The FT-06 Fan Coil Unit Thermostat is engineered to control fans, valves, and dampers in FCU and heating applications across industrial, commercial, and residential environments
The FT-06 Modbus & BACnet Thermostat is engineered to control fans, valves, and dampers in Fan Coil Unit (FCU) and heating applications. It features high-precision temperature sensing and supports reliable standalone operation or seamless BMS integration. Designed for versatility, the FT-06 ensures optimal comfort and energy efficiency in residential and commercial environments.
The system detects room temperature via an integrated sensor and compares it with your setpoint; in the event of a deviation, it automatically manages heating or cooling valves to maintain the perfect climate. Additionally, a connectable remote sensor can be utilized for external room temperature detection or as a changeover sensor in 2-pipe water systems.



Please Note: The FT-06 FCU thermostat utilizes a high-reliability relay module with a maximum of 9 terminals. Due to terminal capacity, specific terminal assignments depend on your selected configuration (e.g., Modbus vs. BACnet, or 3-speed vs. EC fan). Please choose the wiring scheme that aligns with your specific project requirements.

Our FT-06 controller is engineered to meet the highest international standards for safety, reliability, and environmental responsibility:
Safety & EMC: Fully compliant with CE (RED/LVD/EMC), UKCA, FCC, and ETL Listed standards.
Environmental: Certified by RoHS and REACH, ensuring lead-free and eco-friendly manufacturing.
Quality Management: Produced in an ISO 9001:2015 and ISO 14001:2015 certified facility.
The FT-06 is a scalable platform designed to adapt to diverse project needs. While it excels as a high-performance standalone controller, we also provide optional configurations for:
Smart Building Management: Optional Modbus RTU or BACnet MS/TP protocols for seamless BMS connectivity.
2-in-1 Control Logic: Optional integrated logic to manage both Fan Coil Units and Water Underfloor Heating in a single device.
Customized Hardware/Firmware: Tailored solutions including specialized PCB designs or user interface modifications.
Please specify these requirements when placing your order to ensure the optimal factory configuration.

A: Yes. The FT-06 is designed as a high-performance standalone fan coil thermostat. It features an intuitive digital interface for manual control of room temperature, fan speeds, and heating/cooling modes, making it ideal for standard residential and hotel applications.
A: Absolutely. The FT-06 supports both standard 3-speed fans and modern EC motors via its 0-10V modulating output. This allows for more precise airflow control and significant energy savings in modern HVAC installations.
A: The FT-06 is a versatile platform designed for various HVAC needs. While it excels as a dedicated FCU controller, the 2-in-1 linkage logic is a factory-optional configuration. If your project requires managing both a fan coil and water floor heating, please specify this requirement when placing your order. This specialized version will then be configured by our factory to prioritize floor heating comfort and system efficiency.
A: Yes, it is fully compatible with both 2-pipe and 4-pipe fan coil unit configurations. It also supports an optional external sensor for seasonal changeover detection in 2-pipe water systems.
A: For projects requiring centralized management, the FT-06 offers optional Modbus RTU or BACnet MS/TP communication protocols over an RS485 interface. This allows it to be easily integrated into building automation platforms like Siemens, Honeywell, or Schneider systems.
A: Yes, the FT-06 features Non-Volatile memory. All your program settings, setpoints, and engineering configurations are safely stored and will be automatically restored once power is back.
A: Our products are built to global standards. E-Top is an ISO 9001:2015 and ISO 14001:2015 certified factory. The FT06 series carries CE (RED/EMC/LVD), UKCA, and RoHS certifications.
