WaterFurnace Single Compressor Water-to-Air Console Unit (FX10) BACnet points list
Updated 4 November 2026
BACnet objects for WaterFurnace's single-compressor console heat pump on the FX10 controller. It is a short list: space and discharge air temperatures, effective setpoints, an alarm code, flash-stored setpoints and limits, and read-only status of the fan, compressor, reversing valve and two digital inputs. The BAS can shift both setpoints with Space Setpoint (AO1) and override the space temperature (AO2).
This page lists 24 BACnet objects for the WaterFurnace Single Compressor Water-to-Air Console Unit (FX10) — 12 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 Single Compressor Water-to-Air Console Unit (FX10)
The console unit runs on its own setpoints; the BAS mainly adjusts them and monitors. Use Space Setpoint (AO1) to move both setpoints from one command, or AO2 to feed a network space temperature. Keep frequent writes on the volatile AO points, not the flash-backed AV 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 |
|---|---|---|---|
| AO 1 | Space Setpoint | Midpoint setpoint; shifts heat and cool together | Write |
| AV 1 | Occupied Cool | Occupied cooling setpoint (flash; write rarely) | Write |
| AV 3 | Occupied Heat | Occupied heating setpoint (flash; write rarely) | Write |
| MI 1 | Mode Status | Unit mode: auto or shutdown | Read |
| MI 6 | Compr Cmd Status | Compressor commanded on/off | Read |
| AI 1 | Space Temperature | Space sensor temperature (terminals RS/AIC) | Read |
| AI 2 | Discharge Air | Discharge (supply) air temperature | Read |
| AI 5 | Alarms | Active alarm code | Read |
Enable & remote start
The sheet has no enable, occupancy or shutdown command; the unit runs on its local control and the BAS adjusts setpoints.
Sensors & values from the BMS
AO2 Space Temp Override replaces the space sensor reading from the network. It is a volatile output, so it reverts to uncommanded after a power cycle.
Watch out for
- AV 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) are volatile and go back to uncommanded after a power cycle, so rewrite them after power returns.
- If the BAS shows 254 as uncommanded instead of 255, every multistate value is one lower.

Integration notes
- Output-type points (AO/MO) 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).
- Units are not printed on the sheet. The sheet does not state the BACnet transport.
- This sheet has no occupancy command, fan/compressor command or alarm reset point.
- Alarm codes 5-7 are not listed in the alarm table.
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 Single Compressor Water-to-Air Console Unit (FX10) and exports what it actually has to Excel — free.

Where is the official WaterFurnace Single Compressor Water-to-Air Console Unit (FX10) BACnet documentation?
The source is BACnet Points for Single Compressor Water-to-Air Console Units Utilizing the FX10 Controller (PROSSWAC-02), revision 2013-02, published free by WaterFurnace at https://www.waterfurnace.com/downloads/ddc/BACnet-Resources/BACnet-points-pdfs/PROSSWAC-02.pdf.
What are the minimum BACnet points to integrate the WaterFurnace Single Compressor Water-to-Air Console Unit (FX10)?
Start with AO 1 Space Setpoint (Midpoint setpoint; shifts heat and cool together); AV 1 Occupied Cool (Occupied cooling setpoint (flash; write rarely)); AV 3 Occupied Heat (Occupied heating setpoint (flash; write rarely)); MI 1 Mode Status (Unit mode: auto or shutdown); MI 6 Compr Cmd Status (Compressor commanded on/off); AI 1 Space Temperature (Space sensor temperature (terminals RS/AIC)); AI 2 Discharge Air (Discharge (supply) air temperature); AI 5 Alarms (Active alarm code).
How do I enable BMS control of the WaterFurnace Single Compressor Water-to-Air Console Unit (FX10)?
The sheet has no enable, occupancy or shutdown command; the unit runs on its local control and the BAS adjusts setpoints.
Can the BMS supply sensor values to the WaterFurnace Single Compressor Water-to-Air Console Unit (FX10)?
AO2 Space Temp Override replaces the space sensor reading from the network. It is a volatile output, so it reverts to uncommanded after a power cycle.
How do I check these points on the real Single Compressor Water-to-Air Console Unit (FX10)?
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.
