WOLF WRS-K air handling unit controller - BACnet interface BACnet points list
Updated 7 November 2026
The BACnet interface card for WOLF's WRS-K air-handling controller gives BACnet IP (or BACnet Ethernet) access to the unit. It publishes fixed binary and analog values: operating states and outputs, temperatures, humidity, pressures and airflows, active special modes, one binary value per alarm, and a write section with BMS setpoints, setpoint offsets, the operating mode, BMS outdoor/room temperature, an electric heater power limit and remote alarm reset.
This page lists 198 BACnet objects for the WOLF WRS-K air handling unit controller - BACnet interface — 27 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from WOLF’s own free documentation, linked below.

BMS integration notes: WOLF WRS-K air handling unit controller - BACnet interface
Set AV 1006 Operation_Mode to 2 (BMS operation) and write the BMS setpoints (AV 15 temperature, AV 16/17 fan speeds or AV 1015/1016 pressure, AV 1014 fan step). In manual or weekly-program mode, adjust with the Offset objects instead. Read BV 5 Status_AHU, the supply and room temperatures, and BV 1 Alarm_General plus the individual alarm 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 |
|---|---|---|---|
| AV 1006 | Operation_Mode | Operating mode: 0 manual, 1 weekly program, 2 BMS | Write |
| AV 1014 | Setpoint_Fan_Step_BMS | Unit on/off in BMS mode: 1 = off, 2 = on | Write |
| AV 15 | Setpoint_Temperature_BMS | Temperature setpoint from the BMS, °C | Write |
| AV 16 | Setpoint_Speed_SUP_BMS | Supply fan speed setpoint from the BMS, % | Write |
| AV 17 | Setpoint_Speed_ETA_BMS | Extract fan speed setpoint from the BMS, % | Write |
| BV 90 | Alarm_Reset_BMS | Remote alarm reset (enable in service menu) | Write |
| BV 5 | Status_AHU | Unit status (1 = running) | Read |
| AV 1 | Temperature_SUP | Supply air temperature | Read |
| AV 3 | Temperature_Room | Room temperature | Read |
| BV 1 | Alarm_General | Common fault | Read |
Enable & remote start
AV 1006 Operation_Mode selects 0 = manual operation, 1 = weekly program, 2 = BMS operation. In BMS operation the _BMS setpoint objects apply and AV 1014 Setpoint_Fan_Step_BMS switches the unit (1 = off, 2 = on); in manual or weekly-program mode the Offset_..._BMS objects shift the local setpoints. Values outside the allowed range are rejected and the old value is kept.
Sensors & values from the BMS
AV 37 Temperature_Outdoor_BMS and AV 71 Temperature_Room_BMS take outdoor and room temperature from the BMS once enabled in the service menu. Each value is plausibility-checked: outside -50 to 60 °C, or unchanged by at least 0.1 K for 24 hours, raises an alarm.
Network setup
- Factory device instance 77000; choose BACnet IP or BACnet Ethernet on the card's BACnet web page.
- Out of the box the card's web pages answer at 172.16.0.1 (factory login in the manual); IP settings are on Configuration > Network.
- An EDE file for the interface is offered on wolf.eu.
Watch out for
- AV 1055 Max_Power_Eheater is held in controller memory and saved to permanent memory only hourly, to spare the memory cells; after a power cut the last saved value applies until a new one is sent.
- With an active setpoint device on the unit, the temperature setpoint cannot be changed over the interface.
- In BMS operation a supply fan speed or pressure setpoint of 0 also sets the extract setpoint to 0.
- Remote alarm reset (BV 90) must be enabled by a service technician and is only offered on some series (CGL2 edu, CFL edu).

Integration notes
- Taken from section 7 (Interface description) of WOLF's Czech-language BACnet interface manual for the WRS-K (3065168, 2024-05); object types, instances, object names and units are printed in the tables, the descriptions there are Czech.
- Access follows the manual's sections: 7.1 read-only access, 7.2 write access. AV 1006 Operation_Mode is listed in both and is writable.
- The manual prints BV 90 twice: as Adiabatic_Cooling_Enable (air-heater thermostat) in the read table and as Alarm_Reset_BMS (WRS-K 5.7.000+) in the write section. Only the Alarm_Reset_BMS entry is kept; check on site.
- BV 87 and BV 90 both carry the name Adiabatic_Cooling_Enable in the read table; AV 1092 and AV 1093 are both printed as Pressure_Filter_SUP3. Names are kept as printed.
- Airflow objects marked in the manual (AV 1004/1005, 1010/1011, 1017/1018, 1022/1023) carry the real value divided by 10.
- Several objects need a minimum WRS-K software version (5.4.000 to 5.8.000), as footnoted in the manual.
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 WRS-K air handling unit controller - BACnet interface and exports what it actually has to Excel — free.

Questions about the WOLF WRS-K air handling unit controller - BACnet interface
How many BACnet points does the WOLF WRS-K air handling unit controller - BACnet interface have?
This list has 198 BACnet objects: 78 analog values, 120 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which WOLF WRS-K air handling unit controller - BACnet interface BACnet points are writable?
27 of the 198 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 WOLF WRS-K air handling unit controller - BACnet interface BACnet documentation?
The source is Rozhraní BACnet pro WRS-K - Návod k obsluze (BACnet interface for WRS-K, operating instructions, Czech) (3065168 | 202405), revision 2024-05, published free by WOLF at https://wolf.eu/download-asset/Ly95RHEwRzlhSGJQRUt0MlhvRnBKZz09.
What are the minimum BACnet points to integrate the WOLF WRS-K air handling unit controller - BACnet interface?
Start with AV 1006 Operation_Mode (Operating mode: 0 manual, 1 weekly program, 2 BMS); AV 1014 Setpoint_Fan_Step_BMS (Unit on/off in BMS mode: 1 = off, 2 = on); AV 15 Setpoint_Temperature_BMS (Temperature setpoint from the BMS, °C); AV 16 Setpoint_Speed_SUP_BMS (Supply fan speed setpoint from the BMS, %); AV 17 Setpoint_Speed_ETA_BMS (Extract fan speed setpoint from the BMS, %); BV 90 Alarm_Reset_BMS (Remote alarm reset (enable in service menu)); BV 5 Status_AHU (Unit status (1 = running)); AV 1 Temperature_SUP (Supply air temperature); AV 3 Temperature_Room (Room temperature); BV 1 Alarm_General (Common fault).
How do I enable BMS control of the WOLF WRS-K air handling unit controller - BACnet interface?
AV 1006 Operation_Mode selects 0 = manual operation, 1 = weekly program, 2 = BMS operation. In BMS operation the _BMS setpoint objects apply and AV 1014 Setpoint_Fan_Step_BMS switches the unit (1 = off, 2 = on); in manual or weekly-program mode the Offset_..._BMS objects shift the local setpoints. Values outside the allowed range are rejected and the old value is kept.
Can the BMS supply sensor values to the WOLF WRS-K air handling unit controller - BACnet interface?
AV 37 Temperature_Outdoor_BMS and AV 71 Temperature_Room_BMS take outdoor and room temperature from the BMS once enabled in the service menu. Each value is plausibility-checked: outside -50 to 60 °C, or unchanged by at least 0.1 K for 24 hours, raises an alarm.
How do I check these points on the real WRS-K air handling unit controller - BACnet interface?
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.
