Surface-mounted touch display for fan-coil climate control with up to 4 integrated sensors (Temperature, Humidity, CO₂ and VOC), Modbus RTU communication and BMS integration via e-Room Modular and LINX or LIOB automation servers.
In modern buildings, climate control is no longer limited to adjusting a temperature setpoint. Today, energy efficiency, indoor air quality and integration into BMS systems are key factors in any building automation project.
The e-Touch Display Mini by E-Controls is a compact surface-mounted touch display designed for advanced fan-coil control in hotel rooms, offices and tertiary spaces. Its main differentiator is the integration, within a single device, of up to four environmental sensors: temperature, relative humidity, CO₂ and volatile organic compounds (VOC). This allows not only precise thermal comfort control, but also indoor air quality monitoring and optimization of ventilation and energy-saving strategies.
Its philosophy is clear: maximum comfort, maximum environmental information and minimum installation complexity.
Fan-coil climate control with integrated environmental sensors
The e-Touch Display Mini connects to the e-Room Modular fan-coil controller, forming a complete zone-based climate control solution.
Depending on the model, the device can integrate:
• High-precision temperature sensor
• Relative humidity sensor
• CO₂ sensor
• Volatile Organic Compounds (VOC) sensor
This combination enables precise thermal control, indoor air quality monitoring to optimize room ventilation, advanced energy-saving strategies and improved comfort in offices and hotel rooms. The combined measurement of temperature, humidity, CO₂ and VOC makes it possible to act not only on the fan-coil, but also on air renewal systems when required by the project.
Surface mounting: ideal solution for new installations and retrofits
Unlike traditional flush-mounted thermostats, the e-Touch Display Mini is designed for 100% surface mounting, providing clear advantages, especially in office buildings:
• No flush-mount box required
• Reduced installation time
• Ideal for retrofit projects
• Minimizes on-site errors
• Simplifies maintenance and replacement
With compact dimensions (86 × 86 × 22 mm), its minimalist design perfectly fits hotel environments and high-end office interiors.
Integration with e-Room Modular: distributed control architecture
The e-Touch Display Mini communicates with the e-Room Modular controller via RS-485 bus.
The e-Room Modular manages:
• EC fan-coil 0-10V or 3-speed fan-coils
• On/off or modulating 0-10V valves
• Window contact
• Hotel keycard reader
• Universal inputs for additional sensors
• Outputs for lighting control
Communication is performed via Modbus RTU, enabling integration of each room or zone into a standard and open building automation network.
This modular approach allows scaling from single-room control to full-building management.
From room control to a complete BMS system
When global integration is required, the system can be expanded using LINX or LIOB automation servers, acting as communication gateways.
These platforms enable:
• Modbus RTU integration to BACnet/IP, Modbus TCP and other open protocols
• SCADA system supervision
• Centralized alarm management
• Historical data logging and trending
• Scheduling
• Global energy strategies
With this architecture, the e-Touch Display Mini evolves from a room display into part of a complete BMS system, based on open and interoperable protocols.
The result is a fully scalable building automation solution:
Display → e-Room Modular → LINX / LIOB → BMS / SCADA
Fast configuration via NFC
The device incorporates NFC technology, allowing wireless configuration via the E-Configurator APP. Configuration can be performed without powering the device, enabling cloning of settings across multiple units, reducing commissioning time and minimizing errors.
This system significantly lowers installation and maintenance costs in hotel and office projects with multiple units.
