Produal TRC-P touchscreen room controller (BAC models) BACnet points list
Updated 12 November 2026
TRC-P is a wall-mounted touchscreen room controller with temperature, optional humidity and CO2, and analog, relay or triac outputs depending on the variant. BAC models talk BACnet MS/TP (B-ASC) on the RS-485 terminals. The user guide lists 43 standard objects: measurements and control demands, setpoints and dead zones, output limits and values, mode/status flags and fan speed.
This page lists 43 BACnet objects for the Produal TRC-P touchscreen room controller (BAC models) — 32 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-P touchscreen room controller (BAC models)
Set the BAC model to BACnet MS/TP with a unique MAC address and baud rate, then write the mode (MSV 0) and the nominal setpoint (AV 9). Read the room temperature, the active target and the control demands; outputs set to Network follow AV 27-29 and BV 7-8.
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 0 | Device Mode | Mode: 1 comfort, 2 eco, 3 off, 4 boost | Write |
| AV 9 | Nominal SP | Nominal temperature setpoint | Write |
| MV 2 | Fan | Fan speed: 1 = auto, 2-8 = speed 0-6 | Write |
| AV 0 | Built-In Sensor | Room temperature, °C | Read |
| AV 3 | Target | Target temperature in use | Read |
| AV 7 | Thermic 1 Demand | Heating/cooling demand, stage 1, % | Read |
| AV 6 | Fan Demand | Fan demand, % | Read |
| MV 1 | Alarm | Sensor/DI alarm word + 1 (1 = no alarm) | Read |
Enable & remote start
No separate enable point is listed; the comfort, eco, off and boost modes can be selected over the network (MSV 0) as well as from the display or a digital input.
Sensors & values from the BMS
AV 24 Network Temp. takes a temperature value from the network; inputs configured as Network are read from the bus instead of the terminals.
Network setup
- BACnet is only in the BAC models; device profile B-ASC.
- MS/TP baud 9600 (factory), 19200, 38400, 56000 or 76800 bit/s.
Watch out for
- BV 6 Update Nonvol stores settings to non-volatile memory; do not write it cyclically.
- Most configuration is in proprietary objects that many BACnet front ends cannot read; set it on the display or with the Produal tool.
Produal TRC-P touchscreen room controller (BAC models) BACnet objects
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, value ranges and units are from the user guide, chapter 5 (software 5.01 or newer); the guide has no read/write column, so access is inferred from what each object does.
- Configuration parameters sit in proprietary objects (Config1 etc., type proprietary-128) and are not listed here.
- The Alarm MSV carries a 5-bit alarm word plus 1 (internal sensor, RI1, RI2, humidity sensor, DI1).
- MS/TP 9600 (default), 19200, 38400, 56000 or 76800 bit/s, 1 stop bit, 1/2 unit load.
- Which inputs and outputs exist depends on the TRC-P variant; Y1-Y3 and DO1-DO2 follow the BMS only when the output is set to Network.
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-P touchscreen room controller (BAC models) and exports what it actually has to Excel — free.

Questions about the Produal TRC-P touchscreen room controller (BAC models)
How many BACnet points does the Produal TRC-P touchscreen room controller (BAC models) have?
This list has 43 BACnet objects: 31 analog values, 9 binary values, 3 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Produal TRC-P touchscreen room controller (BAC models) BACnet points are writable?
32 of the 43 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-P touchscreen room controller (BAC models) BACnet documentation?
The source is TRC-P - Touchscreen room controller, User Guide (chapter 5 BACnet) (EN - 6001NM2000ug), revision 16.05.2023, published free by Produal at https://produal-pim.rockon.io/rockon/api/v1/int/extmedia/openFile/01TGWJBKBRVW3XVAI6UBGLA4VEFWEAT22V.
What are the minimum BACnet points to integrate the Produal TRC-P touchscreen room controller (BAC models)?
Start with MV 0 Device Mode (Mode: 1 comfort, 2 eco, 3 off, 4 boost); AV 9 Nominal SP (Nominal temperature setpoint); MV 2 Fan (Fan speed: 1 = auto, 2-8 = speed 0-6); AV 0 Built-In Sensor (Room temperature, °C); AV 3 Target (Target temperature in use); AV 7 Thermic 1 Demand (Heating/cooling demand, stage 1, %); AV 6 Fan Demand (Fan demand, %); MV 1 Alarm (Sensor/DI alarm word + 1 (1 = no alarm)).
How do I enable BMS control of the Produal TRC-P touchscreen room controller (BAC models)?
No separate enable point is listed; the comfort, eco, off and boost modes can be selected over the network (MSV 0) as well as from the display or a digital input.
Can the BMS supply sensor values to the Produal TRC-P touchscreen room controller (BAC models)?
AV 24 Network Temp. takes a temperature value from the network; inputs configured as Network are read from the bus instead of the terminals.
How do I check these points on the real TRC-P touchscreen room controller (BAC models)?
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.
