FlowCon FIT / Energy FIT intelligent interface (ACC40023) BACnet points list
Updated 12 November 2026
The FIT interface sits between the BMS and a FlowCon PICV actuator and adds supply/return temperature (and optional pressure) sensors. It can run as a delta T energy valve, as a comfort (flow) PICV, or in a smart mode that balances room temperature against delta T, and it logs energy use. MV 6 sets which actuator and sensor set is fitted; many objects only work in some configurations.
This page lists 71 BACnet objects for the FlowCon FIT / Energy FIT intelligent interface (ACC40023) — 43 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from FlowCon’s own free documentation, linked below.

BMS integration notes: FlowCon FIT / Energy FIT intelligent interface (ACC40023)
Set MV 6 to the fitted actuator/sensor set and MV 5 to the control strategy, then write the delta T target (AV 4) or room values (AV 6/AV 7) or the control signal (AV 141). Read flow, delta T and energy; watch the alarm BVs.
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.

Enable & remote start
MV 5 picks how FIT controls the valve: 1/4 delta T target, 2 comfort (set flow), 3/5 smart (room temperature with delta T).
Heartbeat & communication loss
AV 143 sets the BACnet control fallback timeout (1-60 min, config 1); MV 43 shows the fallback action and BV 62 flags it.
Sensors & values from the BMS
Room temperature AV 6 and its target AV 7 are writable for the comfort and smart modes.
Network setup
- MS/TP MAC is MV 2 (0-127) and baud rate MV 1 (9600-115200).
- Choose units first: MV 3 temperature, MV 4 energy, MV 7 pressure, MV 39 flow.
Watch out for
- MV 6 Configuration is flagged in the PICS with "!!"; set it once to match the hardware.
- BV 4 resets the accumulated energy log.

Integration notes
- Several objects only work in certain configurations (MV 6); the PICS marks them "Works in config. ...".
- AV 138, AV 139, AV 164 and MV 41 are printed as no function.
- AV 165-168 are values FIT writes back to the actuator display; FIT overwrites them.
- TL 1 is a daily energy trend log with 1200 entries that rolls over.
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 FIT / Energy FIT intelligent interface (ACC40023) and exports what it actually has to Excel — free.

Questions about the FlowCon FIT / Energy FIT intelligent interface (ACC40023)
How many BACnet points does the FlowCon FIT / Energy FIT intelligent interface (ACC40023) have?
This list has 71 BACnet objects: 36 analog values, 17 binary values, 16 multi-state values, 1 trend log, 1 characterstring value. The exact set on a given unit depends on its firmware, installed options and configuration.
Which FlowCon FIT / Energy FIT intelligent interface (ACC40023) BACnet points are writable?
43 of the 71 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 FlowCon FIT / Energy FIT intelligent interface (ACC40023) BACnet documentation?
The source is Protocol Implementation Conformance Statement (PICS) for FlowCon FIT, revision 2026-06-26, published free by FlowCon at https://flowcon.com/fileadmin/user_upload/Pdf/Certificates/BACnet_PICS/FlowCon-BACnet-PICS-Statement-FlowCon-FIT.pdf.
What are the minimum BACnet points to integrate the FlowCon FIT / Energy FIT intelligent interface (ACC40023)?
Start with MV 5 Flow Control (Control strategy (delta T, comfort, smart)); AV 141 AnalogControlSignal (Control signal, %); AV 4 WaterTempDeltaTarget (Delta T target); AV 7 RoomTargetTemp (Room temperature target); AV 6 RoomTemperature (Room temperature from the BMS); AV 68 FlowRate (Current flow rate); AV 3 WaterTempDelta (Delta T); AV 10 EnergyConsumption (Current energy rate); BV 62 BACnetFallback-Alarm (BACnet fallback active); BV 59 PowerFailAlarm (Power failure alarm).
How do I enable BMS control of the FlowCon FIT / Energy FIT intelligent interface (ACC40023)?
MV 5 picks how FIT controls the valve: 1/4 delta T target, 2 comfort (set flow), 3/5 smart (room temperature with delta T).
Does the FlowCon FIT / Energy FIT intelligent interface (ACC40023) need a BACnet heartbeat or have a communication timeout?
AV 143 sets the BACnet control fallback timeout (1-60 min, config 1); MV 43 shows the fallback action and BV 62 flags it.
Can the BMS supply sensor values to the FlowCon FIT / Energy FIT intelligent interface (ACC40023)?
Room temperature AV 6 and its target AV 7 are writable for the comfort and smart modes.
How do I check these points on the real FIT / Energy FIT intelligent interface (ACC40023)?
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.
