Valent IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3) BACnet points list
Updated 7 November 2026
This is the full Appendix E points list of the IVE microprocessor controller (program IVE v1.3). It adds detailed alarm, status and configuration objects to the shorter BACnet integration guide subset. Objects marked as the BACnet short list are flagged in the descriptions; the controller talks BACnet MS/TP or BACnet IP once BACnet is licensed.
This page lists 152 BACnet objects for the Valent IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3) — 66 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Valent’s own free documentation, linked below.

BMS integration notes: Valent IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3)
Enable the unit with BV 2 and command occupancy with BV 3, and write the temperature setpoint AV 1 if needed. Watch BV 23 Global Alarm and IV 5 LatestAlm. If the BMS replaces hardwired sensors or drives fans, it must toggle BV 1 BMS Watchdog within the timeout delay.
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 3 | BMS_Occupancy_Command | Occupancy; Active = Unoccupied, Inactive = Occupied | Write |

Enable & remote start
BV 2 System_Enable enables or disables the unit from the BMS; BV 3 BMS_Occupancy_Command sets occupancy (Active = Unoccupied).
Heartbeat & communication loss
BV 1 BMS_Watchdog is required when the BMS takes the place of a hardwired sensor: the BMS toggles it between true and false within the timeout delay. If the timer expires the controller falls back to hardwired sensors and raises the BMS watchdog alarm (alarm 79). BV 24 shows the watchdog status.
Sensors & values from the BMS
Set the sensor source-select binary (BV 7-16, e.g. BV 8 Outside_Temp_Source_BMS) to BMS, then write the matching *_from_BMS analog value (e.g. AV 27 Outside_Temp_from_BMS). Fan speed, energy recovery and economizer control can be handed to the BMS with BV 17, BV 18, BV 35 and BV 36.
Network setup
- BACnet must be licensed on the controller; alarm 82 means the BACnet license is not installed.
- BACnet MS/TP or BACnet IP is selected and configured from the controller network settings screens.
Watch out for
- Status words are packed integers (IV objects); see the manual tables to decode them.

Integration notes
- Appendix E prints a Modbus register beside each BACnet object; only the BACnet side is listed here. Access is from the Read/Write column (RW shown as W).
- Objects marked * in the manual are the BACnet short list; they carry "[BACnet short list]" in the description.
- The shorter Greenheck IVE BACnet integration guide (487690, also in this library) has 95 objects; all 95 instances are here (84 with the same name), plus 57 more setpoints, BMS commands, dewpoint/enthalpy values and ramps.
- Binary states are the printed active/inactive texts (1 = active text).
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 IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3) 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 Valent IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3)
How many BACnet points does the Valent IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3) have?
This list has 152 BACnet objects: 26 analog inputs, 84 analog values, 2 binary inputs, 31 binary values, 9 integer values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Valent IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3) BACnet points are writable?
66 of the 152 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 Valent IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3) BACnet documentation?
The source is Microprocessor Controller for IVE - Reference Guide, Appendix E: Points List (487416 Rev. 2), revision 2026-05, published free by Valent at https://content.greenheck.com/public/DAMProd/Original/10025/487416-ive-microprocessor-controller-r2-may-2026_val.pdf.
What are the minimum BACnet points to integrate the Valent IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3)?
Start with BV 2 System_Enable (Enables or disables the unit); BV 3 BMS_Occupancy_Command (Occupancy; Active = Unoccupied, Inactive = Occupied); AV 1 Temperature_Setpoint (Occupied temperature setpoint); BV 1 BMS_Watchdog (Heartbeat when BMS controls fans or sensors); BV 4 Reset_All_Alarms (Remote alarm reset); AV 40 Unit_Status_Mode (Current operating mode code); AI 2 Supply_Temp_Analog_Input (Supply (discharge) air temperature); BV 23 Global_Alarm (Any active alarm); IV 5 LatestAlm (Most recent alarm code).
How do I enable BMS control of the Valent IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3)?
BV 2 System_Enable enables or disables the unit from the BMS; BV 3 BMS_Occupancy_Command sets occupancy (Active = Unoccupied).
Does the Valent IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3) need a BACnet heartbeat or have a communication timeout?
BV 1 BMS_Watchdog is required when the BMS takes the place of a hardwired sensor: the BMS toggles it between true and false within the timeout delay. If the timer expires the controller falls back to hardwired sensors and raises the BMS watchdog alarm (alarm 79). BV 24 shows the watchdog status.
Can the BMS supply sensor values to the Valent IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3)?
Set the sensor source-select binary (BV 7-16, e.g. BV 8 Outside_Temp_Source_BMS) to BMS, then write the matching *_from_BMS analog value (e.g. AV 27 Outside_Temp_from_BMS). Fan speed, energy recovery and economizer control can be handed to the BMS with BV 17, BV 18, BV 35 and BV 36.
How do I check these points on the real IVE Indoor Energy Recovery Ventilator Microprocessor Controller (IVE v1.3)?
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.
