WaterFurnace Dual Compressor Water-to-Air Heat Pump (FX10) BACnet points list
Updated 28 October 2026
These are the BACnet objects WaterFurnace publishes for its dual-compressor water-to-air heat pumps running the FX10 DDC controller. A BAS can read space, discharge and coil temperatures, occupancy and compressor/fan states, and can command occupancy, fan, compressor stages, the reversing valve and spare outputs directly. Setpoints and configuration live in flash-backed Analog/Multistate Values, so they should only be written occasionally.
This page lists 43 BACnet objects for the WaterFurnace Dual Compressor Water-to-Air Heat Pump (FX10) — 25 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from WaterFurnace’s own free documentation, linked below.

BMS integration notes: WaterFurnace Dual Compressor Water-to-Air Heat Pump (FX10)
The BAS can run this heat pump in two ways: command occupancy (MO1) and let the FX10 hold its occupied/unoccupied setpoints, or act as the thermostat and send fan, Y1, Y2 and O calls directly (MO2-MO5). Space temperature can be overridden from the network on AO2, and MO6 forces an emergency shutdown. Keep frequent writes on the volatile AO/MO points, not the flash-backed AV/MV setpoints.
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 |
|---|---|---|---|
| MO 1 | Occupancy Command | Occupied/unoccupied/bypass/standby command | Write |
| MO 6 | Emergency Override | Network emergency shutdown | Write |
| AV 1 | Occupied Cool | Occupied cooling setpoint (flash; write rarely) | Write |
| AV 2 | Occupied Heat | Occupied heating setpoint (flash; write rarely) | Write |
| MO 7 | Alarm Reset | Reset manual-reset alarms | Write |
| MI 2 | Mode | Auto or shutdown status | Read |
| MI 5 | Comp1 Cmd Status | Compressor 1 commanded on/off | Read |
| AI 1 | Space Temp | Space sensor temperature (terminals RS/AIC) | Read |
| AI 2 | Discharge Air | Discharge (supply) air temperature | Read |
| AI 8 | nvoAlarms | Active alarm code | Read |
Enable & remote start
The sheet has no separate BAS-enable point. MO6 Emergency Override puts the unit in shutdown (5) or back to auto (1). MO2-MO5 let the BAS send fan, compressor and reversing-valve calls directly.
Sensors & values from the BMS
AO2 Space Temp Ovrd overrides the space temperature reading from the network. It is a volatile output, so it reverts to uncommanded after a power cycle. The sheet does not mention a network outdoor-air input.
Watch out for
- AV/MV points are stored in flash (about 2,000,000 writes); write them only manually or by schedule, never from automatic reset logic.
- Output points (AO/MO) are volatile and go back to uncommanded after a power cycle, so rewrite them after power is restored.
- If the BAS shows 254 as uncommanded instead of 255, every multistate value is one lower (0=Off, 1=On).
- MO8 (BO5 electric heat) is interlocked with BI4. The sheet says it needs MV2 Electric Heat Mode set to EmgHeat, which seems to conflict with MV2's own description, so confirm on site.
- Alarm Reset needs a write of 2 followed by 1.

Integration notes
- Output-type points are volatile and fall back to uncommanded after a power cycle; unlimited writes.
- Value-type points (AV/MV) are stored in flash (about 2,000,000 write life); never write them from automatic reset logic.
- Multistate numbers assume the BAS shows 255 as uncommanded; if yours shows 254, every state number is one lower (0=Off, 1=On).
- No engineering units are printed in the source; temperatures are presumably degrees F.
- The sheet does not state the BACnet transport.
