IMI Hydronic TA-Smart smart control valve (BACnet MS/TP and BACnet IP) BACnet points list

Updated 12 November 2026

Short answer

TA-Smart is a 2-way control valve with an integrated ultrasonic flow meter and supply/return temperature sensors, so it can control flow, power, differential pressure (Dp version) or position and meter energy. The MS/TP and IP versions publish the same 140 objects: valve data, setpoints and measurements in two selectable unit sets, regime limits, temperature limitation, overrides, status words, error/event logs and integer energy counters.

This page lists 140 BACnet objects for the IMI Hydronic TA-Smart smart control valve (BACnet MS/TP and BACnet IP) — 69 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from IMI Hydronic’s own free documentation, linked below.

BMS integration notes: IMI Hydronic TA-Smart smart control valve (BACnet MS/TP and BACnet IP)

Integration in brief

Set ControlSource (MSV 4) to Bus and choose the ControlMode (MSV 2), then write RelativeSetpoint AV 23 as a percentage of the regime maximum. Read measured flow, temperatures, power and energy, and watch StatusSummary MSI 10. Enable the cyclic timeout if the valve should fall back when the BMS goes quiet.

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
MV 4	ControlSource	Must be 2 = Bus for BMS control	Write
MV 2	ControlMode	1 flow, 2 power, 3 Dp, 4 position	Write
AV 23	RelativeSetpoint	Setpoint, % of max for the regime	Write
MV 17	CyclicControlTimeoutEnabled	Fallback timeout: 2 = active	Write
AV 43	CyclicControlTimeout	Fallback delay, minutes	Write
AI 20	MeasuredFlow_unit1	Measured flow (FlowUnit1)	Read
AI 22	MeasuredSupplyTemp_degC	Supply temperature, °C	Read
AI 24	MeasuredReturnTemp_degC	Return temperature, °C	Read
AI 29	MeasuredPower_unit1	Measured power (PowerUnit1)	Read
MI 10	StatusSummary	1 ok, 2 error, 3 warning	Read

Enable & remote start

The valve takes AV 23 only when ControlSource (MSV 4) is Bus; with Analog the bus is monitoring only.

Heartbeat & communication loss

With CyclicControlTimeoutEnabled (MSV 17) active, the valve starts its fallback (moves to a user-set position) when no bus or analog control signal arrives within CyclicControlTimeout (AV 43, 1-1440 min, default 20).

Network setup

MS/TP baud Auto, 9600 (default), 19200-115200.
Device instance defaults to a value computed from the serial number; Object_Name, Location and Max_Master are writable.
The IP version supports BACnet/IP and foreign-device registration.

Watch out for

A bus override (MSV 13 OverrideType) returns to normal after 3 hours by default.
CurrentRegime (MSV 12) can only be written when RegimeSwitching is Bus.
Check the unit objects (MSV 5-10) before scaling _unit1/_unit2 values.

Integration notes

Taken from the TA-Smart BACnet MS/TP PICS (07.2026); the TA-Smart BACnet IP PICS (https://cdn.tessa.imihy.eimed-project.de/673551/TA-Smart_BACnet_IP_Protocol_Implementation.pdf) prints the identical object table.
Most values come in two unit sets: _unit1/_unit2 objects use the units chosen in MSV 5-10, 15-16 and 18-19 (for example FlowUnit1 = m3/h by default, FlowUnit2 = GPM).
The error and event logs are printed as ranges: AV 50 LastErrors[1] ... AV 59 LastErrors[10] and AV 60 LastEvents[1] ... AV 69 LastEvents[10]; only the first and last of each are listed here.
Footnotes: Dp objects only on TA-Smart-Dp; temperature limitation objects not on the Dp; others need firmware 8.0.0 to 13.0.0 (markers removed from names).
MSI 6-9 are not printed in the 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 TA-Smart smart control valve (BACnet MS/TP and BACnet IP) 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 IMI Hydronic TA-Smart smart control valve (BACnet MS/TP and BACnet IP)

How many BACnet points does the IMI Hydronic TA-Smart smart control valve (BACnet MS/TP and BACnet IP) have?

This list has 140 BACnet objects: 48 analog inputs, 51 analog values, 14 multi-state inputs, 23 multi-state values, 4 positive integer values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which IMI Hydronic TA-Smart smart control valve (BACnet MS/TP and BACnet IP) BACnet points are writable?

69 of the 140 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 IMI Hydronic TA-Smart smart control valve (BACnet MS/TP and BACnet IP) BACnet documentation?

The source is TA-Smart BACnet MS/TP Protocol Implementation Conformance Statement - PICS, revision 07.2026, published free by IMI Hydronic at https://cdn.tessa.imihy.eimed-project.de/673548/TA-Smart_BACnet_MS_TP_Protocol_Implementation.pdf.

What are the minimum BACnet points to integrate the IMI Hydronic TA-Smart smart control valve (BACnet MS/TP and BACnet IP)?

Start with MV 4 ControlSource (Must be 2 = Bus for BMS control); MV 2 ControlMode (1 flow, 2 power, 3 Dp, 4 position); AV 23 RelativeSetpoint (Setpoint, % of max for the regime); MV 17 CyclicControlTimeoutEnabled (Fallback timeout: 2 = active); AV 43 CyclicControlTimeout (Fallback delay, minutes); AI 20 MeasuredFlow_unit1 (Measured flow (FlowUnit1)); AI 22 MeasuredSupplyTemp_degC (Supply temperature, °C); AI 24 MeasuredReturnTemp_degC (Return temperature, °C); AI 29 MeasuredPower_unit1 (Measured power (PowerUnit1)); MI 10 StatusSummary (1 ok, 2 error, 3 warning).

How do I enable BMS control of the IMI Hydronic TA-Smart smart control valve (BACnet MS/TP and BACnet IP)?

The valve takes AV 23 only when ControlSource (MSV 4) is Bus; with Analog the bus is monitoring only.

Does the IMI Hydronic TA-Smart smart control valve (BACnet MS/TP and BACnet IP) need a BACnet heartbeat or have a communication timeout?

How do I check these points on the real TA-Smart smart control valve (BACnet MS/TP and BACnet IP)?

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.
