Thermal Solutions EVA / EVO boiler - RM7800 flame safeguard (ProtoNode) BACnet points list
Updated 28 October 2026
The RM7800 burner control on Thermal Solutions EVA/EVAW/EVO/EVOW boilers is read through a ProtoNode FPC-N34 gateway that polls it over Modbus RTU and serves it on BACnet IP or BACnet MS/TP. All 37 objects are read-only: flame signal, cycle and hour counters, fault and first-out codes, one flag per burner sequence state, and the limit and interlock inputs.
This page lists 37 BACnet objects for the Thermal Solutions EVA / EVO boiler - RM7800 flame safeguard (ProtoNode) — 0 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 EVA / EVO boiler - RM7800 flame safeguard (ProtoNode)
Wire the RM7800 display module Modbus terminals to the ProtoNode, set it to 19200 8N1 with a unique Node-ID, add the RM7800 profile in the Web Configurator, and discover it at 50000 + Node-ID. It is a monitoring profile: read the run, alarm and lockout flags, the fault and first-out codes and the flame signal.
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 |
|---|---|---|---|
| AI 58 | Run | Burner in run (1 = on) | Read |
| AI 1 | Flame Signal | Flame signal strength | Read |
| AI 4 | Burner Fault Code | Current burner fault code | Read |
| AI 62 | Alarm | Flame safeguard alarm (1 = on) | Read |
| AI 64 | Lockout | Burner locked out (1 = on) | Read |
| BI 1 | Com Status | Modbus link between ProtoNode and the RM7800 | Read |
Enable & remote start
None: the RM7800 profile is read-only, so start/stop is not available over BACnet.
Network setup
- Device instance = Node_Offset (default 50,000) + the controller's Modbus Node-ID, so Node-ID 1 gives 50001.
- ProtoNode default IP is 192.168.1.24 (255.255.255.0); change it in the FS-GUI under Setup > Network Settings.
- FPC-N34 S-bank DIP switches pick the protocol: all Off = BACnet IP, S0 On = BACnet MS/TP, S2 On = BACnet MS/TP single node.
- BACnet MS/TP: one MAC address (1-127) for the whole ProtoNode on A-bank DIP switches; baud on B-bank switches, factory default 38400.
- Modbus side: every RWF40, RWF55 and RM7800 must run Modbus RTU at 19200, 8N1 with a unique Node-ID (1-255); add each one as a profile in the Web Configurator.
- With more than one controller on a ProtoNode set BACnet Virtual Server Nodes to Yes; give each ProtoNode on a subnet its own BACnet Network Number (default 50).
Watch out for
- Sequence states are AI objects holding 0/1, not binary objects.
- RM7800 wiring: A to ProtoNode Tx+, B to Rx-, C to GND; a factory terminal strip (AO/BO/SO) may already combine it with the RWF controller.

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
- Each connected controller shows up as its own BACnet device on the ProtoNode FPC-N34 gateway.
- Monitoring only: the RM7800 profile has no writable objects.
- The sequence-state points (Initiate to Lockout) are analog inputs that carry a 0/1 on/off value.
- The guide gives no fault-code or first-out-code tables; see the RM7800 documentation.
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. Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the EVA / EVO boiler - RM7800 flame safeguard (ProtoNode) and exports what it actually has to Excel — free.
