Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH EZC zone controller BACnet points list
Updated 12 November 2026
Each EZC zone controller of an older SKH atomiser system is its own BACnet MS/TP device. It carries the zone demand and output, room and duct humidity and temperature readings, occupied, unoccupied, vacant, internal and network setpoints, network humidity and temperature inputs with a timeout, the control mode and source selectors, stage outputs, cutouts and sensor alarms, and a weekly occupancy schedule.
This page lists 121 BACnet objects for the Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH EZC zone controller — 84 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 EZC zone controller
Set MSV 2 Occupancy and BV 2 ZoneMode, choose the control mode (MSV 100) and sources (MSV 101-103). For network control write AV 1 ZoneDemand or the network setpoint and RH (AV 11, AV 13) before the network timeout (AV 102) runs out. Read MSV 1 ZoneState, AV 3 ZoneOutput, AI 4 room RH and the alarm flags.
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 2 | ZoneMode | Zone on/off (1 = on) | Write |
| MV 2 | Occupancy | Occupancy: 1 occ, 2 unocc, 3 vacant, 4 off | Write |
| MV 100 | Cfg_ControlMode | Control mode; 5 = network | Write |
| AV 1 | ZoneDemand | Zone demand from the BMS, % | Write |
| AV 11 | NetworkRHSetpoint | Network RH setpoint | Write |
| AV 13 | NetworkRH | Network room RH from the BMS | Write |
| MV 1 | ZoneState | Zone state | Read |
| AV 3 | ZoneOutput | Zone output, % | Read |
| AI 4 | RoomRH | Room RH | Read |
| BV 30 | AL_GlobalAlarmMask | Global alarm (zone) | Read |
Enable & remote start
BV 2 ZoneMode turns the zone on; MSV 100 Cfg_ControlMode = 5 (Network) hands the demand to the BMS.
Heartbeat & communication loss
AV 102 Cfg_NetworkTimeout (1-15 min) sets how long network values are held; AV 15 counts down and BV 36 AL_NetworkTimeout flags a lapse.
Sensors & values from the BMS
MSV 101 / 102 = Network take room RH and temperature from AV 13 NetworkRH and AV 14 NetworkTemp; MSV 103 = Network takes the setpoint from AV 11 / AV 12.
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
- Network values must be refreshed within Cfg_NetworkTimeout (AV 102, 1-15 min) or BV 36 AL_NetworkTimeout is raised.
- BV 102 Cfg_NetworkControlOverride is a configuration switch; check it during commissioning.

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 pump station is a separate BACnet device with its own object list (see the SKH pump station 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 EZC zone controller 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 SKH (legacy, pre-SKH4) high pressure atomiser - SKH EZC zone controller
How many BACnet points does the Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH EZC zone controller have?
This list has 121 BACnet objects: 8 analog inputs, 1 analog output, 55 analog values, 4 binary inputs, 3 binary outputs, 33 binary values, 2 files, 1 schedule, 13 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 EZC zone controller BACnet points are writable?
84 of the 121 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 EZC zone controller 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 EZC zone controller?
Start with BV 2 ZoneMode (Zone on/off (1 = on)); MV 2 Occupancy (Occupancy: 1 occ, 2 unocc, 3 vacant, 4 off); MV 100 Cfg_ControlMode (Control mode; 5 = network); AV 1 ZoneDemand (Zone demand from the BMS, %); AV 11 NetworkRHSetpoint (Network RH setpoint); AV 13 NetworkRH (Network room RH from the BMS); MV 1 ZoneState (Zone state); AV 3 ZoneOutput (Zone output, %); AI 4 RoomRH (Room RH); BV 30 AL_GlobalAlarmMask (Global alarm (zone)).
How do I enable BMS control of the Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH EZC zone controller?
BV 2 ZoneMode turns the zone on; MSV 100 Cfg_ControlMode = 5 (Network) hands the demand to the BMS.
Does the Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH EZC zone controller need a BACnet heartbeat or have a communication timeout?
AV 102 Cfg_NetworkTimeout (1-15 min) sets how long network values are held; AV 15 counts down and BV 36 AL_NetworkTimeout flags a lapse.
Can the BMS supply sensor values to the Neptronic SKH (legacy, pre-SKH4) high pressure atomiser - SKH EZC zone controller?
MSV 101 / 102 = Network take room RH and temperature from AV 13 NetworkRH and AV 14 NetworkTemp; MSV 103 = Network takes the setpoint from AV 11 / AV 12.
How do I check these points on the real SKH (legacy, pre-SKH4) high pressure atomiser - SKH EZC zone controller?
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.
