Wilo IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP) BACnet points list
Updated 7 November 2026
The IF-Module BACnet plugs into older Wilo electronic pumps and makes the pump a BACnet MS/TP device (master from module software 2.00, slave if the MAC address is 128 or higher). Wilo's functional description gives one fixed object list of 57 objects: pump measurements, the bus setpoint and control-mode command, on/off and override commands, status bits, and the error and bus-command-timer objects. Each object is marked with the pump families that support it.
This page lists 57 BACnet objects for the Wilo IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP) — 21 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Wilo’s own free documentation, linked below.

BMS integration notes: Wilo IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP)
Write BO 0 Bus Command Pump on and AO 0 Bus Setpoint, choose the control mode with MO 0, and keep the Bus Command Timer (MO 1) active so the pump stays under bus control. Read BI 10 Pump is operating, speed, power and the warning/error status bits, with MI 1 for the current error code.
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 |
|---|---|---|---|
| BO 0 | Bus Command Pump on | Pump on/off command | Command |
| MO 0 | Bus Control Mode | Control mode command | Command |
| AO 0 | Bus Setpoint | Setpoint / duty point, % | Command |
| MO 1 | Bus Command Timer | Write SET (2) before each timeout to keep bus control | Command |
| BI 10 | Status Pump is operating | Pump running | Read |
| AI 1 | Speed | Pump speed, 1/min | Read |
| AI 4 | Power Rating | Power, W | Read |
| BI 12 | Status Warning Present | Warning present | Read |
| BI 13 | Status Error Present | Error present | Read |
| MI 1 | Current Warning/Error Message | Current warning/error code | Read |
Enable & remote start
MO 1 Bus Command Timer decides who controls the pump: MANUAL (the relinquish default) lets the pump menu and the bus both write, last write wins; SET locks the local menu for the timeout; OFF blocks local operation permanently. Commands then follow a fixed priority: Ext. off input at the pump, Override off, Override max, Override min, Override on.
Heartbeat & communication loss
With MO 1 = SET the BMS must write SET again before the Bus Command Timer timeout (AO 8, default 300 s, module SW 2.00+). When it lapses the state goes to RESET: local operation is possible again and bus writes are blocked. Use SET_PRESET instead to load the preset values (AO 100, BO 100, MO 100, MO 101) on bus failure. MI 2 shows the timer state.
Network setup
- The module is MS/TP master from module software 2.00; a MAC address of 128 or higher makes it an MS/TP slave. Baud rates 9600-115200.
- The device instance is set with the pump menu parameters C, E and F (instance split as hex digits, per the IF-Module manual).
Watch out for
- Some commandable outputs use a floating default: the module writes it virtually at priority 16, so relinquishing all priorities does not always return the static relinquish default.
- At double pumps fit the IF-Module in the master pump and use the integrated double-pump management.

Integration notes
- Taken from the BACnet object descriptions (section 6.2) in Wilo's IF-Module functional description; object type comes from the section heading (Analog Inputs, Analog Outputs, Binary Inputs, Binary Outputs, Multistate Inputs, Multistate Outputs).
- Wilo marks each object with the pump families that support it (Stratos, IL-E family, MVIE family). Where an object is not supported by all three, the description names the families; 'Provided by the module' means the IF-Module itself supplies it.
- Access: inputs (AI, BI, MI) are read-only; outputs (AO, BO, MO) are commandable, each printed with a relinquish default.
- Multistate state texts list only the first word of each state; several states are marked reserved or valid only for some pump families.
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 IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP) 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 Wilo IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP)
How many BACnet points does the Wilo IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP) have?
This list has 57 BACnet objects: 16 analog inputs, 10 analog outputs, 17 binary inputs, 5 binary outputs, 3 multi-state inputs, 6 multi-state outputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Wilo IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP) BACnet points are writable?
21 of the 57 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 Wilo IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP) BACnet documentation?
The source is WILO BACnet - IF-Module functional description (BACnet objects, section 6.2) (wilo173472), published free by Wilo at https://cms.media.wilo.com/cdndoc/wilo173472/3657298/wilo173472.html.
What are the minimum BACnet points to integrate the Wilo IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP)?
Start with BO 0 Bus Command Pump on (Pump on/off command); MO 0 Bus Control Mode (Control mode command); AO 0 Bus Setpoint (Setpoint / duty point, %); MO 1 Bus Command Timer (Write SET (2) before each timeout to keep bus control); BI 10 Status Pump is operating (Pump running); AI 1 Speed (Pump speed, 1/min); AI 4 Power Rating (Power, W); BI 12 Status Warning Present (Warning present); BI 13 Status Error Present (Error present); MI 1 Current Warning/Error Message (Current warning/error code).
How do I enable BMS control of the Wilo IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP)?
MO 1 Bus Command Timer decides who controls the pump: MANUAL (the relinquish default) lets the pump menu and the bus both write, last write wins; SET locks the local menu for the timeout; OFF blocks local operation permanently. Commands then follow a fixed priority: Ext. off input at the pump, Override off, Override max, Override min, Override on.
Does the Wilo IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP) need a BACnet heartbeat or have a communication timeout?
With MO 1 = SET the BMS must write SET again before the Bus Command Timer timeout (AO 8, default 300 s, module SW 2.00+). When it lapses the state goes to RESET: local operation is possible again and bus writes are blocked. Use SET_PRESET instead to load the preset values (AO 100, BO 100, MO 100, MO 101) on bus failure. MI 2 shows the timer state.
How do I check these points on the real IF-Module BACnet / IF-Module BACnet Stratos (BACnet MS/TP)?
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.
