Thermal Solutions Siemens RWF55 boiler controller (Universal Gateway ProtoAir) BACnet points list
Updated 7 November 2026
The ProtoAir Universal Gateway polls a Siemens RWF55 boiler controller over Modbus RTU and serves it on BACnet IP or BACnet MS/TP. Besides the inputs, setpoints, actuator position and burner alarm, this profile adds remote-operation objects: the BMS can switch the RWF55 to remote mode and then write its setpoint, switching thresholds, burner release, relays K2/K3/K6 and the actuator output.
This page lists 25 BACnet objects for the Thermal Solutions Siemens RWF55 boiler controller (Universal Gateway ProtoAir) — 17 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Thermal Solutions’s own free documentation, linked below.

BMS integration notes: Thermal Solutions Siemens RWF55 boiler controller (Universal Gateway ProtoAir)
Add the RWF55 as a profile in the ProtoAir Web Configurator with a unique Node-ID and discover it at 50000 + Node-ID. For monitoring read the analog inputs, actual setpoint, actuator position and burner alarm. For BMS control turn on remote operation (AV 10), then write the remote setpoint and burner release.
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 10 | Activation Remote Operation | Turns on remote (BMS) operation of the RWF55 | Write |
| AV 16 | Burner Release Remote Operation | Burner release while in remote operation | Write |
| AV 15 | Setpoint Remote | Setpoint used in remote operation | Write |
| AI 1 | Analog Input InP1 | Analog input 1 (process value) | Read |
| AI 4 | Actual Setpoint | Setpoint in use | Read |
| AI 8 | Actual Angular Positioning | Actuator position | Read |
| AI 9 | Burner Alarm | Burner alarm | Read |
| BI 1 | Com Status | Modbus link between ProtoAir and the RWF55 | Read |
Enable & remote start
Remote (BMS) operation is turned on with AV 10 Activation Remote Operation; the manual gives no values for it.
Network setup
- Device instance = Node_Offset (default 50,000) + the controller's Node-ID (1-255), so Node-ID 1 gives 50001.
- ProtoAir default IP address is 192.168.1.24, mask 255.255.255.0.
- Add each controller as a profile in the ProtoAir Web Configurator and give it a unique Node-ID.
- Set the RWF55 port to Modbus RTU, 38400 baud, no parity, 8 data bits, 1 stop bit, with a unique address.
Watch out for
- The manual gives no value ranges or state texts for the remote-operation objects; check the Siemens RWF55 documentation before writing them.
- Two sets of remote threshold objects carry identical names (AV 12-14 and AV 22-24).
Thermal Solutions Siemens RWF55 boiler controller (Universal Gateway ProtoAir) BACnet objects
Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.
Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes
- This ProtoAir profile has 25 objects; the older ProtoNode guide for EVA/EVO (listed separately) has only objects 1-9 of it.
- AV 12-14 and AV 22-24 carry the same names (switch-on and switch-off thresholds in remote mode); the manual does not say how the two sets differ.
- AI 3 and AI 7 are both named Analog Input InP3 in the manual.
- The table has no read/write column; AV objects (N2 analog outputs) are taken as writable.
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 Siemens RWF55 boiler controller (Universal Gateway ProtoAir) and exports what it actually has to Excel — free.
