Neptronic SKE4 BACnet points list

Updated 28 October 2026

Short answer

The SKE4 is an electric element steam humidifier whose controller has BACnet MS/TP and BACnet IP built in. It publishes a large fixed object list: analog inputs, demand and RH readings, control source selections, network demand and high-limit inputs, service counters, alarms, relays and schedules.

This page lists 187 BACnet objects for the Neptronic SKE4 — 131 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 SKE4

Integration in brief

Pick a network control profile (MSV 28 = ExternNetwork or InternNetwork) or set the demand source MSV 43 to Network, then write the demand to AV 138 (or room RH to AV 106 with a setpoint in AV 107 for internal control). Use MSV 83 to switch the system on/off and watch MSV 60, MSV 64 and BV 46.

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
MV 83	System Power State	System on/off from the BMS	Write
MV 28	Control Profile	Control profile: choose a Network profile	Write
AV 138	Humidity Control Network Demand	Network humidity demand written by the BMS	Command
AV 107	Room RH Setpoint	Occupied room RH setpoint (internal control)	Write
AV 106	Room RH Network Reading	Network room RH reading for internal control	Command
MV 60	Boiler State	Humidifier operating state	Read
AV 149	Boiler Power Output	Actual steam output of the humidifier %	Read
MV 64	Boiler Alarm	Active alarm	Read
BV 46	Network Control State	1 = fault: network control lost (AV 242 timeout)	Write

Enable & remote start

MSV 83 System Power State is writable (1 = Off, 2 = On). Control comes from the source selected by MSV 28 Control Profile or, with the Custom profile, by MSV 43 Humidity Control Demand Source (4 = Network); hard-wired interlock, airflow and high-limit contacts still cut out the unit (MSV 51).

Heartbeat & communication loss

AV 242 Network Timeout (1-900 s) sets how long the humidifier tolerates loss of BACnet control communication before it stops operating; BV 46 Network Control State shows 1 = Fault. Keep refreshing the network demand/readings while any source is set to Network.

Sensors & values from the BMS

Set MSV 33 Room RH Source = Network and write room RH to AV 106; set MSV 38 Supply High Limit Reading Source = Network and write duct RH to AV 122. Setpoints are AV 107 (occupied), AV 108 (unoccupied), AV 109 (vacant) and AV 123 (supply high limit). Direct demand goes to AV 138 and a network high limit to AV 139.

Network setup

MS/TP MAC defaults to 1 (000-254; 128-254 are non-token-passing slaves); baud rate auto-detects (Auto, 9600, 19200, 38400, 76800); Max_Master 127.
Device instance defaults to 153000 + MAC (153001 out of the box) and can be changed from the menu or by writing Device Object_Identifier.
BACnet IP uses UDP 47808 (0xBAC0) by default.
Network/communication settings are in the controller's Integration menu (password 5544); power-cycle after connecting to the network.
Reinitialize Device (warm/cold reset) over BACnet uses the password 'nep'.

Watch out for

MSV 'BACnet Server List Mode' chooses which objects are published (Integrator, Advanced, Factory); objects marked Advanced in the guide, such as the program objects, only show in Advanced mode.
Writing Out_of_Service = True disconnects an object from its physical input so the Present_Value can be overwritten; remember to set it back.
The unit signals alarms through object values only; it does not send BACnet event notifications, so poll or use COV.
COV subscriptions are lost on a power cycle.
Lower Max_Master to the highest MAC on the trunk to speed up MS/TP token passing.
MSV 59 Boiler Request triggers one-off actions (reset alarms, drain, reset counters, fill, water calibration).

Integration notes

Objects and their writable properties are taken from the guide's 'W?' column; Present_Value writable means the BMS can change it.
Units follow the BACnet Server Units setting (Metric or Imperial).

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 SKE4 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 SKE4

How many BACnet points does the Neptronic SKE4 have?

This list has 187 BACnet objects: 11 analog inputs, 2 analog outputs, 75 analog values, 10 binary inputs, 15 binary outputs, 19 binary values, 5 files, 2 schedules, 30 multi-state values, 7 characterstring values, 11 others. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Neptronic SKE4 BACnet points are writable?

131 of the 187 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 SKE4 BACnet documentation?

The source is SKE4 Steam Humidifier BACnet Communication Module User Guide (SKE4-BACnet Guide-230616 (V2.07)), revision 2023-06-16, published free by Neptronic at https://www.neptronic.com/Humidifiers/PDF/SKE4/Manuals/2023/SKE4-BACnet%20Guide-230616%20(V2.07).pdf.

What are the minimum BACnet points to integrate the Neptronic SKE4?

Start with MV 83 System Power State (System on/off from the BMS); MV 28 Control Profile (Control profile: choose a Network profile); AV 138 Humidity Control Network Demand (Network humidity demand written by the BMS); AV 107 Room RH Setpoint (Occupied room RH setpoint (internal control)); AV 106 Room RH Network Reading (Network room RH reading for internal control); MV 60 Boiler State (Humidifier operating state); AV 149 Boiler Power Output (Actual steam output of the humidifier %); MV 64 Boiler Alarm (Active alarm); BV 46 Network Control State (1 = fault: network control lost (AV 242 timeout)).

How do I enable BMS control of the Neptronic SKE4?

Does the Neptronic SKE4 need a BACnet heartbeat or have a communication timeout?

Can the BMS supply sensor values to the Neptronic SKE4?

How do I check these points on the real SKE4?

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.
