone in normal operation.

Integration notes
- Objects are grouped as Integrator, Integrator configuration and Advanced; MSV Cfg_ObjectListMode chooses which groups the device shows (Integrator, Advanced or Factory).
- Access: "Present Value" in the W? column is listed as writable, "Out of Service" (only the out-of-service property is writable) as read-only; commandable BOs are marked C.
- Out-of-service is cleared automatically after 15 minutes by default (Device proprietary property #1002).
- The zone controllers are separate BACnet devices with their own object list (see the SKH EZC list).
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 SKH (legacy, pre-SKH4) high pressure atomiser - SKH pump station and exports what it actually has to Excel — free.

Questions about the Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH pump station
How many BACnet points does the Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH pump station have?
This list has 68 BACnet objects: 1 analog input, 1 analog output, 20 analog values, 3 binary outputs, 34 binary values, 4 files, 4 multi-state values, 1 other. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH pump station BACnet points are writable?
20 of the 68 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 Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH pump station BACnet documentation?
The source is High Pressure Atomiser SKH Series BACnet User Guide (SKH-BACnet Guide-210104), revision 2021-01-04, published free by Neptronic at https://www.neptronic.com/Humidifiers/PDF/SKH/20210107/SKH-BACnet%20Guide-210104.pdf.
What are the minimum BACnet points to integrate the Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH pump station?
Start with BV 1 SystemMode (System on/off (1 = on)); MV 1 PumpState (Pump state (stand-by, pressurizing, ready ...)); AV 1 PumpDemand (Pump demand, %); BV 7 WaterPressureState (Water pressure ready); AV 216 PumpOutputPressure (Pump output pressure, kPa); BO 1 AlarmRelay (Alarm relay (closed on alarm)); BV 52 AL_PumpGlobalAlarmMask (Pump global alarm); BV 51 AL_ServiceAlarm (Service alarm).
How do I enable BMS control of the Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH pump station?
BV 1 SystemMode switches the system on or off.
How do I check these points on the real SKH (legacy, pre-SKH4) high pressure atomiser - SKH pump station?
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.
