Produal TRC-A-3A touchscreen apartment controller (BAC model) BACnet points list
Updated 12 November 2026
TRC-A-3A is a touchscreen apartment controller for ventilation and room temperature, with home/away/boost modes, three analog outputs and digital inputs. The BAC model speaks BACnet MS/TP (B-ASC). Its object map differs from the TRC-P: measurements are AIs, settings AVs, digital inputs BIs and mode flags BOs (40 objects).
This page lists 40 BACnet objects for the Produal TRC-A-3A touchscreen apartment controller (BAC model) — 27 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Produal’s own free documentation, linked below.

BMS integration notes: Produal TRC-A-3A touchscreen apartment controller (BAC model)
Give the BAC model a unique MS/TP MAC address and baud rate, then write the home/away/boost mode (MSV 0) and the nominal setpoint (AV 0), and read temperature, humidity, CO2 and the fan demand.
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.

|---|---|---|---|
| MV 0 | Device Mode | Mode: 1 home, 2 away, 3 boost | Write |
| AV 0 | Nominal SP | Nominal temperature setpoint | Write |
| AV 15 | CO2 SP | CO2 setpoint, ppm | Write |
| AI 0 | Built-In Sensor | Room temperature, °C | Read |

| AI 5 | CO2 | Room CO2, ppm | Read |
| AI 6 | Fan Demand | Ventilation demand, % | Read |
| MV 1 | Alarm | Alarm word + 1 (1 = no alarm) | Read |
Enable & remote start
No separate enable point is listed; home, away and boost can be selected over the network (MSV 0), from the display or by a digital input.
Sensors & values from the BMS
AV 14 Network Temp. takes a temperature value from the network.
Network setup
- BACnet is only in the BAC model; device profile B-ASC.
- MS/TP baud 9600 (factory), 19200, 38400, 56000 or 76800 bit/s.
Watch out for
- BO 3 Update Nonvol stores settings to non-volatile memory; do not write it cyclically.

Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.
Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes
- Object names, ranges and units are from the user guide, chapter 5 (software 5.02 or newer); the guide has no read/write column, so access is inferred from what each object does.
- Configuration parameters sit in proprietary objects (type proprietary-128) and are not listed.
- The Alarm MSV carries a 7-bit alarm word plus 1 (sensors, DI1, supply and extract air flow).
- MS/TP 9600 (default), 19200, 38400, 56000 or 76800 bit/s.
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 TRC-A-3A touchscreen apartment controller (BAC model) and exports what it actually has to Excel — free.

Questions about the Produal TRC-A-3A touchscreen apartment controller (BAC model)
How many BACnet points does the Produal TRC-A-3A touchscreen apartment controller (BAC model) have?
This list has 40 BACnet objects: 8 analog inputs, 20 analog values, 4 binary inputs, 5 binary outputs, 3 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Produal TRC-A-3A touchscreen apartment controller (BAC model) BACnet points are writable?
27 of the 40 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. The source has no read/write column, so this is inferred from object type.
Where is the official Produal TRC-A-3A touchscreen apartment controller (BAC model) BACnet documentation?
The source is TRC-A-3A - Touchscreen apartment controller, User Guide (chapter 5 BACnet) (EN - 6001CBM2000ug), revision 14.09.2023, published free by Produal at https://produal-pim.rockon.io/rockon/api/v1/int/extmedia/openFile/01TGWJBKCSDMEWJVUDQNGKE26DEI5JQNNU.
What are the minimum BACnet points to integrate the Produal TRC-A-3A touchscreen apartment controller (BAC model)?
Start with MV 0 Device Mode (Mode: 1 home, 2 away, 3 boost); AV 0 Nominal SP (Nominal temperature setpoint); AV 15 CO2 SP (CO2 setpoint, ppm); AI 0 Built-In Sensor (Room temperature, °C); AI 4 Humidity (Room relative humidity); AI 5 CO2 (Room CO2, ppm); AI 6 Fan Demand (Ventilation demand, %); MV 1 Alarm (Alarm word + 1 (1 = no alarm)).
How do I enable BMS control of the Produal TRC-A-3A touchscreen apartment controller (BAC model)?
No separate enable point is listed; home, away and boost can be selected over the network (MSV 0), from the display or by a digital input.
Can the BMS supply sensor values to the Produal TRC-A-3A touchscreen apartment controller (BAC model)?
AV 14 Network Temp. takes a temperature value from the network.
How do I check these points on the real TRC-A-3A touchscreen apartment controller (BAC model)?
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.
