Produal RTX-D Air Quality and Temperature Transmitter with Touchscreen
Produal's new RTX-D room transmitters represent a significant advancement in temperature and indoor air quality (IAQ) monitoring for smart buildings. Designed for integration into HVAC and BMS systems, they combine high accuracy, active control, and an advanced user interface in a single device.
Recognized at the 2026 MCE Excellence Awards, the RTX-D establishes itself as a benchmark solution for projects requiring a CO₂ sensor with a display, BACnet transmitter, and integrated environmental control, capable of meeting current demands for energy efficiency and comfort.
Accurate and reliable measurement in real-world environments
The RTX-D is built on the foundation of its patented Produal ProTemp™ technology, which guarantees temperature accuracy of up to ±0.3 °C, even in environments with drafts or pressure variations. This compensation capability ensures stable and reliable data, a key factor in any HVAC control system.
In addition to this accuracy, the IQS (Installation Quality Score) index evaluates the quality of the installation and provides a direct indication of measurement reliability. This allows for the detection of deviations and ensures optimal performance over time.
A complete IAQ sensor for environmental control
Beyond temperature, the RTX-D functions as a comprehensive indoor air quality sensor, capable of integrating various parameters into a single device. Depending on the configuration, it can measure relative humidity, CO₂, volatile organic compounds (VOCs), and even occupancy via a PIR sensor.
This combination allows ventilation systems to be adapted to actual conditions and occupancy levels, optimizing both comfort and energy consumption. In this respect, the RTX-D becomes a key tool for IAQ monitoring in offices, schools, or meeting rooms, where conditions are constantly changing.
Touchscreen and advanced user experience
One of the RTX-D's most distinctive features is its 2.8” colour touchscreen, which transforms how you interact with an environmental transmitter. The real-time display of temperature, CO₂, and air quality readings allows for immediate and intuitive understanding.
The interface is fully configurable, with up to six different screens and the ability to display multiple parameters simultaneously. This allows the device to be adapted to both technical requirements and end users, even incorporating visual indicators for air quality.
Furthermore, the device itself allows you to adjust set points or modify ventilation, making it an active component within the system.
Full integration with HVAC and BMS systems
The RTX-D is not just a transmitter, but also a control element. It incorporates an integrated P/PI controller that allows for the direct management of heating, cooling, ventilation, and air conditioning (HVAC) systems.
In terms of communications, it is ready to integrate into any modern architecture thanks to its compatibility with BACnet MS/TP (BTL certified), Modbus RTU, and 0–10 V analogue signals. This flexibility makes it a highly versatile HVAC transmitter, capable of adapting to a wide range of scenarios.
Furthermore, it features configurable inputs and outputs that allow for expanded functionality with external sensors or control of other system equipment. RTX transmitters can function as I/O modules: they can input values from third-party devices without Modbus or BACnet communication via Modbus, and they can also output a 0–10 V or digital signal via a register from the Building Management System (BMS).
Efficient configuration and simplified commissioning
The RTX-D's installation and setup have been optimized to reduce time and errors. Using the MyProdual mobile app, you can configure the device, view real-time data, and adjust the interface intuitively.
The MyTool Connect Bluetooth dongle allows you to access the device without physical connections, greatly simplifying setup and maintenance.
A key solution for efficient and healthy buildings
In short, the Produal RTX-D goes beyond a conventional sensor. It's a comprehensive solution for temperature measurement, CO₂ control, and indoor air quality monitoring, with integration and control capabilities.
When measurements are reliable, the system performs better. And when the system performs better, energy consumption is reduced, comfort is improved, and regulatory compliance is ensured.
The RTX-D is thus positioned as a safe bet for projects seeking to combine technology, efficiency, and well-being.
