CAREL humiFog Multizone / Multizone Touch / Touch Oil-free - zone controller BACnet points list
Updated 12 November 2026
Short answer
Each humiFog Multizone zone controller can be supervised on its own over BACnet MS/TP or BACnet IP. Its list starts at address 300 and holds the zone's production request and actual production, probe readings, humidity and temperature set points and limits, supervisor request, alarm and warning flags, supervisor on/off and enable commands, zone status, control mode and versions.
This page lists 117 BACnet objects for the CAREL humiFog Multizone / Multizone Touch / Touch Oil-free - zone controller — 48 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 humiFog Multizone / Multizone Touch / Touch Oil-free - zone controller
Integration in brief
Enable supervisor on/off and control for the zone, then switch it with SVOnOff and either write the humidity (or temperature) set point or a production request (SVReq). Monitor zone status, production, probe readings and the alarm and warning 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.

Enable & remote start
SVEnOnOff enables zone on/off from the supervisor and SVEnReg enables zone control from the supervisor; then SVOnOff switches the zone.
Heartbeat & communication loss
Zone warning and alarm objects report a supervisor offline condition (WRO05 / WRO09).
Sensors & values from the BMS
SVReq (AV 331) is the zone production request from the supervisor, used when the zone control mode takes an external request.
Network setup
- Supervisor settings are under Menu > Settings > System > BMS: BMS port address, baud, stop bits, parity, Ethernet IP settings, and BACnet MS/TP station address, max masters, max frames and device instance.
- MS/TP defaults: station address 0, max masters 127, max frames 10, device instance 77000 (range 0-4194302); BMS port default 19200 baud.
- Only one BACnet instance is available: BACnet cannot run on the BMS (RS485) port and the Ethernet port at the same time.
- Each supervisor channel (Menu > Settings > System > Functions > Channel 1-3) is set to Supervisor or Supervisor + Controller with a protocol + port (ModBus BMS/ETH, BACnet BMS/ETH).
Watch out for
- Do not write variables that are not in the tables.
- Values are scaled by the resolution shown (0.1 for most analog values).

Integration notes
- When connected to a zone controller, only that zone's variables are available and addresses always start at 300 (ZoneData_S structure).
- Object type follows the data type column (Real = AV, Bool = BV, integers = PIV). Values are scaled 0.1 where the UoM column says 0.1.
- The Multizone (+0300115EN) and Touch Oil-free (+0300127EN) manuals print the same zone tables.
- Rows printed with access 'OR' are read-only. Units switch between metric and imperial with UoM_SV.
- Source: +0300116EN rel. 1.3 section 9.4.4-9.4.6, pages 92-94 (117 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 humiFog Multizone / Multizone Touch / Touch Oil-free - 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 CAREL humiFog Multizone / Multizone Touch / Touch Oil-free - zone controller
How many BACnet points does the CAREL humiFog Multizone / Multizone Touch / Touch Oil-free - zone controller have?
This list has 117 BACnet objects: 34 analog values, 63 binary values, 20 positive integer values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which CAREL humiFog Multizone / Multizone Touch / Touch Oil-free - zone controller BACnet points are writable?
48 of the 117 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 humiFog Multizone / Multizone Touch / Touch Oil-free - zone controller BACnet documentation?
The source is humiFog Multizone Touch pumping station and zone panel - Commissioning manual (+0300116EN rel. 1.3), revision 2025-10-28, published free by CAREL at https://www.carel.com/documents/10191/0/%2B0300116EN/1990b09e-81eb-47c9-b022-bf575f96bb0f?version=1.3.
What are the minimum BACnet points to integrate the CAREL humiFog Multizone / Multizone Touch / Touch Oil-free - zone controller?
Start with BV 372 ZoneData_S.Z_WorkPar.SVEnOnOff (Enable zone on/off from supervisor); BV 371 ZoneData_S.Z_WorkPar.SVEnReg (Enable zone control from supervisor); BV 373 ZoneData_S.Z_WorkPar.SVOnOff (Zone on/off from supervisor); AV 306 ZoneData_S.Z_WorkPar.GlbSetP_Hum (Zone humidity set point, %rh); AV 331 ZoneData_S.Z_WorkPar.SVReq (Production request from supervisor, %); PIV 300 ZoneData_S.Z_Info.ZoneStatus (Zone status code); AV 301 ZoneData_S.Z_Info.CurrProd (Current zone production); AV 303 ZoneData_S.Z_Info.MainPrb (Main probe reading); BV 369 ZoneData_S.Z_Info.ZoneAlrmPresent (Any zone alarm active); BV 370 ZoneData_S.Z_Info.ZoneWarning (Any zone warning active).
How do I enable BMS control of the CAREL humiFog Multizone / Multizone Touch / Touch Oil-free - zone controller?
SVEnOnOff enables zone on/off from the supervisor and SVEnReg enables zone control from the supervisor; then SVOnOff switches the zone.
Does the CAREL humiFog Multizone / Multizone Touch / Touch Oil-free - zone controller need a BACnet heartbeat or have a communication timeout?
Zone warning and alarm objects report a supervisor offline condition (WRO05 / WRO09).
Can the BMS supply sensor values to the CAREL humiFog Multizone / Multizone Touch / Touch Oil-free - zone controller?
SVReq (AV 331) is the zone production request from the supervisor, used when the zone control mode takes an external request.
How do I check these points on the real humiFog Multizone / Multizone Touch / Touch Oil-free - 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.
