Berner AIR air curtain (WCA) BACnet points list
Updated 4 November 2026
The Berner AIR WCA interface puts a Berner air curtain on BACnet IP as an application specific controller (B-ASC). It exposes 11 objects: the mode, fan speed and time delay commands, a weekly operating-hours schedule, door status and door-open count, an operating status, and on heated models a temperature setpoint and door temperature in both °F and °C.
This page lists 11 BACnet objects for the Berner AIR air curtain (WCA) — 6 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Berner’s own free documentation, linked below.

BMS integration notes: Berner AIR air curtain (WCA)
Write MV 1 Mode (Off/On/Auto/Comfort+) and PIV 2 FanSpeed, and on heated models the setpoint AV 1 (°F) or AV 2 (°C). The SCH 1 OperatingHours schedule drives BI 2 OperatingStatus. Read BI 1 DoorStatus and the door temperature.
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 1 | Mode | Mode: 1 off, 2 on, 3 auto, 4 Comfort+ | Write |
| PIV 2 | FanSpeed | Fan speed command | Write |
| AV 1 | TargetTemperatureFahrenheit | Heat setpoint, 34-90 °F (heated models) | Write |
| BI 2 | OperatingStatus | Operating per schedule | Read |
| BI 1 | DoorStatus | Door open (active) or closed | Read |
| AI 1 | TemperatureFahrenheit | Door temperature, °F (heated models) | Read |
Enable & remote start
MV 1 Mode selects Off (1), On (2), Auto (3) or Comfort+ (4); the number of available states depends on the model.
Network setup
- BACnet IP, also as a foreign device.
- SCH 1 OperatingHours defaults to 24/7.
Watch out for
- Most objects go Out_Of_Service when the WCA loses its IntelliSwitch connection.
- AV 1 (°F) and AV 2 (°C) are both the temperature setpoint; map the one in your BMS units.

Object ID lookup: Berner AIR air curtain point IDs by name
Integration notes
- From the PICS object blocks; each object's present value is marked RO or RW.
- AV 1-2 and AI 1-2 exist on heated models only.
- The number of Mode states (2-4) and the fan speed maximum (1, 2, 3 or 10) depend on the air curtain model.
- Most objects report Out_Of_Service = true when the WCA is not connected to the IntelliSwitch.
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 Berner AIR air curtain (WCA) and exports what it actually has to Excel — free. New to BACnet?

How many BACnet points does the Berner AIR air curtain (WCA) have?
This list has 11 BACnet objects: 2 analog inputs, 2 analog values, 2 binary inputs, 1 schedule, 1 multi-state value, 3 positive integer values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Berner AIR air curtain (WCA) BACnet points are writable?
6 of the 11 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 Berner AIR air curtain (WCA) BACnet documentation?
The source is Berner AIR BACnet PICS (Berner WCA), revision 2024-03-28, published free by Berner at https://berner.com/wp-content/uploads/2025/05/Berner-AIR-BACnet-PICS-WCA.pdf.
What are the minimum BACnet points to integrate the Berner AIR air curtain (WCA)?
Start with MV 1 Mode (Mode: 1 off, 2 on, 3 auto, 4 Comfort+); PIV 2 FanSpeed (Fan speed command); AV 1 TargetTemperatureFahrenheit (Heat setpoint, 34-90 °F (heated models)); BI 2 OperatingStatus (Operating per schedule); BI 1 DoorStatus (Door open (active) or closed); AI 1 TemperatureFahrenheit (Door temperature, °F (heated models)).
How do I enable BMS control of the Berner AIR air curtain (WCA)?
MV 1 Mode selects Off (1), On (2), Auto (3) or Comfort+ (4); the number of available states depends on the model.
How do I check these points on the real Berner AIR air curtain (WCA)?
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.
