BMS integration notes: WaterFurnace Aurora HydroLink2 for TruClimate 700 Single Screw Chiller
Integration in brief
Keep BV 37 Enabled and set BV 36 to Network while the BAS is in control. Pick the control method on MV 2 (setpoint, network, setpoint with enable) and the operating mode on MV 501, then write the cold and hot water setpoints AV 500/501. Watch MV 0 status, MV 1 mode and the evaporator leaving water temperature.
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 |
|---|---|---|---|
| BV 37 | SystemEnable_c | System enable; compressor stays off when Disabled | Command |
| BV 36 | NetworkControl_c | Set to Network while the BAS has control | Command |
| BV 2 | EmShutdown_c | Network emergency shutdown | Command |
| MV 501 | OperationMode_c | Operating mode: cooling, heating, free cooling, off... | Command |
| AV 500 | ColdWaterSP_c | Cold water setpoint | Command |
| AV 501 | HotWaterSP_c | Hot water setpoint | Command |
| BV 33 | AlarmReset_c | Alarm reset; return to Normal after the lockout clears | Command |
| MV 1 | UnitMode_st | Current operating mode | Read |
| AV 18 | EvapLvgWaterTemp_st | Evaporator leaving water temperature | Read |
| MV 0 | SystemStatus_st | Overall status: normal, alarm, shutdown, load shed... | Read |
Enable & remote start
BV 37 SystemEnable_c must be Enabled for the compressor to run, and the BAS sets BV 36 NetworkControl_c to Network when it takes control. MV 2 picks setpoint (AV 500/501), network or setpoint-with-enable control; MV 501 sets the operating mode. BV 2 EmShutdown_c forces an emergency shutdown.
Sensors & values from the BMS
AV 506/507 take BAS cold and hot water control temperatures when MV 502/503 are set to option 4 (Network). AV 508 and AV 510-515 take network loop temperatures; BV 503 switches the geothermal loop values between local and network.
Watch out for
- AV 307 NetVarSpdPct_c sets compressor capacity under network control; AV 327/328 hold the minimum and maximum capacity.
- BV 5 EnableManualOverride_c enables manual output overrides; normal logic keeps running underneath.
- Model and serial number registers (AV 210-227) are writable; don't write them from the BMS.
- Clear BV 33 AlarmReset_c back to Normal once the lockout condition is gone.

Integration notes
- Writable points are marked with the BACnet priorities they accept (in1, in4, in5, in8, in16) or 'Any Input'; they are shown here as commandable (C).
- Many object names carry over from the dual scroll HydroLink2 list, with 'Evap' and 'Cond' in place of 'Load' and 'Source'.
- AV 79 and BV 45 are printed with the name 'Do Not Map - FACTORY USE ONLY!!!'.
- MV 501 OperationMode_c is printed with default 8, which is not one of its listed states (1-7, 99).
- BV 310 NetIsoCtrl_c and BV 311 Net3wayCtrl_c carry descriptions copied from the delta-control rows; check their meaning on site.
- Valve position and capacity settings are printed as fractions (default 0.5 = 50 %) although the unit column says %. The sheet does not state the BACnet transport.
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 Aurora HydroLink2 for TruClimate 700 Single Screw Chiller 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 WaterFurnace Aurora HydroLink2 for TruClimate 700 Single Screw Chiller
How many BACnet points does the WaterFurnace Aurora HydroLink2 for TruClimate 700 Single Screw Chiller have?
This list has 202 BACnet objects: 154 analog values, 38 binary values, 10 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which WaterFurnace Aurora HydroLink2 for TruClimate 700 Single Screw Chiller BACnet points are writable?
134 of the 202 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 WaterFurnace Aurora HydroLink2 for TruClimate 700 Single Screw Chiller BACnet documentation?
The source is HydroLink2 Single Screw BACnet Objects, revision Version 1.00, published free by WaterFurnace at https://www.waterfurnace.com/literature/aurora/HydroLink2-BACnet-Objects-Single%20Screw-Version-1.00.xlsx.
What are the minimum BACnet points to integrate the WaterFurnace Aurora HydroLink2 for TruClimate 700 Single Screw Chiller?
Start with BV 37 SystemEnable_c (System enable; compressor stays off when Disabled); BV 36 NetworkControl_c (Set to Network while the BAS has control); BV 2 EmShutdown_c (Network emergency shutdown); MV 501 OperationMode_c (Operating mode: cooling, heating, free cooling, off); AV 500 ColdWaterSP_c (Cold water setpoint); AV 501 HotWaterSP_c (Hot water setpoint); BV 33 AlarmReset_c (Alarm reset; return to Normal after the lockout clears); MV 1 UnitMode_st (Current operating mode); AV 18 EvapLvgWaterTemp_st (Evaporator leaving water temperature); MV 0 SystemStatus_st (Overall status: normal, alarm, shutdown, load shed).
How do I enable BMS control of the WaterFurnace Aurora HydroLink2 for TruClimate 700 Single Screw Chiller?
BV 37 SystemEnable_c must be Enabled for the compressor to run, and the BAS sets BV 36 NetworkControl_c to Network when it takes control. MV 2 picks setpoint (AV 500/501), network or setpoint-with-enable control; MV 501 sets the operating mode. BV 2 EmShutdown_c forces an emergency shutdown.
Can the BMS supply sensor values to the WaterFurnace Aurora HydroLink2 for TruClimate 700 Single Screw Chiller?
AV 506/507 take BAS cold and hot water control temperatures when MV 502/503 are set to option 4 (Network). AV 508 and AV 510-515 take network loop temperatures; BV 503 switches the geothermal loop values between local and network.
How do I check these points on the real Aurora HydroLink2 for TruClimate 700 Single Screw Chiller?
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.
