CAREL gaSteam (UG) gas-fired humidifier BACnet points list

Updated 4 November 2026

Short answer

gaSteam is CAREL's gas-fired steam humidifier with a built-in controller and web server. BACnet MS/TP (on the BMS RS485 port) and BACnet IP (on the Ethernet port) are built in; only one of the two can be active at a time. The object list covers set points, probe readings, production, burner and fan data, scheduler settings, Main/Secondary data and one BV per alarm.

This page lists 350 BACnet objects for the CAREL gaSteam (UG) gas-fired humidifier — 350 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from CAREL’s own free documentation, linked below.

BMS integration notes: CAREL gaSteam (UG) gas-fired humidifier

Integration in brief

Enable BACnet on the Ethernet port (Eh06, on by default) or on the BMS port (Eh01 protocol BACnet plus Eh03), and set the device instance on Eh04. Then enable On/Off and control from supervisor on Eh07/Eh08. Start and stop the unit with OnBySV (BV 0) and send the production request on SV_PwrReq (AV 73), or let the unit run its own humidity control with the set point on AV 1. Monitor OnOffStatus, UnitStatus, current production and the alarm summary BVs.

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 0	OnBySV	Unit on/off from the BMS	Write
AV 73	SV_PwrReq	Production request from the BMS, 0-100 %	Write
AV 1	GlbSetP_Hum	Humidity set point, %RH (own probe control)	Write
BV 35	OnOffStatus	Unit on/off status	Write
PIV 57	UnitStatus	Operating state code	Write
AV 31	MainPrb	Main probe reading	Write
AV 34	CurrProdPh	Current steam production, kg/h	Write
BV 38	CurrBlkAlrm.IsPresent	At least one alarm active	Write
BV 37	CurrBlkAlrm.IsBlocker	Non-resettable alarm active	Write

Enable & remote start

On screens Eh07/Eh08 (Installer menu) select the supervisor port and enable 'On/Off signal from supervisor' and 'control from supervisor'; on the BMS port the Eh01 settings 'On/Off from SV' and 'Control from SV' do the same. Without them the unit ignores the supervisor on/off and production request.

Heartbeat & communication loss

Eh08 can enable a supervisor-offline alarm (ALP21, BV 135) with an activation delay. The manual does not say what the unit does with its output when the supervisor goes offline.

Sensors & values from the BMS

With control from supervisor the BMS sends the production request on SV_PwrReq (AV 73) instead of the unit using a probe. Up to four CAREL wireless probes can also feed the unit (WirelessPrbVal AI objects).

Network setup

Device instance default 77000 (screen Eh04).
BACnet MS/TP on the BMS port: Eh03 sets the MAC address (default 0), max masters (127) and max info frames (10); Eh02 sets the baud rate (default 19200).
For BACnet MS/TP the manual says to set Eh06 as well as Eh03 (BACnet on the Ethernet port is enabled by default).
BACnet IP on the Ethernet port is enabled by default on Eh06; the unit's default IP is 192.168.0.1/24 with DHCP off (Eh05).
Only one BACnet instance exists, so BACnet cannot run on the BMS port and the Ethernet port at the same time.

Watch out for

Every object is listed RW; don't write to readings, status or alarm objects.
Scheduler, probe range and drain settings (AV 15-29, PIV 10-28, BV 161-166) are configuration; avoid cyclic writes.
SV_Command (PIV 36) resets alarms (1) or cylinder hours (2); it is a one-shot command, not a value to hold.

Integration notes

The manual marks every object RW, including readings and alarm flags; treat probe readings, status and alarm objects as read-only in practice.
Objects ending in _Secondary or _S, and the NetStatus/Alrm_NetUnit objects, only carry data in Main/Secondary or networked installations; the third burner/fan objects (_3, MB_3) apply to the largest models.
Analog engineering units are listed in SI (°C, kg/h); the UoM object (PIV 29) switches between international and imperial units.
Status objects marked with a footnote in the manual (UnitStatus, NetStatus, fan status) carry the state codes shown in the states column.
Source table: 15.1.3 'Table of Bacnet variables', manual pages 107-113 (350 objects).

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 gaSteam (UG) gas-fired humidifier 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 CAREL gaSteam (UG) gas-fired humidifier

How many BACnet points does the CAREL gaSteam (UG) gas-fired humidifier have?

This list has 350 BACnet objects: 8 analog inputs, 62 analog values, 150 binary values, 4 integer values, 126 positive integer values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which CAREL gaSteam (UG) gas-fired humidifier BACnet points are writable?

350 of the 350 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 CAREL gaSteam (UG) gas-fired humidifier BACnet documentation?

The source is gaSteam - UG Gas-fired humidifier - User manual (+0300122EN rel. 1.4), revision 2026-02-26, published free by CAREL at https://www.carel.com/documents/10191/0/%2B0300122EN/b5f100a2-099e-475f-a2d6-26bd03b55518?version=1.5.

What are the minimum BACnet points to integrate the CAREL gaSteam (UG) gas-fired humidifier?

Start with BV 0 OnBySV (Unit on/off from the BMS); AV 73 SV_PwrReq (Production request from the BMS, 0-100 %); AV 1 GlbSetP_Hum (Humidity set point, %RH (own probe control)); BV 35 OnOffStatus (Unit on/off status); PIV 57 UnitStatus (Operating state code); AV 31 MainPrb (Main probe reading); AV 34 CurrProdPh (Current steam production, kg/h); BV 38 CurrBlkAlrm.IsPresent (At least one alarm active); BV 37 CurrBlkAlrm.IsBlocker (Non-resettable alarm active).

How do I enable BMS control of the CAREL gaSteam (UG) gas-fired humidifier?

Does the CAREL gaSteam (UG) gas-fired humidifier need a BACnet heartbeat or have a communication timeout?

Eh08 can enable a supervisor-offline alarm (ALP21, BV 135) with an activation delay. The manual does not say what the unit does with its output when the supervisor goes offline.

Can the BMS supply sensor values to the CAREL gaSteam (UG) gas-fired humidifier?

How do I check these points on the real gaSteam (UG) gas-fired humidifier?

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.
