Belimo Gas monitors 22G (CO, NO2, CO2, refrigerant and others) BACnet points list

Updated 12 November 2026Unofficial source

Short answer

Belimo 22G gas monitors measure one or two gases and drive local relays and alarms. The -A and -B models have a BACnet MS/TP port that serves the local gas readings, ambient temperature, an auxiliary input and the alarm/relay states. With menu setting 46 = 2 one monitor also acts as a gateway and publishes the gas readings of every monitor on its CAN bus.

This page lists 7 BACnet objects for the Belimo Gas monitors 22G (CO, NO2, CO2, refrigerant and others) — 3 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Belimo’s documentation hosted by ZOT Supply, not by Belimo itself, so treat it as unofficial.

BMS integration notes: Belimo Gas monitors 22G (CO, NO2, CO2, refrigerant and others)

Integration in brief

Turn on BACnet with menu setting 46, set the MS/TP address, baud and device instance at the keypad, then read the gas readings and the three alarm objects. Use setting 46 = 2 on one -A or -B monitor to bring a whole CAN bus network into the BMS.

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.

Integration notes

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 Gas monitors 22G (CO, NO2, CO2, refrigerant and others) and exports what it actually has to Excel — free.

Questions about the Belimo Gas monitors 22G (CO, NO2, CO2, refrigerant and others)

How many BACnet points does the Belimo Gas monitors 22G (CO, NO2, CO2, refrigerant and others) have?

This list has 7 BACnet objects: 3 analog values, 1 binary input, 3 binary outputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Belimo Gas monitors 22G (CO, NO2, CO2, refrigerant and others) BACnet points are writable?

3 of the 7 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 Belimo Gas monitors 22G (CO, NO2, CO2, refrigerant and others) BACnet documentation?

Belimo does not publish it on its own website. This list comes from Belimo Gas Monitors Operating Manual, 6.2 PICS: BACnet MS/TP, revision 04/26, a copy hosted by ZOT Supply at https://www.zotsupply.com/content/PDFs/Belimo/Gas%20Monitoring/belimo_gas-monitor_operations-manual_en-us.pdf. Ask Belimo or its representative for the current revision.

What are the minimum BACnet points to integrate the Belimo Gas monitors 22G (CO, NO2, CO2, refrigerant and others)?

Start with AV 0 Gas Reading 1 (Gas reading, sensor A); AV 1 Gas Reading 2 (Gas reading, sensor B (dual-gas models)); BO 0 Relay 1 / Alarm L1 (Alarm 1 / relay 1 state); BO 1 Relay 2 / Alarm L2 (Alarm 2 / relay 2 state); BO 2 Alarm 3 (Alarm 3 state).

How do I enable BMS control of the Belimo Gas monitors 22G (CO, NO2, CO2, refrigerant and others)?

Menu setting 46: 0 = BACnet off, 1 = BACnet on, 2 = BACnet on plus all CAN bus gas readings.

How do I check these points on the real Gas monitors 22G (CO, NO2, CO2, refrigerant and others)?

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.
